hmm, looks like the conch may have something like eyelids that will iris closed...looks like the poor crab gets to watch whatever is eating him, all the way down
I cannot find a reference, but I believe conch eyes are pretty low resolution in terms of imaging. Many crabs have very finely compound eyes that image superbly. So yes the crab can probably see it in better detail.

Cuttlefish use an active optical spoofing method to disorient crabs that they are hunting - they make waves or stripes move from mantle to tentacle tips in a way that masks their slow approach to claw-bearing dinner.

I've caught crabs many times.....on the beach.....on the pier......on the dock.












Salt water crabs ...... you dirty minded bunch of........RIUers..


Never much cared for the taste of shallow water crab, but I love opies and king legs.

On one of my sister's domestic (Atlantic Seaboard) flights someone brought a cooler full of live soft-shells into the cabin.

So at the end of the flight, the intercom yodels

"Will the person who left the head flight attendant with a case of crabs please contact the gate staff?"

When I was 10-12, this was my favorite book, bar none. I had it near-memorized.



My big mistake is I thought "exhalant [siphon]" was a misspelling of "excellent", which meant the inhalant siphon was the one that was lousy. In a way, it did suck.

My first guess on Mr. Eyes was an olive shell, but those are conch eyes. Good catch!
If I'm not mistaken my Fathers book collection contains that one.
We amassed a beautiful (and substantial) shell collection starting in the Philippines & continued into S. Fla.

When I was ten, if you asked me where I wanted to live, the answer would have been "The Indo-Pacific". That is where almost all the cool shells came from.

Delaware beaches were almost entirely bivalves. There was the odd baby whelk or moon snail. I didn't really count slipper shells as univalves (incorrectly) because they weren't pretty univalves.
