What on Earth is this?

The best

This appears to be some type of Pacific Sea Cucumber, but the follower who has been helping me can’t find a scientific name for it. It often shows up under the name ‘oh ikari’, but that doesn’t appear to be an official name. 

The weird frondy bits are oral tentacles, which are modified structures similar to the tube feet seen in other echinoderms like sea stars and sea urchins. The oral tentacles filter food particulates out of the water (algae, minute aquatic animals, or waste materials - yum) and are used to channel them into the animal’s mouth ones at a time.
