Fish that communicate by getting red
Wed, Sep 24, 2008

Most fish can’t even recognize the color red, the exception of them being some deep sea fish, yet Enneapterygius pusillus found a really interesting way of communicating. It literally glows in a deep red color, signaling different forms of intent.
According to a study conducted in 2008 in September, at least 32 species of reef fish that lower than 10 meters below sea level can use this method of communicating. This baffled scientists, as they believed red had no real importance for fish, as it has a longer wavelength, and fish are generally better at detecting colors with a shorter wavelength, such as blue or green.
“Marine fish are generally assumed not to see or use red light, with the exception of some deep-sea fish,” lead researcher Nico Michiels of the University of Tuebingen in Germany said in an email. “Our discovery shows that there is a lot of red fluorescence that is very indicative of an active role of red in fish communication.”
The reason why they do this is still not clear, but it could have something to do with the fact that glowing red requires less energy than glowing blue or green, because red is much more power efficient than blue. Fluorescence appears when light is absorbed at a certain wavelength, and then sent back at a different one almost instantly.

this is just of the mainy miricals of God.
——————————————————————————–
ANIMALS MENTIONED IN THE QUR’AN
For you and for your livestock to enjoy. (Surat an-Na’ziat, 33)
And also animals for riding and for haulage and animals for slaughtering and for wool. Eat what Allah has provided for you and do not follow in the footsteps of Satan. He is an outright enemy to you. (Surat al-An’am, 142)
And He created livestock. There is warmth for you in them, and various uses and some you eat. (Surat an-Nahl, 5)
There is instruction for you in cattle. From the contents of their bellies, from between the dung and blood, We give you pure milk to drink, easy for drinkers to swallow. (Surat an-Nahl, 66)
WILD ANIMALS
When the wild beasts are all herded together, (Surat at-Takwir, 5)
CALF
And when We allotted to Musa forty nights. Then you adopted the Calf when he had gone and you were wrongdoers. (Surat al-Baqara, 51)
And when Musa said to his people, ‘My people, You wronged yourselves by adopting the Calf so turn towards your Maker and kill yourselves. That is the best thing for you in your Maker’s sight.’ And He turned towards you. He is the Ever-Returning, the Most Merciful. (Surat al-Baqara, 54)
Then he produced a calf for them, a physical form which made a lowing sound. So they said, ‘This is your god - and Musa’s God as well, but he forgot.’ (Surah Ta Ha, 88)
So he (Ibrahim) slipped off to his household and brought a fattened calf. (Surat adh-Dhariyat, 26)
Musa brought you the Clear Signs; then, after he left, you adopted the Calf and were wrongdoers. Remember when We made a covenant with you and lifted up the Mount above your heads: ‘Take hold vigorously of what We have given you and listen.’ They said, ‘We hear and disobey.’ They were made to drink the Calf into their hearts because of their disbelief. Say, ‘If you are believers, what an evil thing your faith has made you do.’ (Surat al-Baqara, 92-93)
LIVESTOCK
And mankind and beasts and livestock are likewise of varying colours. Only those of His servants with knowledge have fear of Allah. Allah is Almighty, Ever-Forgiving. (Surah Fatir, 28)
He created you from a single self, then produced its mate from it, and sent down livestock to you - eight kinds in pairs. He creates you stage by stage in your mothers’ wombs in a threefold darkness. That is Allah, your Lord. Sovereignty is His. There is no god but Him. So what has made you deviate? (Surat az-Zumar, 6)
The Bringer into Being of the heavens and the earth: He has given you mates from among yourselves, and given mates to the livestock, in that way multiplying you. Nothing is like Him. He is the All-Hearing, the All-Seeing. (Surat ash-Shura, 11)
COW
He said, ‘He says it should be a cow not trained to plough or irrigate the fields - completely sound, without a blemish on it.’ They said, ‘Now you have brought the truth.’ So they sacrificed it - but they almost did not do it. (Surat al-Baqara, 71)
The King declared, ‘I dreamt of seven fat cows which seven thin ones ate and seven green ears of wheat and seven others which were dry. O counsellors! Explain my dream to me if you are those who can interpret visions!’ (Surah Yusuf, 43)
