Caribbean sharpnose shark
|Caribbean sharpnose shark|
The Caribbean sharpnose shark, Rhizoprionodon porosus, is a requiem shark, and part of the family Carcharhinidae. It is found in the tropical waters of the western Atlantic Ocean and the Caribbean, between latitudes 28° N and 40° S, from the surface to a depth of 500 m. It can reach a length of about 1.1 m.
The maximum reported size for the Caribbean Sharpnose Shark is 110 cm ( 43 inches). The average adult size appears to be about 80-89 cm (31.5-35 inches). Both sexes seem to reach maturity at about 65-70 cm (25.6-27.5 inches) in length, and just over 2 years old. The life span is estimated to be about 8-10 years old. This species was once confused as being the same species as the Atlantic Sharpnose Shark - however difference in vertebra counts indicate that it is a separate species. Reproduction and litter size is similar to the Atlantic Sharpnose Shark.
