Open encyclopedia reference
The tiger snout seahorse (Hippocampus subelongatus) or West Australian seahorse, is a species of fish in the family Syngnathidae. It is endemic to south-western Australia, where it occurs from the Abrolhos Islands to Rockingham. Its natural habitats are the edges of rocky areas, muddy bottoms and areas with murky water caused by high sediment load, around jetty pilings and moorings; it is often associated with sponges or sea squirts and frequently attaches itself to man-made objects. In the winter they move to deeper water.
