Well, I was just thinking about an old idea of mine called the Octopod. It would have 8 tentacles (hence the "octo" part,) each with a claw on the end, 8 eyes (one at the base of each tentacle) and a mouth in the centre. It would cling to rocks along the coastline, mouth shut, eyes open and wait for a crab/fish/bathing mudokon to come by, and suck them in. How's that.
