It’s moth week and I can’t be out!!
The fish family Pegasidae, aka sea moths, includes just five species (placed in two genera) but is represented in temperate and tropical coastal zones throughout the Indo-Pacific. All sea moths are small (no more than than ~180 mm total length), benthic (bottom-dwelling), and very well camouflaged. Seamoths have modified pelvic fins that allow them to “walk” across the sea bottom where they live.
A curious behavior seen in these fish (almost in Eurypegasus draconis) is that they sheds their skins in one piece, probably every one to five days, a process described in some detail by Herold and Clark (1993). These researcher also discuss evidence suggesting monogamy in this species, as well as other aspects of social and reproductive behavior.
