Blunt Stodée

Back on Earth, the seeming similarity between sharks and the bony fish known as strugeons was purely superficial and the result of convergent evolution. 

Semantics aside, because Eryobis has a small dozen of different fish groups that are referred to as "sharks" by explorers, the Eryobian equivalent of sturgeons do belong to these "shark" like groups. In fact, it has recently been revealed that the highly derived coelacants often called coeaaien, belong to one of two differernt groups that split long ago before either evolved to look similar to sharks. These groups became the Odontocoeiida, the "toothed coeaaien", and the Lamidocoeiida, the "plated coeaaien". Curiously, the apparent sturgeon equivalents of Eryobis were also part of this split and now it seems that most of the armoured ones belong to the Odontocoeiida while the less armoured or armourless ones belong to the Lamidocoeiida.

Common names are always quite variable and can differ per region, yet many of the armourless sturgeon like Laminocoeiidans are reffered to as surgées by human explorers. It is likely that this word came directly from the word for sturgeon from one of the imperium's colonies, given the similarity of the words. But curiously, it was the last part of the name that somehow became a standard suffix for Eryobian sturgeon like fish, which led to common names such as the word used for certain kinds of armoured sturgeon like bunnyfish, "stodée".

Stodées, such as the blunt stodée (Humeracanthus breviceps), are rather easy to recognise by their high set pectoral fins which no longer sport any fin rays at all, rather having been turned into a single large defensive spine on each side. Additionally, they have a row of spine like scales running down their backs that culminate in a very large spine at the base of the first dorsal fin. Despite sharing these defensive spines with many Laminocoeiidans, the stodées seem to have evolved them independently, because unlike surgées and kin, stodées possess true teeth and are thus considered Odontocoeiidans.

The blunt stodée can be found in equatorial rivers and lakes in western Bloëca. These fish are on the smaller side as far as stodées are concerned, typically maxxing out around 1.5 to 1.8 meters long. 

Their diet mostly consists of small mollusks and worms, but they have been observed also including various water plants in it. According to reports of both explorers and native Eryobians, these fish taste like mud and require a lot of seasoning to be palpable. This bad taste is likely caused by their freshwater habitat and benthic diet.
