This species reaches a maximum length of 9.8 feet (3 metres), and can weigh as much as 370 pounds (168 kg). It is found in [[tropical]] and [[subtropical]] regions, along the edges of continental shelves and insular slopes, at depths of up to 1,410 feet (430 metres). == Description== [[ Image:Carcharhinus_altimus_drawing.png|thumb|left|250px| A drawing of the Bignose shark ]] The Bignose shark is large and slim with a long, wide and bluntly-pointed snout from which it gets its name. It has well developed flaps on the [[nose]], which are clearly visible. The interdorsal ridge (ridge between the two [[dorsal fin]]s) is high and very visible. The [[pectoral fin]]s are long and straight. The first dorsal fin has a bluntly-pointed tip, and is located above or behind the pectoral fins. The [[anal fin]] is slightly behind the second dorsal fin. Bignose sharks are similar in looks to the [[Night shark]]s, however the Night sharks have a second dorsal fin which has a free rear tip that is at least twice as long as the height, while the Bignose shark's second dorsal fin has a short free rear tip. The Bignose shark has a grey coloured body with no visible markings other than being white below and having pectoral fins which have black tips. The tips of all the [[fin]]s, other than the [[pelvic fin]]s,
