Range and Identity
The inventory identity is Squalus acanthias. Modern accounts distinguish the North Pacific Spiny Dogfish as Squalus suckleyi. A worldwide dogfish summary or an old Pacific record should not automatically supply the range, maximum length or mass for this species.
Habitat and Behavior
Fish occupy both inshore and offshore waters, commonly near the bottom but also in midwater or near the surface. Schools can separate by size and sex. Seasonal movement is associated with water conditions, so a single coastal observation does not define year-round habitat.
Food and Life History
Foods include crustaceans, squid, jellyfish and schooling fishes, with prey changing as fish grow. Females bear live young after a pregnancy of roughly eighteen to twenty-four months. The Atlantic agency account reports females reaching four feet, without specifying a formal length convention; uncertain worldwide maxima are not substituted.
Field Note
Keep ocean region and scientific identity together. They prevent Pacific measurements from being mistaken for records of the Atlantic-associated species described on this page.
