Let’s dive into this next diverse Chondrichthyan: a chimaera! The Bigeye chimaera, Hydrolagus macrophthalmus, is known from 590-1160 metres deep in their subtropical range. From in the eastern Pacific Ocean from Chile, they are a brown across their entire body with no other distinguishing markings outside of their fins having a blue tinge.

Another day, another freshwater stingray. The Big-tooth river stingray (Potamotrygon henlei). Also known as the Tocantins River ray, they are a species in the family Potamotrygonidae like all other freshwater stingrays. They are endemic to Brazil, specifically the lower Tocantins and Araguaia basin and you can find them where the mud is plentiful. And trust me, it is plentiful here.
Phew, this shark goes by a few names! It goes by the “Black-vee Whaler,” “Fowler's Whaler Shark,” the “Graceful Shark,” the “Graceful Whaler Shark,” the “Longnose Blacktail Shark” and the “Grey Reef Shark.” Thankfully their scientific name remains the same: Carcharhinus amblyrhynchos.
