I live in and around vents Preferred temperature: up to 15° C Description: up to 30-60 mm; pale white Food: scavenge on limpets, polychaetes, bacteria and other dead animals Facts: blind; fierce predators as well as scavengers

Scientific name: Munidopsis sp

What animal am I ?

• squat lobster

• tubeworm

• spaghetti worm

• microbes

These two-foot long white fish are top predators around vents. They eat everything from tubeworms to shrimp. Despite their huge appetites, these fish are slow and lethargic. They spend a lot of time floating around clumps of tube worms and mussels
