The Atlantic sharpnose shark is a small shark in comparison to others. The Atlantic sharpnose shark's maximum species length is known to be about 110–120 cm (3.6–3.9 ft). Although its average adult size tends to be about 91.4–99 cm (3.00–3.25 ft).
Baby dogfish, also known as pups, found near Newfoundland had an average of 1.1 cm/month and 24 month pregnancy period, while a warmer area such as Massachusetts had an average of 1.3 cm/month and 20-22 month pregnancy period. [27] The sexual maturity of a dogfish is hard to determine because it varies anywhere from 10–30 years.
In the course of pregnancy, the embryo's average rate-of-growth is 1.40 cm (0.55 in) per month until birth, when the shark pups are 40–60 cm (16–24 in) long, therefore, the frilled shark's gestation period can be as long as 3.5 years; [16] [15] at birth, a frilled shark's litter comprises 2–15 pups, with an average litter comprises 6.0 pups.
Sharks living in cooler water have slower metabolisms than sharks in warmer water housings and therefore require less food. [7] The most common staple food provided to captive sharks in home aquaria is frozen fish. [7] The freezing process used to store foods for sharks often results in the food items losing nutrient value. [7]
Pacific angel shark pups are born from March to June in deep water; generally 180 to 300 feet (55 and 90 metres); possibly to protect the pups from predators. [ 6 ] Angel sharks usually reside in depths of 1–200 metres (3.3–656.2 ft) and can be seen on muddy or soft benthic substrata where they can easily blend in as they lie in wait.
