The dogfish shark (Squalus acanthias) was the first shark species studied since it was accessible for research purposes at the Mount Desert Marine Biological Laboratory. In addition, large numbers of dogfish are harvested annually for consumption [ 2 ] and could provide sufficient tissue for extraction during the early stages of compound ...
Dogfish sharks use their strong jaw and sharp teeth to consume their prey. The spiny dogfish has broken several records in the areas of migration and gestation. This shark tends to be a highly migratory species: one shark was recorded as travelling 8,000 km (5,000 miles) after being tagged in Washington state, United States, and found again ...

Trodusquemine is an aminosterol (polyamine steroid conjugate) that inhibits protein tyrosine phosphatase 1B (PTP1B) activity. [1] The compound exhibits broad-spectrum antimicrobial activity [2] and numerous regenerative, neuroprotective, anti-atherosclerotic, antitumor, antiangiogenic, antiobesity, and anxiolytic properties.

Sleeper sharks are a poorly studied [15] deep-sea shark found in all oceans. [16] They contain antifreeze to survive in cold temperatures, and may feed on colossal squid. In Iceland, they are hunted for food. They are allowed to rot for months until the poisonous antifreeze degrades, and they are safe to eat. [17] Squalidae: Dogfish sharks: 3 31

The Portuguese dogfish (Centroscymnus coelolepis) or Portuguese shark, is a species of sleeper shark of the family Somniosidae. This globally distributed species has been reported down to a depth of 3,675 m (12,057 ft), making it the deepest-living shark known. It inhabits lower continental slopes and abyssal plains, usually staying near the ...
