Diplacanthus crassisimus Duff

Small to medium sized acanthodian with big, ribbed spines. On the belly it also has intermediate spines, small paired spines between the pectoral and pelvic spines.

It is very common in the Sandwick Fish Bed. Probably not eaten much by other fish since it is very spiny!

In literature the species name striates is also used.