And when Musa said to his people, ‘Allah commands you to sacrifice a cow,’ they said, ‘What! Are you making a mockery of us?’ He said, ‘I seek refuge with Allah from being one of the ignorant!’ (Surat al-Baqara, 67)
EWE
This brother of mine has ninety-nine ewes and I have only one. He said, “Let me have charge of it,” and got the better of me with his words.’ He said, ‘He has wronged you by asking for your ewe to add to his ewes. Truly many partners are unjust to one another -except those who believe and do right actions, and how few they are!’ Dawud realised that We had put him to the test. He begged forgiveness from his Lord and fell down prone, prostrating, and repented. (Surah Sâd, 23-24)
PORK
He has only forbidden you carrion, blood and pork and what has been consecrated to other than Allah. But anyone who is forced to eat it - without desiring it or going to excess in it - commits no crime. Allah is Ever-Forgiving, Most Merciful. (Surat al-Baqara, 173)
Forbidden for you are carrion, blood and pork, and what has been consecrated to other than Allah, and animals which have been strangled, and animals which have been killed by a blow, and animals which have fallen to their death, and animals which have been gored, and animals which wild beasts have eaten - except those you are able to slaughter properly - and animals which have been sacrificed on altars, and deciding things by means of divining arrows - that is deviance. Today the disbelievers have despaired of overcoming your religion. So do not be afraid of them but be afraid of Me. Today I have perfected your religion for you and completed My blessing upon you and I am pleased with Islam as a religion for you. But if anyone is forced by hunger, not intending any wrongdoing, Allah is Ever-Forgiving, Most Merciful. (Surat al-Ma’ida, 3)
DONKEY
Be moderate in your tread and lower your voice. The most hateful of voices is the donkey’s bray.’ (Surah Luqman, 19)
Like panicked donkeys. (Surat al-Muddaththir, 50)
HORSE
To mankind the love of worldly appetites is painted in glowing colours: women and children, and heaped-up mounds of gold and silver, and horses with fine markings, and livestock and fertile farmland. All that is merely the enjoyment of the life of this world. The best homecoming is in the presence of Allah. (Surah Al ‘Imran, 14)
Arm yourselves against them with all the firepower and cavalry you can muster, to terrify the enemies of Allah and your enemies, and others besides them whom you do not know. Allah knows them. Anything you spend in the Way of Allah will be repaid to you in full. You will not be wronged. (Surat al-Anfal, 60)
When swift horses, champing at the bit, were displayed before him in the afternoon, he said, “Truly do I love the love of good, with a view to the glory of my Lord,” - until (the sun) was hidden in the veil (of night). (Surah Sâd, 31-32)
Whatever booty from them Allah has given to His Messenger - and you spurred on neither horse nor camel in its acquisition, but Allah gives power to His Messengers over anyone He wills, Allah has power over all things. (Surat al-Hashr, 6)
By the charging horses panting hard, striking sparks from their flashing hooves. (Surat al-’Adiyat, 1-2)
HORSE, MULE AND DONKEY
And horses, mules and donkeys both to ride and for adornment. And He creates other things you do not know. (Surat an-Nahl,
CAMEL
He (Salih) said, ‘Here is a she-camel. She has a time for drinking and you have a time for drinking - on specified days. (Surat ash-Shu’ara’, 155)
Slurping like thirst-crazed camels. (Surat al-Waq’ia, 55)
Whatever booty from them Allah has given to His Messenger - and you spurred on neither horse nor camel in its acquisition, but Allah gives power to His Messengers over anyone He wills, Allah has power over all things - (Surat al-Hashr, 6)
Like a herd of yellow camels. (Surat al-Mursalat, 33)
When the camels in foal are neglected. (Surat at-Takwir, 4)
Have they not looked at the camel - how it was created? (Surat al-Ghashiyya, 17)
And the Messenger of Allah had said to them,’This is the she-camel of Allah, so let her drink!’ But they denied him and they hamstrung her, so their Lord crushed them for their sin and flattened them. (Surat ash-Shams, 13-14)
BIRD
As a Messenger to the tribe of Israel, saying: ‘I have brought you a Sign from your Lord. I will create the shape of a bird out of clay for you and then breathe into it and it will be a bird by Allah’s permission. I will heal the blind and the leper, and bring the dead to life, by Allah’s permission. I will tell you what you eat and what you store up in your homes. There is a Sign for you in that if you are believers. (Surah Al ‘Imran, 49)
