Open encyclopedia reference
Dipturus trachyderma, the roughskin skate, is a skate belonging in the family of Rajidae and the genus Dipturus. They live between the Southeast Pacific and Southwest Atlantic Ocean. They are one of the largest marine skates reaching up to about 265 cm (104 in) in length. They are also known for their slow growth, long life span that ranges to around 25 years and late sexual maturity at around 15 to 17 years old. Due to their slow growth and late sexual maturity, D. trachyderma is vulnerable to exploitation.
