Why do baby sharks swim with their mothers?
They presumably switch between uteri for that reason. While still developing, they are searching for eggs, which is a vital talent, especially when there are other embryos around. Toby Daly-Engel, a shark expert at the Florida Institute of Technology, claims that the embryos don’t appear to be fighting with one another; rather, they are consuming one another.
Does a baby shark need its mother?
The most cutting-edge kind of reproduction is viviparity. As the newborn shark grows inside its mother’s body, an umbilical cord supplies it with nourishment and oxygen. Mammals operate in the same way as this. But unlike mammals, the pups must fend for themselves right away after birth since they are completely autonomous.

Do sharks sleep?
According to recent research published in Biology Letters, sharks can sleep, and frequently choose to do it with their eyes open. In order to keep oxygen-rich water flowing over their gills, certain sharks must move continuously, which has led to the long-held belief that they do not sleep at all.
Do female sharks have two uteruses?
