Clarke Cleaner Echofin

The Clarke Cleaner Ecofin replaced its ancestor. It is the result of cleaner echofins migrating into Clarke Temperate Coast. There, they became tolerant to the colder waters and have gained adaptations that drove its ancestor to extinction. They spread to all of Dixon-Darwin's tropical and temperate coasts. It has evolved a layer of chitin over the gill on its tailfin. Like the Riparian Scorpodile, this layer has a series of slits in it so it can still breathe. These slits can also be closed and opened with a membrane. However, unlike the Riparian Scorpodile, which has a chamber beneath the slits, there is no space between the Clarke Cleaners Chitin layer and the gills. This is because it uses its gill slits to protect its delicate gills and improve its camouflage when it is hiding. When it detects a predator approaching, it will swim away as fast as possible and then lay flat against the seafloor, laying on its side, its gold, white, or brown body blends in with the sand. Because its ancestor's camouflage was incomplete, having bright blue gills and grey fins, it was replaced. It also possesses the ability to change its colors, however, this is limited to Gold, white, and brown, the colors of sand found in its range. However, it can't breathe when its hiding because its gill slits are closed. Thus, they can't hide forever. Other than this, it's exactly the same as its ancestor.
