* Seasonal migrations: They do exhibit some seasonal movement, primarily driven by water temperature changes and the availability of prey. They might shift between deeper and shallower waters depending on the season.
* Short-distance movements: These migrations are usually short-distance, typically within a few hundred miles of their usual habitat.
* Local movements: Dogfish sharks can also make local movements in response to food availability or changes in current conditions.
It's important to note that the specific migratory patterns of dogfish sharks can vary depending on the species and the geographic location.
Here's a breakdown of some known migration patterns for different dogfish shark species:
* Spiny dogfish (Squalus acanthias): This species is known to migrate vertically between shallow and deep waters, and they can also move horizontally across the Atlantic Ocean. However, these movements are usually short-distance and within a particular geographic area.
* Smooth dogfish (Mustelus canis): This species exhibits some seasonal movements in the western Atlantic, migrating southward during the winter and northward in the spring.
Overall, while dogfish sharks can migrate, their movements are generally short-distance and localized, compared to the extensive migrations of other shark species.
