The Pacific sharpnose shark (Rhizoprionodon longurio) often migrates along the Pacific coast of Mexico. They are most commonly caught in the artisanal fishery of Mazatlán. When a large sample of Pacific sharpnose sharks were observed scientists concluded that this type of shark was a "viviparous shark of small size which is born at an average length of 31 cm." Their gestation period is between ten and eleven months. There was found to be no statistical relationship between the number of embryos to the average length as a result of scientific research. Specialists David Corro, Leonardo Castillo Geniz and J. Fernando Marquez-Farias, found that the sex ratio of this specific Shark is one to one with the average number of embryos per female, being around 7.4. Wikipedia →
