What else. ;-) They just do what some other snakes do.
"Thanks for an informative article, the political republican side keeps splintering and evolving into this extreme conservative movement that devours itself."
Among animals
The short-tailed cricket is known to eat its own wings.[16] There is evidence of certain animals digesting their own nervous tissue when they transition to a new phase of life. The sea squirt (with a tadpole-like shape) contains a ganglion "brain" in its head, which it digests after attaching itself to a rock and becoming stationary, forming an anemone-like organism. This has been used as evidence that the purpose of brain and nervous tissue is primarily to produce movement. Self-cannibalism behavior has been documented in North American rat snakes .. https://en.wikipedia.org/wiki/Rat_snake : one captive snake attempted to consume itself twice, dying in the second attempt. Another wild rat snake was found having swallowed about two-thirds of its body.[17]
[Think about that. "About two thirds..." Some 70% of registered Republicans believe trump's stolen election 2020 lie. Gobble gobble.]
