They share membership in the same scientific phylum, a group of animals that have similar basic forms. Granted, it's a giantic phylum, the biggest in nature-Arthropoda, which includes insects, spiders and crustaceans. Lobsters, which are crustaceans, are hatched from eggs and undergo larval stages before reaching adulthood. So do mosquitoes. Lobsters see their world mosaic-style, through compound eyes.
Insects do, too.
Male lobsters find their mates by detecting the smell of chemicals given off by the females when their eggs are ready for fertilization. Same deal with insects. It's far from proven, of course. It's more likely, agree most scientific observers, that the lobsters have been snuffed out by more than a single culprit. More like a gang.
