Do ctenophores have the same homeoviscous adaptation to compensate for extreme pressure? Looking to lipids. These cold adaptations often come down to lipids–or fats.

If ctenophores arose first, it “implies that either sponges have lost a massive number of features, or that the ctenophores effectively evolved them all independently,” says Graham Budd, a ...

Ctenophores’ unique features, including their distinct nerve and muscle systems, suggest these traits may have evolved independently in early animal lineages.

A multi-institutional team that includes researchers from the University of Delaware, University of California San Diego and Monterey Bay Aquarium Research Institute (MBARI), among others, published a ...

Comb jellies, technically known as ctenophores, are one of the weirdest creatures on Earth. They appeared in the seas over half a billion years ago and have maintained to the present day the comb ...

“We know that comb jellies (aka: ctenophores) are sentient in that they can sense their surroundings to find food and change the direction of their swimming if they bump into something,” study ...

Ctenophores, also called comb jellies, are ghostly-looking bags of goo whose crystalline combs—structures they use like tiny oars to move through water—refract light into rainbows.

Mnemiopsis leidyi, also known as sea walnuts, comb jellies or ctenophores, are a type of animal similar to jellyfish that eat plankton and have translucent, bell-shaped bodies, according to a case ...

They are known to eat other ctenophores and salps, while fish, turtles, marine mammals, and more dine on comb jellies. Comb jellies also appear to be able to fuse together.

Ctenophores’ unique features, including their distinct nerve and muscle systems, suggest these traits may have evolved independently in early animal lineages.
