I had no idea crab eyes really stuck up like that. I thought that was just in cartoons. I’m a Pacific Coast girl, and I swear I’ve never seen that in any Aquarium, nor at the tide pools, nor at the live seafood tank on the pier. Honestly, you never know what you will learn on FR.
Depends on the type of crab. The really prounounced “eyes on stalks” appearance tends toward those species that spend a lot of time in the tidal wash on a beach. The larger ones that spend most of their time submerged don’t look quite so comical. I recall as a kid almost stepping on a huge blue crab while wading out into the inlet at low tide, I’d say those are more menacing than comical, lol, but then again it scared the crap out of me.
