Let's dive into the fascinating world of dog fish species. There are over 120 species of dog fish, ranging in size, shape, and color.

Some of the most common types of dog fish include the spiny dog fish, which has a distinctive spiny skin, and the smooth dog fish, which has a smooth, scaleless body.

One notable characteristic of dog fish is their ability to produce a toxic mucus, which they use for defense. This mucus can be irritating to humans and other predators.

From the deep-sea habitats of the spiny dog fish to the coastal waters of the smooth dog fish, these creatures have adapted to various environments.

Types of Dogfish

Dogfishes and spurdogs are fascinating creatures, and there are many different types to learn about. Some examples include the blacktailed spurdog, which can be found in the western Pacific Ocean near New Caledonia.

The combtooth dogfish is another interesting species, found in the eastern Pacific Ocean. Its habitat is quite different from the blacktailed spurdog's.

  • Blacktailed spurdog (Squalus melanurus)
  • Combtooth dogfish (Centroscyllium nigrum)

Lesser Spotted

The Lesser Spotted Dogfish is a small and shark-like fish with a white or light coloured under-belly and tan or sand coloured flanks.

They are covered in a variety of darker, small spots, and some individuals may be almost black if taken from heavily weeded areas.

Their nasal flaps meet at the mouth, which helps distinguish them from their larger cousins, the Greater Spotted Dogfish.

You can find Lesser Spotted Dogfish almost anywhere in Irish salt-water, from clean sand to broken reef or pure rock and kelp.

They are commonly caught by competition anglers, but often loathed by pleasure anglers who prefer to catch bigger fish.

Habitat

Dogfish are found in various habitats around the world, including coral reefs, rocky areas, and even the deep sea.

Some dogfish species, like the lesser spotted catshark, prefer to live in shallow waters with low visibility, where they can ambush prey.

Dogfish have been known to inhabit areas with a mix of sand and rock, which provides them with the perfect place to hide and hunt.

The spiny dogfish is commonly found in temperate and tropical waters, where it can be found swimming near the seafloor.

Dogfish often live in close proximity to other marine animals, such as rays and sharks, which can be a result of their similar habitats and feeding habits.

In the deep sea, dogfish have been found living in areas with near-freezing temperatures and total darkness, where they have adapted to survive without light.

About the Species

The Atlantic spiny dogfish fishery operates from Maine to Florida and from inshore to offshore waters on the edge of the continental shelf.

The spiny dogfish fishery uses predominantly bottom gillnets, with lesser amounts caught by trawls and hook gear.

There is little consumer demand for spiny dogfish in the United States.

U.S. wild-caught Atlantic spiny dogfish is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.
