Bignose Shark Fun Facts
What does a bignose shark look like?
Bignose sharks are heavy-bodied and have a long, broad, and pointed snout, well-developed nasal flaps, large round eyes protected by nictitating membranes. These membranes help to keep sand or any tiny particles out of their eyes. They also have a broad and curvy mouth, five pairs of gill slits, rows of sharp triangular teeth. There are 14-16 rows of teeth on each side. The pectoral fins are moderately long with have black tips, a pair of dorsal fins, and an interdorsal ridge. An interdorsal ridge is the lifted of skin between the first dorsal fin and the second dorsal fin. The first dorsal fin is tall, sickle-shaped, and originates near the pectoral fins, whereas the second dorsal fin is wider with a short free rear tip, and is placed near the anal fin. The pectoral fins are slightly darker than the other features and the caudal fin is placed far on its body. These sharks are gray from above and white below. Younger sharks have a rounded and shorter snout but have the same coloration, and are 28–35 in (70–90 cm) in length.
