Pneumapiscus limbus
These zone 3 omnivores evolved from H. omnimendus, measuring between 14 and 18 cm. They feed on all muscals in zone 3 barring flotensis, and T. extensiensis and T. trifecta, using the same rip-and-tear biting method as H. predata to prey on larger muscals, with increased jaw muscle to aid that. Their middle fins have elongated, and increased muscle mass allows them to range much further and get more food. To make maneuvering more efficient, the front and back fins have increased articulation and become shorter, meaning less mass has to be moved for the same amount of change in direction or speed. Their tails have also lengthened, with two small fins on the side for improved manipulation. They, like hexapiscus before them, lay somewhat large clutches of small eggs, and guard them until they reach maturity and hatch.
