Keluphosphera

Keluphosphera (from ancient Greek κέλυφος (kéluphos) 'shell', and σφαῖρα (sphaîra) 'ball') is a subphylum of the phylum Hexokelupha.

Description
Keluphospherans have a gut that small animals and particles are pulled into by their tentacle-like protrusions. They can move very slowly through a kind of crawling, having many small feet that pull them along the lake bed and rocks. They have a calcified shell that protects their innards from the sun and predators.

Keluphospherans have a ring of small, simple eyes around the mouth, allowing them to sense when something is overhead.

One class of keluphospheran have evolved to produce toxins which paralyze prey when grasped, allowing them to eat larger targets without being damaged.
