Flisilensis lahicuatillum
Flisilensis lahicuatillum is descended from Flisilensis marineris to live underwater. A number of new adaptations have appeared in this species. The first pair of legs have changes to manipulate substrate and food by facing forward and having the final segment of the legs become a three point inflexible claw. As a result of this the second pair of legs has reverted to a form for walking away from the wing shaped legs of their ancestor to provide six walking legs. The second body segment has flat outgrowths to help with directional movements when L. Lahicuatillum needs to swim using its tail which has become more oarlike. The dorsal plate of the third segment not extends over the fourth segment to protect the body somewhat from predators.
All individuals will make small domes with rocks and shells using their new claw-like forelimbs. They will use these domes as shelter when not searching for food or mates. The domes will be made in depths of 40 to 210 feet deep. F. lahicuatillum feeds on any low growing non-toxic polyphs they can find using their piercing and sucking mouthparts. They grow many small hairs on their underside that trap air that they will breathe. When the air bubble trapped by the hairs is low they will swim to the water’s surface to refill it.
When breeding they find a mate then the pair will make another dome of debris in areas with heavy vegetation where the eggs will be laid and fertilized. After fertilization the parents will return to their home ranges. Each nursery dome will contain around five eggs and will be where the hatchlings will stay until they are large enough to leave and build their own dome. They will be around 2cm upon hatching and will leave the nursery dome when they reach around 7cm. The adults typically reach 15-16cm. Adults typically only mate once every 2 years and will only be reproductive until they reach around 6 to 7 years old after which they may live for another year or two.
