Greeneye Spurdog (Squalus chloroculus) goes by a variety of name. What is it with spurdogs having SO MANY NAMES? Alright, alright, we’ll list them: Blainvilles Dogfish, Blainville's Dogfish, Green-eye Dogfish, Grey Spiny Dogfish, Northern Dogfish, Northern Spiny Dogfish, Shortspine Spurdog, Shortspine Spurdog, Spikey Dogfish, aaaaaaaaand last but not least Spiny Dogfish. There may be other names we’re missing but to be honest are you going to remember all of these? Probs not. And that’s okay! Just remember the super duper important one: the scientific name.
The greeneye spurdog is a medium sized dogfish that we actually know very little about. For example, we know males of this species mature at about 68 cm total length (TL). The females? *shrugs*
They look similar to another dogfish, Squalus montalbani, and both species were previously incorrectly identified as Squalus mitsukurii. Like other dogfish, they are grey on the top and have a pale tummy. The greeneye spurdog has big eyes, a short snout, and tiny gill slits. Their fins are a lighter colour than their body and both dorsal fins have dorsal spines in front.
This is a viviparous (aplacental) species that is endemic to southern Australia from New South Wales to Western Australia. The IUCN has assessed them as Near Threatened (NT).
