Both are useless animals. I probably wouldn’t eat either because they feel, look, and smell weird, so they probably taste weird. If they made sounds I’m sure they would sound weird too. The only thing they are good for is filler footage in marine life documentaries and keeping little kids entertained at aquariums. And they are hardly even good at that -most kids want to touch small sharks and sting rays and stuff like that. They couldn’t care less about those stupid starfish and sea cucumbers.
Real cucumbers though, those are delicious. I’ll have those any day.
