The strange looking Elephantfish can grow to 1.2m in length. It has a hoe-shaped structure on the snout.
The Elephantfish can be easily recognised by the hoe-shaped structure on the snout. Its head has a series of obvious sensory canals and pores. The pectoral fins are large, the first dorsal fin is preceded by a strong, serrated spine, and the caudal fin has a long upper lobe.
The body is silvery white, and sometimes has darker markings behind the eyes and on the fins.
It lives to depths of at least 200 m on the continental shelf
The Elephantfish occurs off southern Australia and New Zealand.
Other behaviours and adaptations
The Elephantfish has a skeleton made of cartilage. Sharks and rays also have cartilaginous skeletons. All three groups of fishes are classified in the class Chondrichthyes.
Life history cycle
In spring, females migrate into coastal bays and estuaries to lay their egg cases in sand and muddy substrates. The distinctively-shaped egg cases are sometimes found washed ashore after storms. They are up to 25 cm long, 10 cm wide, and take up to eight months to hatch.
It is caught commercially in New Zealand.
