Whoever named the giant isopod didn’t expend too much energy coming up with that name. In short, it’s a giant isopod, a big giant crustacean that crawls around in
the depths of the Atlantic and Indian oceans.
French zoologist Alphonse Milne-Edwards was the first to describe the genus in 1879 after his colleague Alexander Agassiz collected a juvenile male B. giganteus from the Gulf of Mexico; this was an exciting discovery for both scientists and the public, as at the time the idea of a lifeless or “azoic” deep ocean had only recently been refuted by the work of Sir Charles Wyville Thomson and others. No females were recovered until 1891.
Giant isopods are of little interest to most commercial fisheries owing to the typical scarcity of catches and because ensnared isopods are usually scavenged beyond marketability before they are recovered. The species are noted for resemblance to the common woodlouse or pill bug, to which they are related. The few specimens caught in the Americas and Japan with baited traps are sometimes seen in public aquariums.
