Enypniastes eximia: The Swimming Sea Cucumber



From NOAA website:

“The deep seafloor is generally considered to be quite food poor away from the seep areas. This leads to a series of adaptations in the animals living there. Here we see a swimming sea cucumber evolved from benthic animals that feed upon the sediment. This one is capable of swimming over the seafloor using highly-modified feet that have turned into fins. If you look closely you can see the mud-filled gut inside the semi-transparent animal. When it finds a suitable spots it will drop to the bottom to feed on the sediment and then swim away again to find another suitable spot.

  1. Enypniastes Eximia:

    "Species in this genus have developed webbed swimming structures at the front and back of their bodies which enable them to swim up off the surface of the sea floor and to journey as much as 1000m up into the water column. This is thought to help the animals move to new feeding grounds and avoid predators.

    When Oceaneering ROV pilots saw and photographed the creature at 2500m depth they named it “The Headless Chicken Fish.”"

    It's known as the "Deep Sea Spanish Dancer" and uses a unusual defense mechanism: when attacked, its grainy skin lights up and detaches, sticking to the aggressor. Finding its face plastered with a sticky, bioluminescent mask that it cannot shake off, the would-be predator becomes the vulnerable prey."

  2. 気持ち悪い…でもちょっと綺麗かも。深海には不思議な生物がいっぱいだね!

  3. It is so silly for you to think that such a creature could have evolved such capabilities as the sea cucumber has. It could not have survived without being made like it was from the start. This is a self-evident truth.

  4. Thanks. I didn't mean to refer to it as a fish; just didn't know what to call it. At least now I know that it's an echinoderm.
