Pastinachus
Pastinachus is a genus of stingrays in the family Dasyatidae. This genus was long held to be monotypic, containing only the cowtail stingray (P. sephen). Recent studies of Indo-Pacific stingrays have revealed that there are in fact a number of different species of Pastinachus, and that some former junior synonyms may need to be resurrected.[1]

gollark: (Sidenote: interestingly, apparently the development of farming actually led to significantly *worse* life for people for quite a long time, because it allowed much more population per land area, causing people to end up at a subsistence level and quite malnourished and stuff)
gollark: Modern supply chains are complex, and while we could not have those you would then lose out on stuff like microelectronics, medical things, and the economies of scale meaning you can have nice things cheaply.
gollark: How is that better? We need widescale coordination to do anything.
gollark: It's *great* if you like dying of otherwise preventable diseases, after a life basically free of any modern amenities consisting of... hunter-gathering, or whatever people did.
gollark: * carcinize
