Cuttlefish can disguise themselves as coral to catch prey off guard

Who will eat who?
Well I certainly hope that it will be you
For you see the cuttlefish is hungry too

Cuttlefish is hungry but I am hungry and bored and have enough time to set a trap. Mwahaha. Say goodbye to your friend
ps. You are invited to calamari dinner. Tonight we are serving cuttlefish. Freshly caught

I thought calamari was octopus?
