Common Fraboo

The common fraboo replaced its ancestor the metamorph fraboo. It has spread across Darwin inhabiting many of rivers and riparian zones. Like its ancestor it has an advanced life cycle which grows from eggs to larva to pupa to adult. The adults now produce hundreds of eggs into nutritive sacks in the river. The eggs hatch into larva which live underwater and filter-feed on microbes. Once they eat enough they will turn into an immobile pupa that transforms its aquatic worm-like body into a common fraboo body. Once they leave their slimy "chrysalis" they will come onto land and feed on decomposing material in the riparian zone and boreal.

With few predators they live a simple life eating and mating. However like their ancestor they can raise up their "horns" scare away predators. If they sit down their 10 legs can hide under their shell. Their grip is hard to pry off. In addition their horns can retract into their neck and seal up. Thus creating a nearly impenetrable fortress against small predators. Their shell is extremely hard and strong due to its dome shape.
