Jellyfish or jellies are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey.
A team led by researchers at the California Institute of Technology (Caltech) and Harvard University have built this remarkable display of modern bioengineering – a completely engineered jellyfish that blends both living and non-living parts, masterfully fitted together. Called the medusoid, this cyborg jellyfish was created using silicone and muscle cells from a rat’s heart, [...]
After a three year effort, researchers at Virginia Tech have successfully managed to create a silicone robot that functions underwater by mimicking the motion of a jellyfish. The robot can propel itself thanks to the heat-producing reactions catalyzed by its surface, and since it uses hydrogen and oxygen found in the water as fuel, the Robojelly can theoretically [...]
Federal regulators have designated almost 42,000 square miles of ocean as critical habitat for the leatherback turtles, the largest turtles in the world; even though this is a much welcomed initiative, the surface is far, far less than environmentalists and biologists were expecting. A haven for turtles This protected area is the first of its [...]
So, microorganisms and other humans aside, what do you think is the deadliest creature in animal kingdom? A snake, perhaps a lion or bear, a scorpion perhaps? Neah, not even close. The deadliest creature in the world is actually called a sea wasp. Specialists use the term ‘deadliest’ when they refer to venomous creatures, that [...]
The Nomura Jellyfish Nomura Jellyfish are a large species of Japanese jellyfish, that seems to be giving them some big headaches. They can grow up to 2 meters in diameter and usually weigh over 200 kilograms, going up to 220 in numerous cases and they spawn in the seas between China and Japan, invading the [...]
