I might use the idea for something else but not Karakhai. I already wrote a lot on Karakhai mating loosely based on real shark mating which is rare and terrifying. Karakhai are not monogamous. Mating is relatively rare, occurring once every three years for a brief window. During this period, it’s not uncommon for Karakhai to have several partners. Karakhai females usually pick their mates and Karakhai females value strong males. A very accomplished male warrior could find himself with as many as a dozen mates in a single mating season. Karkhai courtship and mating is very violent and utterly terrifying to outsiders who witness it. There are lots of “love bites” on both partners. The period leading up to the mating season is very dangerous for the rest of Scaraquans. Karakhai tribes that normally avoid each other meet up more often since mating between tribes is encouraged to diversity the gene pool and avoid stagnation. Karakhai are also more aggressive towards outsiders in the months leading up to the mating season, especially males who want to be able to impress females with their martial exploits. Karakhai, like most sharks, give live birth. Karakhai females give birth to one (50%), two (40%) or three (10%) pups. Because Karakhai all mate at the roughly the same time, females give birth at roughly the same time. Pups are considered children of the entire tribe. Every Karakhai is considered a brother or sister of the Karakhai born during its tribe's birthing season. It is frowned on for a mother or father to show favoritism to their own offspring (and the nature of their mating makes establishing paternity difficult anyway). Adults will all work together to care and feed for the young though they certainly prescribe to notions of tough love. Some tribes encourage pups to fight each other savagely, others repress it. This often depends on the relatively scarcity or abundance of food.
