Document Summary

Ingest prey whole: modified jaws open their mouth bigger to ingest the whole thing. Eating chunks is derived: adaptations evolved, teeth, claws, etc. The mammalian mouth has 4 types of teeth: Incisors front teeth: canines sharp, premolars short, molars have a flat surface, modifications based on diet. Herbivores eat plants/leaves: grinding and pulverizing molars break fiber cellulous, cutting incisors cut the plant, canines and premolars are not very useful. Carnivores meat eaters: capture and killing canines catching and killing prey, shearing premolars tearing meat off bone, molars aren"t very useful. Extracellular digestion is outside the cell: chamber cavity of space. Gastrovascular cavity blind ended set: food enters the mouth and cycles around the cavity; digestion occurs, absorption occurs when useful nutrients go into the body. Incomplete gut missing a part (anus); 2 way gut: elimination comes out the same opening (mouth)
