Q. Do lobsters have lungs? If not, how do they survive the long drive from Maine perched on a pile of seaweed in the cooler?

A. Lobsters have gills, not lungs, said Diane Cowan, senior scientist at the Lobster Conservancy in Friendship, Me. The gills “remove oxygen from seawater and from the air, too, as long as the gills remain cool and moist,” she said.

Lobsters have five pairs of gills, each attached to one of their 10 legs, including the claws, the big front pair.
