Baby shark, doo, doo, doo, doo, doo, doo.

In what could be the first recorded case of asexual reproduction in the species, a baby shark was born to one of two moms in a smooth-hound shark tank, as captured in footage released by Newsflash.

The mysterious conception occurred at the Acquario Cala Gonone in Sardinia, Italy, where the two female smooth-hound sharks have resided for the past decade — without a single male shark present.

Local media outlets reported that experts believe the pup, dubbed “Ispera” by staff at the aquarium, is in fact a clone of its mom — via parthenogenesis, in which an embryo is fertilized by a polar cell, a byproduct of meiosis, when germ cells divide to create either an egg or a sperm.

The polar cell in females, which contains a duplicate of an egg’s DNA, is superfluous in the presence of a male’s sperm. But during parthenogenesis, which has been observed in some sharks and other animals, scientists believe that the polar cell may be employed as supplemental DNA to the lonely ovum.

This form of asexual reproduction occurs rarely in females with little prospect of finding a mate due to low population density — or, in Ispera’s case, no potential father at all.

Marine biologists at Cala Gonone have sent DNA samples to a laboratory to confirm their hypothesis.

Parthenogenesis is relatively common in invertebrates, such as worms, insects, some arachnids and crustaceans, and is more rarely observed in vertebrates, including some amphibians, lizards and fish.

Indeed, self-cloning births were confirmed in three shark species: the bonnethead, the blacktip shark and the zebra shark. Ispera’s birth may well prompt a fourth species, the smooth-hound, to be added to the list.
