The bighead searsid (Holtbyrnia anomala) is a species of tubeshoulder fish. [2] [3]
It maximum length is 25 cm (9.8 in). [4] Its head is large, making up over a third of the fish's length. It has 25–31 gillrakers; 5–11 pyloric caecae. The snout is pointed, with premaxillary tusks pointing forward. [5]
It is dark red in colour. [6] Its photophores are rudimentary (except for the shoulder organ), hence its specific name anomala ("unusual"). [7] [8] [9]
