Technically, they are called Costasiella kuroshimae…
… but their informal name is ‘Leaf Sheep.’ They’re one of the only animals in the world that can perform photosynthesis; they eat algae, suck out the chloroplasts, and incorporate them into their own bodies.
It’s a phenomenon known as functional kleptoplasty, if you want to get all geeky and technical about it (which I do). Basically it means they’re kind of like solar-powered slugs!
According to research from Charles Paxton, fisheries ecologist and statistician at Scotland’s University of St. Andrews, published in the Journal of Zoology this month, the giant squid could grow to reach as much as 65 feet. But even that is a “conservative analysis,” as size could protect against their #1 predator.
This is a picture of a humpback that placed a seal onto its upturned belly in order to move it towards safety. When the seal started to slip off, the whale pushed it back on with its fin, then swam until the seal could get itself onto the ice.
Some researchers think the whales engage in this behavior because it’s how they protect their own calves, but they aren’t sure why they would continue the fight knowing it wasn’t another whale.
Jellyfish are soft because they are 95% water and are mostly made of a translucent gel-like substance called mesoglea. With such delicate bodies, jellyfish rely on thousands of venom-containing stinging cells called cnidocytes for protection and prey capture.
