Tonbodiver

As the climate changed and the waters they inhabited became colder and colder, the seaplane tonboswarmer began to struggle. Those that moved out of the colder and colder rivers and into the more temperate coasts did better. These populations would eventually give rise to a new species, known as the tonbodiver.

While the wings do not help the tonbodiver with flight, they are used in a more active manner than the seaplane tonboswarmer. The first pair of wings act almost like they would be in flight, except to beat through water rather than through air. The second pair of wings, which were once used to sit on top of the water surface(which they can still technically do, but rarely need too because of their different lifestyle), are now used to help the tonbodiver steer where they can be adjusted to help change direction. The tail also performs a similar function to the second pair of wings in that the fin helps steer, though it can also be used for quick bursts of speed in a pinch for when the tonbodiver needs to evade a predator.

While they will spend most of their time in water, tonbodivers can move on land, though they are not exactly competent on substrate. This occurs on beaches, where a tonboswarmer is usually moving from one tidepool to another at low tide, or perhaps taking advantage of vegetation laying around on the beach. When they move on land, they prop themselves up with their second pair of wings while using the first pair to push them forward, not too different from how the terran mudskippers move.

While the tonbodiver adults eat a wider variety of soft vegetation, the larvae of this species more closely resemble typical swarmers and are filter feeders. As they grow, they develop their armor and the second pair of fins buds out. By the time they grow into their mature adult form, they have developed sex organs and thus begin their search for potential mates.

While the tonbodiver primarily inhabits warm coastal areas, they also live in the Bumpy Polar Coast and go onto the Drake Polar Beach. Because of the cooler temperatures, however, the tonbodivers do not fare as well as they do in temperate waters, and so are restricted to the southernmost parts of these two biomes.
