Description
Its maximum width is 2 m (6.6 ft).[3]
Distribution
It is found in the eastern Atlantic from Portugal to the Central African coast[1] and in the eastern part of the Mediterranean Sea.[4]
Life cycle
They exhibit ovoviviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures.
