Jaggedhead gurnard (Gargariscus, Armored searobins or armored gurnards)
Photographer and Fisherman: Roman Fedortsov
The reason they call this group “sea robins” is because the .ore commonly encountered species look more like this one:
The armored ones live deeper, and they also come in weirder shapes!
the other thing is some have little crawly leggies from modified fin rays. and they can grunt!
