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: I ended up using all the coal the tunnel borer mined on feeding the tunnel borer, it still wasn't enough.
gollark: Consider a silk touch pickaxe.
gollark: I don't much either, but we have a tunnel boring machine for primitive automining on here.
gollark: I should probably get something like this, it would be great to be able to just throw away stuff I'm not using.
gollark: Why use golems to pick up your waste when OC drones also could at twice the expense and hassle but also coolness?
