Colubraria muricata
Maculated dwarf triton, Giant false triton or Spotted Colubraria
Size: 4.5 - 11.5 cm
Depth: 5 - 20 m
Like most of this species, they are mainly nocturnal
and parasitise on sleeping fish, mostly parrotfish.
They use an extremely long proboscis to pierce the mucus covering
that the parrotfish produce at night for protection
and then pierce the fish to suck blood for nourishment.
