Habitats of Dogfish

Dogfish: An Overview

Dogfish, also known as spiny dogfish, are an important species found in both the Atlantic and Pacific oceans. They are one of the most common and widespread species of shark, and can be found in a variety of habitats from shallow coastal areas to the deep ocean. Dogfish are known for their sharp spines and for the fact that they are ovoviviparous, meaning they give birth to live young.


Dogfish can be found in a variety of habitats, depending on their age and size. Juveniles are typically found in shallow coastal waters and estuaries, while adult dogfish can be found in deeper waters of up to 600 meters deep. Dogfish can also be found in temperate and tropical waters, although they are more common in colder waters. Dogfish can be found in a variety of habitats, including rocky reefs, sandy bottoms, seagrass beds, and even in kelp forests.

Distribution and Migration

Dogfish are found throughout the world’s oceans, from the Arctic to the Antarctic. They are highly migratory and can be found in both coastal and offshore waters. Dogfish migrate seasonally in search of food and warmer waters. They are also known to form large schools during their migrations, which can number in the tens of thousands.

Feeding Habits

Dogfish are opportunistic feeders, eating a variety of prey including fish, mollusks, crustaceans and even other sharks. They are known to use their sharp spines to capture prey, which can range in size from small fishes to large bony fish. Dogfish are also known to consume jellyfish and squid.


Dogfish are threatened by overfishing and bycatch. They are also threatened by habitat destruction, pollution, and climate change. The IUCN Red List lists the species as Near Threatened, and it is listed on Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).


Dogfish are protected in many parts of the world and there are a number of conservation initiatives in place to help protect them. In the UK, there are conservation areas for dogfish and a number of fishing restrictions in place to protect them. There is also a UK-wide Dogfish Survey, which collects data on the population and migration patterns of dogfish. In the US, there are also conservation efforts in place to protect dogfish and other shark species.


Dogfish are an important species in the world’s oceans, and they are threatened by a number of factors. It is important to protect them and their habitats in order to ensure that they remain a part of our oceans for generations to come. Conservation efforts, such as fishing restrictions and protected areas, are important in helping to protect this species.
