Urogymnus

Urogymnus is a genus of stingrays in the family Dasyatidae from marine, brackish and freshwater habitats in the Indo-Pacific and tropical East Atlantic regions. The genus was previously considered to be monotypic, containing only the porcupine ray (U. asperrimus). Molecular phylogenetic research published in 2016 reassigned several species from Himantura to Urogymnus.[1]

gollark: Yes, I am aware of what a "skid" is.
gollark: have been correct.
gollark: Although I think 2 *and*3 might hv
gollark: If you want to know, they were:- me specifically- basically all of esolangs- every person who is not 1337 enough to be writing all their stuff as baremetal C/assembly
gollark: Hmm. That was my second guess.
