5 shark species that live in the Long Island Sound off Connecticut - CT Insider

BIDDEFORD, ME - JUNE 23: Dave Johnson, a professor in the medical school at the University of New England, releases a spiny dogfish, a species of shark, back into the water in the Gulf of Maine after James Sulikowski, a professor of Marine Sciences at UNE, performed an ultrasound on the pregnant fish Thursday, June 23, 2016. Sulikowski, who found the small sharks on the Tantas Ledge about 9 miles off the coast of Biddeford, will be featured on Discovery Channel's "Shark Week" this coming Sunday for using a similar technique on much larger tiger sharks. Sulikowski is pioneering the ultrasound method of research. Previously, scientists would have to kill the shark to gain as much information as they now can through ultrasound.

The spiny dogfish shares many similarities to the smooth dogfish in that the species typically feeds on crustaceans at the bottom of the ocean. It has two spines, and when threatened, can arch its back in order to secrete venom into a predator, according to Oceana. Spiny dogfish have sharp teeth as well, but they are not considered a threat to humans.

Female spiny dogfish have a gestation period of 18 to 24 months, which is one of the longest gestation periods for any animal with a vertebrae, according to Oceana.  

Like with the smooth dogfish, catching spiny dogfish does not require a speciality license. There is also no minimum length or creel limit for catching this shark.