Remember when Allah said, ”Isa, son of Maryam, remember My blessing to you and to your mother when I reinforced you with the Purest Spirit so that you could speak to people in the cradle and when you were fully grown; and when I taught you the Book and Wisdom, and the Torah and the Injil; and when you created a bird-shape out of clay by My permission, and then breathed into it and it became a bird by My permission; and healed the blind and the leper by My permission; and when you brought forth the dead by My permission; and when I held back the tribe of Israel from you, when you brought them the Clear Signs and those of them who disbelieved said, “This is nothing but downright magic”. (Surat al-Ma’ida, 110)
There is no creature crawling on the earth or flying creature, flying on its wings, who are not communities just like yourselves - We have not omitted anything from the Book - then they will be gathered to their Lord. (Surat al-An’am, 38)
Do you not see that everyone in the heavens and earth glorifies Allah, as do the birds with their outspread wings? Each one knows its prayer and glorification. Allah knows what they do. (Surat an-Nur, 41)
We gave Dawud great favour from Us: ‘O mountains and birds! Echo with him in his praise!’ And We made iron malleable for him. (Surah Saba’, 10)
And also the birds, flocking together, all of them turned to Him. (Surah Sâd, 19)
And any bird-meat they desire. (Surat al-Waqi’a, 21)
Have they not looked at the birds above them, with wings outspread and folded back? Nothing holds them up but the All-Merciful. He sees all things. (Surat al-Mulk, 19)
Unleashing upon them flock after flock of birds, (Surat al-Fil, 3)
CROW
Then Allah sent a crow which scratched at the earth to show him how to conceal his brother’s corpse. He said, ‘Woe is me! Can I not even be like this crow and conceal my brother’s corpse?’ And he became one of those who suffer bitter remorse. (Surat al-Ma’ida, 31)
QUAIL
And We shaded you with clouds and sent down manna and quails to you: ‘Eat of the good things We have provided for you.’ They did not wrong Us; rather it was themselves they were wronging. (Surat al-Baqara, 57)
We divided them up into twelve tribes - communities. We revealed to Musa, when his people asked him for water: ‘Strike the rock with your staff.’ Twelve fountains flowed out from it and all the people knew their drinking place. And We shaded them with clouds and sent down manna and quails to them: ‘Eat of the good things We have provided you with.’ They did not wrong Us; rather it was themselves they wronged. (Surat al-A’raf, 160)
Tribe of Israel! We rescued you from your enemy and made an appointment with you on the right hand side of the Mount and sent down manna and quails for you. (Surah Ta Ha, 80)
FISH
But when they reached their meeting-place, they forgot their fish which quickly burrowed its way into the sea. (Surat al-Kahf, 61)
He (Musa’s servant) said, ‘Do you see what has happened? When we went to find shelter at the rock, I forgot the fish. No one made me forget to remember it except Satan. It found its way into the sea in an amazing way.’ (Surat al-Kahf, 63)
Then the fish devoured him (Yunus) and he was to blame. (Surat as-Saffat, 142)
LION
Like panicked donkeys fleeing from a lion? (Surat al-Muddaththir, 50-51)
ELEPHANT
Do you not see what your Lord did with the Companions of the Elephant? (Surat al-Fil, 1)
GNAT
Allah is not ashamed to make an example of a gnat or of an even smaller thing. As for those who believe, they know it is the truth from their Lord. But as for those who disbelieve, they say, ‘What does Allah mean by this example?’ He misguides many by it and guides many by it. But He only misguides the deviators. (Surat al-Baqara, 26)
BEE
Your Lord revealed to the bees: ‘Build dwellings in the mountains and the trees, and also in the structures which men erect. Then eat from every kind of fruit and travel the paths of your Lord, which have been made easy for you to follow.’ From inside them comes a drink of varying colours, containing healing for mankind. There is certainly a Sign in that for people who reflect. (Surat an-Nahl, 68-69)
LOCUST
They will emerge from their graves with downcast eyes, like swarming locusts. (Surat al-Qamar, 7)
So We sent down on them floods, locusts, lice, frogs and blood, Signs, clear and distinct, but they proved arrogant and were an evildoing people. (Surat al-A’raf, 133)
SPIDER
