Special thanks for the first photo of Meiacanthus luteus to Rudie H. Kuiter, Australia.
The Yellow fangbelly lives endemic to northern Australia from the North West Shelf, Western Australia, to Masthead Island, Great Barrier Reef, Queensland, the fangbelly inhabits turbid coastal reefs in a depth range of 0 to 35 meters.
The Gold-stripe Harptail Blenny is a white blenny with a dark brown to black midlateral stripe running from the snout tip through the eye to the caudal-fin base, a dusky to dark brown stripe from above the eye running along the dorsal-fin base, with bright yellow coloration on the head and body between the two stripes.
This fangblenny has grooved dentary canines with associated buccal glands containing a toxin!
These poisonous canines provide considerable protection from predators allowing them to feed over a wide area including in the water column.
