Filetail Catshark - Parmaturus Xaniurus
Filetails are easily recognized by the rows of outsized and rough scales
that cover the leading edge of the upper caudal fin. The inside of the
mouth is pale while the dorsal surface is a grayish brown with a lighter
underside. Reaches 24 inches long.
The peppered shark also has a rough leading edge to its upper caudal but
the inside of its mouth is dark gray. A common species in deeper waters off
of California and the Monterey bay. Travels in gender segregated schools of
thousands. Common bycatch for black cod long-liners and drag boats.
Filetails are yet another example of a poorly studied shark of which little
is known. They appear to feed on small squid, octopus, and crustaceans.
Development is oviparous. Filetails reach maturity at about 16" inches.
Egg cases are a tan color.
