Distribution and Population
In Canada, Pighead Pricklebacks are found in the Beaufort Sea. This species is not common in Canada.
Pighead Pricklebacks seem to prefer deep saline waters with sandy and silty bottoms; spawning occurs in shallow water.
Information on the general biology of the Pighead Prickleback is limited.
Perturbations in the nearshore habitat used for spawning could have limiting effects on the populations of Pighead Pricklebacks.
