ANIMAL SPECIES:Sculptured Seamoth, Pegasus lancifer Kaup, 1861
The Sculptured Seamoth is a bottom-dwelling species that resembles a moth due to it's large horizontally directed pectoral fins and patchy colouring.
Identification
The Sculptured Seamoth has a depressed body that is encased in fused bony scale plates. It has a rostrum that is square in cross section. There is a single short based dorsal fin positioned opposite the anal fin. The pectoral fins are large and horizontally directed.
Three species of seamoths in two genera (Pegasus and Eurypegasus) occur in Australian waters. The two genera can be separated by a combination of characters including the number of tail rings (11 or more in Pegasus, 8 or 9 in Eurypegasus), deep pits behind the eyes (lacking in Pegasus, present in Eurypegasus), and the position of the eyes (not visible from below the fish in Pegasus, visible from below in Eurypegasus).

The Sculptured Seamoth is endemic to Australia. It is known from eastern Victoria, around the south of the country to south-western Western Australia.
