I get to use one of my favorite words to describe the reproductive habits of the Thresher Sharks. They are ovoviviparous! This means that they lay eggs, but they are laid inside the mothers body, and incubated there. The young pups, usually between 4 and 6 in number, are then born live into the open sea.
There are other members of genus Alopius besides vulpinas, and all of the species are listed as vulnerable. Fishing net entanglement and a slow livespan have led to decreasing numbers in recent years.
