Jellyfish Worm Shell

Thylacodes medusae

Jellyfish Worm Shell

Rather than crawling, this snail cements itself permanently to the seabed and grows a twisted, irregular tube instead of a coiled shell. It feeds by casting out sheets of mucus to trap drifting food, living in shallow subtidal water where it is sometimes gathered for the pot.