The metaphor of those who take protectors besides Allah is that of a spider which builds itself a house; but no house is flimsier than a spider’s house, if they only knew. (Surat al-’Ankabut, 41)
WORM
Then when We decreed that he (Sulayman) should die, nothing divulged his death to them except the worm which ate his staff; so that when he fell down it was made clear to the jinn that if they had truly had knowledge of the Unseen they need not have stayed there suffering humiliating punishment. (Surah Saba’, 14)
SNAKE
He threw it down and suddenly it was a slithering snake. (Surah Ta Ha, 20)
Throw down your staff.’ Then when he saw it slithering like a snake he turned and fled and did not turn back again. ‘Have no fear, Musa. In My Presence the Messengers have no fear - (Surat an-Naml, 10)
Throw down your staff!’ Then when he he saw it slithering like a snake he turned and fled and did not turn back again. ‘Musa, approach and have no fear! You are one of those who are secure. (Surat al-Qasas, 31)
FLY
Mankind! An example has been made, so listen to it carefully. Those whom you call upon besides Allah are not even able to create a single fly, even if they were to join together to do it. And if a fly steals something from them, they cannot get it back. How feeble are both the seeker and the sought! (Surat al-Hajj, 73)
METAPHORS WITH anImals
The likeness of those who disbelieve is that of someone who yells out to something which cannot hear - it is nothing but a cry and a call. Deaf - dumb - blind. They do not use their intellect. (Surat al-Baqara, 171)
We created many of the jinn and mankind for Hell. They have hearts they do not understand with. They have eyes they do not see with. They have ears they do not hear with. Such people are like cattle. No, they are even worse! They are the unaware. (Surat al-A’raf, 179)
Allah will admit those who believe to Gardens with rivers flowing under them.Those who disbelieve have their enjoyment, eating as cattle eat, but the Fire will be their final residence. (Surah Muhammad, 12)
Likening to Monkeys and Pigs
You are well aware of those of you who broke the Sabbath. We said to them, ‘Be apes, despised, cast out.’ (Surat al-Baqara, 65)
Say: ‘Shall I tell you of a reward with Allah far worse than that: that of those whom Allah has cursed and with whom He is angry - turning some of them into monkeys and into pigs - and who worshipped false gods? Such people are in a worse situation and further from the right way.’ (Surat al-Ma’ida, 60)
Likening to Dogs
If We had wanted to, We would have raised him up by them. But he gravitated towards the earth and pursued his whims and base desires. His metaphor is that of a dog: if you chase it away, it lolls out its tongue and pants, and if you leave it alone, it lolls out its tongue and pants. That is the metaphor of those who deny Our Signs. So tell the story so that hopefully they will reflect. (Surat al-A’raf, 176)
Likening to Donkeys
Like panicked donkeys. (Surat al-Muddaththir, 50)

…my uncle leòn found donkey voices sweet and played the cantina
for them in the evening so they would be soothed. the nauatlaca
basques treated them kindly, and the greek word, onager, from whence
donkey, goes back to the nauatl word, onaqui(N)=(he)who laughs, or,
she who has one on(english slang). i don’t understand why their voice is hateful. does not allah, alaua/oalauh(N)=annoint, have a sense of humor? and what does he say of elephants/oliphants/ollin
pantli(N)=the holy flag/family of animals? and i would hate to eat just any bird, the buzzard is my totem animal, the scribe and symbol
of old age. another question: what does it profit(pun)allah to
curse so much, does he not believe in redemption for one’s sins.
he seems quite unforgiving, like the desert he comes out of,
hot, windy, and the enemy of life. but i have a vision for his
people: they should be in charge of the world’s water and the
world’s airlines, for they have 400 names for water and are experts
on this liquid just as the eskimos know snow, and they sit on huge
petro-chemical reserves, control the price of combustibles, therefore are in a position to make or break the airways, which,
in other hands than theirs lose money and burden the individual
nations who run them. water and air are a great responsibility
but i have every confidence your people led by your stern prophet
will be equal to this delicate and at once harshly challenging task
for the world at large. good luck, and may you prosper as citizens
of the new world all faiths large and small share. tks.
