Where are the lobsters gills?

Lobsters use gills to breathe. Their gills are blood-filled, feathery organs which extract oxygen from water. The gills can be found at the base of the lobster’s legs. Blood travels from the gills to other parts of the body, providing oxygen along the way.

What are lobster tentacles for?

The four small antennae on the front of their heads are used to “smell” their food or chemicals in the water. The tiny sensory hairs along their legs are used to “taste” their food. Lobsters keep their antennae and eye stalks moving constantly to search for food and to watch for enemies.
