Duocerus longus
Descended from D. pluma, this muscal consumes F. foliumicroeus, F. cenafolius and the young of F. foliumegaeus. The main alteration from the ancestor is longer fronds, up to 9 inches long, which gives a greater area for it to catch its prey. To allow for this change, musculature in the fronds has increased proportionally, which is made sustainable by the increase in food capture on average. Due to the longer fronds, they have a slightly longer regeneration time, although this is mostly counteracted by increased food. Apart from this change, D. longus is largely unchanged from its ancestors.
