Of the 4 species in the genus Atelomycterus, the only one I've found that is easily obtainable is the coral catshark(marmoratus). It seems to be available online for around $170+. Though, aquatictech has them listed at $129, they don't keep them in stock, only pre-order. Thought I'd mention, they also have male and female Yellow-Spotted Stingrays in stock for $89+.
I'll keep checking on the other species for sales location/availability. This is a pic I found of a Coral Catshark:
