Sandhopper

Splitting from their ancestor, the sandhopper lives along the bottom of Colddigger Polar Bay. Crawling along the sand with its modified fins, it feed on the roots of the marine bubbleweed as well as young marine crystal growths. It will also go after marine krillpedes should it come across them, especially when they are younger and more agile. When they reach maturity, they move slowly and are able to breath without choking with their modified frontal gill which has split into two openings and moved along its sides.

At night they find a safe, secure place to hide amongst the rocks and marine crystal and produce a thick mucous coating that hides their scent. This allows them to sleep through the night in relative peace without having to worry about predators. Young ones, however, will hide amongst the marine bubbleweed roots, their coloration helping them to blend in with their surroundings.

In order to take in enough oxygen in its more sedentary life cycle, its front gills have now become pump-like, extending and contracting in a steady pattern which pumps in water which is then passed though its respiratory system before flowing out out of its side gills.
