Found from southern Russia to China, The Fins United Initiative is excited to introduce you to the banded houndshark (Triakis scyllium)! Relatively widespread and common in this range, they’re found on the continental and insular shelves as well as estuaries or shallow bays. The banded houndsharks like sandy substrates and also like seaweed or eel-grass flats. Reproductivity is largely a mystery but it is known that they are an aplacental viviparous species and give birth to 10-24 pups per litter.
Virtually no information is currently available on this next freshwater stingray TFUI is introducing you to, the Thorny river stingray (Potamotrygon constellata). Observed in the Amazon and Solimões River basin in South America, unfortunately scientists haven’t been able to do more research on these animals. This freshwater stingray reaches a maximum disc width of 62 cm and is a muddy brown-to-gray color. No reliable photos of this animal was found.
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.
