**Odontognatha**

**Odontognatha** (lit. "toothed jaws") are a clade of Deinognatha, consisting of all semiaquatic and fully aquatic Deinognathans.

## Description

Odontognathans first emerged around 4215ma, evolving from Deinognathans who utilized riverbanks as hunting grounds. Over the next 35 million years, various lineages of Odontognathans have evolved a variety of lifestyles, although a number of traits have remained consistent among them.

Odontognathans live either semi-aquatic or (in the case of the Thalattotheria clade) fully aquatic lifestyles. Their eyes are located near their cephalothorax, while their spiracles are located on their upper abdomen.
