Species: Therolamna dignathus
Ancestor: Therolamna isurodontus
Zone/s: 1
Size: 3m

Reproduction: They reproduce with internal fertilization, and pups develop for a month or two inside of the mother before being born into the pack. Females will give birth among the pack as they will all protect the young from a young age.

General Description: The dramatic increase in size from its ancestor is in continued response to their extremely large prey, T. gigantocetus. As a result oft his larger size, they are better able to succesfully hunt these filter-feeders.

They live very similarly to T. isurodontus, but have evolved a second jaw in their pharynx to better process their prey. The second jaw formed from the muscles that close the pharynx, which increased in strength. They live in packs of of 4-6, but can be found hunting alone. The smaller pack size is due to their larger body size.

They have evolved simple nostrils that are a small loop filled with chemoreceptors and a flap covering the exit hole from the chemoreceptors around their nose for better directional smelling. Their first gill has become larger due to the gill arch becoming a second jaw and now is used to pump water into the mouth to push over the gills, allowing them to breathe while their mouth is full.

Diet: Their primary diet consists of the large muscals in Zone 1 like U. cetorhinus, T. katharagnathus, T. gigantocetus, ect., but they will not hesitate to feed on smaller organisms like R. rotundus, G. aggressor, N. necrovora, and M. indespectus.
