The warmer a rattlesnake, the faster it vibrates its tail. [6] Rattlesnakes tail-vibrate faster than other snakes, with some individuals nearing or exceeding 90 rattles per second. [7] [8] This makes rattlesnake tail vibration one of the fastest sustained vertebrate movements—faster than the wingbeat of a hummingbird. The movement is possible ...
The snake detection theory, [1] [2] [3] also sometimes called the snake detection hypothesis, suggests that snakes have contributed to the evolution of primates' visual system. According to the theory, predatory pressure from snakes has selected individuals who are better able to recognize them, improving their survival chances and therefore ...
Pursuit predation becomes a better strategy than ambush predation when the predator is faster than the prey. [2] Ambush predators use many intermediate strategies. For example, when a pursuit predator is faster than its prey over a short distance, but not in a long chase, then either stalking or ambush becomes necessary as part of the strategy. [2]
Snakes are cold-blooded, meaning they cannot regulate their own body temperatures like humans or other warm-blooded animals. A snake’s body temperature changes with the outside temperatures.
The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.

If the snake manages to bite the eagle, she could die due to its venom. The mother eagle makes it back with the snake and feeds her babies. Unfortunate for the snake but delicious lunch for the ...
Contrary to the popular belief that snakes can dislocate their jaws, they have an extremely flexible lower jaw, the two halves of which are not rigidly attached, and numerous other joints in the skull, which allow the snake to open its mouth wide enough to swallow prey whole, even if it is larger in diameter than the snake itself.
