In the Arabian Sea, the biomass of lanternfishes is particularly high, but dominated by only a few species. Much of the high production of the Arabian Sea is channelled via zooplankton to the stock of lanternfishes due to the low abundance of competing small pelagic fish.

#CrabAZ never ignores memes. M is for Macrocheira. This is both the largest arthropod alive (3.8 m or 12 ft leg span, only males are this extreme) and the only living species in its family. Mainly found in Japanese waters up to 600 m depth. (Yes we know it's Thursday, sorry) ๐Ÿฆ€๐Ÿงช๐Ÿฆ‘

Meme of Japanese spider crab. It's a red crab with cartoonishly long claws on a black background.
