They do have enlarged teeth in the back of their mouth [14] but their gums are significantly larger and the secretions of their Duvernoy's gland are only mildly toxic. [13] [15] Evidence suggests that garter snake and newt populations share an evolutionary link in their tetrodotoxin resistance levels, implying co-evolution between predator and ...
The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes, such as the reticulated python, Burmese python, or the occasionally sympatric green anaconda, and can reach lengths from 3 to 13 ft (0.91 to 3.96 m) depending on the locality and the availability of suitable prey.

Aglyphous snakes (lacking grooves) have no specialized teeth; each tooth is similar in shape and often size. When teeth vary in size, as in some bird eaters, they do not vary in shape. Most aglyphous snakes are non-venomous; some, like Thamnophis, are considered mildly venomous. The feature is not a synapomorphy.

Some species, including woodpeckers, have two egg teeth; one on both the upper and lower bill. [4] After time the egg tooth falls off or is absorbed into the growing chick's bill. [5] Some precocial species such as the kiwi, and superprecocial species including megapodes, do not require an egg tooth to assist them in hatching. They are strong ...
