A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.”
[3] [4] This is seen in sperm whales as well. To allow the mother to dive and gather food and resources, the whales in their social group separate their dives allowing for the baby to be monitored and overseen by a whale during all times. [6] Superb starlings also perform this behavior. Their group living situation contributes to many potential ...
In modern-day Japan, two cuts of whale meat are usually created: the belly meat and the tail meat. In the early 19th century, 70 different cuts were known. [22] People still call the belly and tail cuts by their special whale meat names; also, different parts of the body such as the tongue retain their jargon names (see below).

One way parthenogenesis can occur is when a female’s egg fuses with another cell, often a cell leftover from a process that allows the female to create the egg. That cell, known as a polar body, gives the egg the genetic information it would normally get from sperm. The cell starts dividing and that leads to the creation of an embryo.
In the end, the scientists were able to recognize bats’ bickering over food and making calls in other circumstances, such babies as being left alone without their mothers, according to the study.
The sperm whale or cachalot [a] (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.
Left to right: A sample of solid raw spermaceti, a spermaceti wax candle and a bottle of sperm oil. Spermaceti / s p ər m ə ˈ s iː t i ˌ-ˈ s ɛ-/ is a waxy substance found in the head cavities of the sperm whale (and, in smaller quantities, in the oils of other whales). Spermaceti is created in the spermaceti organ inside the whale's head
