Mysterious and interesting things, first read about them after going scuba diving and seeing a few of there barely-there diaphanous whisps of creatures, with rippling iridescent spines up their sides.
Amazing to learn they were cilia refracting the light, not chemical bioluminescence, and that despite appearances they are absolutely not jellyfish!
And they are nor just bioluminiscent, almost all are strongly bioluminiscent (via chemicals). Cilia adds motion to the spectacle ad maybe can change its color, but they definitely can turn on and off the lights. Many of this animals live in places without much light and do a vertical migration at night, each night. All are carnivores of small preys and is assumed also that they use light to lure its preys near their sticky longlines
Its lights can be used by us to detect toxics in the water. They react to contaminants making the luminiscence much brighter. Just as if they were alarmed and trying to warn other.
I wonder just now, if there is a hidden language there, like with bees dancing to communicate with other bees. Most probably. Who knows.
Steven Haddock, a marine biologist who studies ctenophores
Interesting case of nominative determinism.
Haddock is a bilatarian species though :P
But yes, the I suppose a call to study ocean creatures can be more compelling with that’s name.
I imagine Steven Hydra was taken.

So, they actually look like that as in the first video (gliding ribbon-like thing)? I can't tell if it's an animation or not, but it's so cool!
Yep. This is their normal aspect.
