Two first shark fetus

A pair of sharks, both of which have two heads, are found in a personal collection. One of the above two children was in the vessel since it was discovered in 1934 off the coast of Argentina.

Both specimens are male fetuses separated from a mother gray shark. In addition to the two ends, each specimen has two identical dorsal fins. Two-headed phenomenon is most common in reptiles, amphibians and fish. These animals often die very early. A two-headed snake caused a stir in the scientific world in 2006, after being carefully trained, the two heads knew how to eat in order. The reason the fetus develops in this direction is still unknown: parasites, poor nutrition, gene disorders and pollution can all be the cause.
