of Aplodactylus live on the coasts of Chile and Australia. They

are much compressed in body, with very oblique mouths, with 
fringed lips and, as befits their northern habitat, with a much 
increased number of vertebree. They bury themselves in sand 
under the surf, and the two species, Trichodon trichodon and 
Arctoscopus japonicus, range very widely in the regions washed 
by the Japan current. These species bear a strong resemblance 
to the star-gazers (Uranoscopus), but this likeness seems to be 
superficial only.
