Fish Fact of the Day. 🧪
The Greenland Shark has the longest lifespan of all vertebrates (estimated to be 250 to 500 years), and as an adaptation to living at depth, it has a high concentration of trimethylamine N-oxide, which makes the meat toxic.

i will never be pregnant for a decade with ten, or maybe a few hundred, pups 😭😭😭😭😭😭😭😭

Reproduction
Greenland sharks are born alive (a process known as ovoviviparity) after an estimated gestation period of 8–18 years.[5] This extremely long gestation rate is crucial to understanding effective conservation strategies around the Greenland shark. Given the ongoing fishing pressures on Greenland sharks, their prolonged long gestation period and slow reproductive rate may severely limit their ability to recover from overfishing.
Estimates of litter size have varied across studies. Some suggest that this species produces up to 10 pups per litter, each initially measuring some 38–42 cm (15–17 in) in length.[51] Based on these estimates, Greenland sharks may have between 200 and 700 pups during their lifetimes.[5] Within a Greenland shark's uterus, villi serve a key function in supplying oxygen to embryos. Oxygen supply is proposed to be a major limiting factor in the size of litters.[57]
Other studies, however, which take into account ovarian data and analysis of other squaliform shark species, have estimated that Greenland sharks may produce from 200 to 324 pups per litter, each pup measuring from 35–45 cm (14–18 in) in length. The same study also confirms that Greenland shark embryos develop inside the uterus without a placenta.[16]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:73hkwya2rrrfg26vdcwnmo6p/bafkreidxvcirjzljh23ozgdouo3kwb3yplgaxeu4vwuzecmtbhrxe5kowu)

Still get over how long the Greenland Shark lives, fucking bastard.
It's wasted on them, ...needed for us, ...to break that 70 year cycle of human foolishness, and for other things....
