Voigtmann's Reef Lobster

Found singly, during the day, hiding in caves and crevices, over shallow, rocky reef slopes.
They feed nocturnally on crustaceans, detritus, fish, and invertebrates.
Widespread Tropical Atlantic Ocean, Caribbean, Indo-Pacific

These are some of the smallest lobsters.

Lobsters live in caves and crevices during the day, often several together, coming out at night to feed.
Sometimes caught in the torches of divers where they scuttle off back into the dark.
They do not have true claws, the soft and flexible tail is used for swimming rapidly backwards, for short distances to get away from danger.
