The deep sea of Eryobis is a large and scarcely studied habitat, yet it is also likely one of the most biodiverse. ROV expdeditions and deep sea fishing by both researchers and natives continuously bring up extraordinary and strange animals.
When one goes deep sea fishing in the Vyaris Ocean, a fish that is often caught at mesopelagic depths is the black gladdo (Eryobalepus atratus). This up to 40cm long deep sea bunnyfish seems to be quite common in these deep tropical waters. Stomach contents of these fish have revealed that they are not picky eaters and will feed on whatever they think they can fit in their mouths, which seem to be able to open up very widely and can expand to twice the width of the head.
The phylogenetic placement of gladdos is a bit unclear, as they possess a mixture of primitive and derived traits and have therefore been placed in their own branch on the family tree.
