Tope
(Galeorhinus galeus)
Overview
Tope can reach an age of 55 years and grow to about 200cm. As with several other sharks, tope has a low population productivity, relatively low fecundity and protracted reproductive cycle, making it highly vulnerable to exploitation. Tope is an aplacentally viviparous shark. Aplacental viviparity is a form of egg development in which the eggs hatch while still inside the uterus but the developing young aren't nourished by a placenta. Aplacental viviparity used to be referred to as (No Suggestions). Gestation or pregnancy lasts approximately one year. Mating occurs in January. The Bristol Channel and south-western North Sea are considered to be important nursery grounds for the species. It is found at depths down to 500 m. Some have been known to migrate large distances but this is not a feature of the species as a whole, as many stay in local waters.
