Namazu

The Namazu is a extinct species recently discovered on the planet PNF-404.

Description
Its large size mirrors that of the modern Puffy Blowhog and other aerial Blowhog s. Unlike modern-day species, its fins are located further towards the front of the body rather than the center, and the end of the body has primitive sails along it.

Studies of the fossils of this creature had left scientists split on it either being an aerial Blowhog or an aquatic one. Those who support the aquatic theory point towards its primitive fins, and the placement of the frontal fins would make it impossible to steady itself in the air. Those that support the aerial theory counter it due to its close relations and appearance to aerial species.
