The single mother from the marine aquarium in Detroit has spawned 3 offspring and is waiting for the next spawn; This is a rare phenomenon, but possible; The hypotheses: "virgin reproduction" or a bisexual shark; Holy Mary in the Jaws version
Voila system!
Storm at the Bell Island Marine Aquarium in Detroit: A female shark, kept for the past six years without a male, spawned three sharks. CNN reported that the spawning, which is causing waves among the workers there, is called "virgin birth". "There isn't and hasn't been any trace of them around, in all the years we've kept the sharks," said the aquarium's curator, Doug Sweet.
Sweet said that two of the offspring were born in July, and their brother joined the single-parent family early last week. According to him, the fourth offspring is expected to emerge in a few weeks. He added that the health condition of the mother and the sharks, whose length reaches about 60 cm, is satisfactory. These are bamboo sharks, whose natural habitat is the South Pacific Ocean.
"When it comes to sharks, amphibians and reptiles, these kinds of phenomena sometimes happen. It's rare, but it happens," Sweet said. He put forward two central hypotheses regarding spawning without assistance from the male sex. The first is that it is a process called "virgin reproduction", which allows unfertilized eggs to develop into embryos without sperm. The second possibility is that the happy mother is blessed with a bisexual fertilization system, that is, testicular tissue at the same time as the ovaries.
