Description: Snakes' vision is not particularly conspicuous (generally being better in the arboreal species and worse in the terrestrial species), which does not prevent movement detection. In addition to their eyes, some snakes (crotalineans - or dimple snakes - and pythons) have sensitive infrared receptors in deep grooves called pits that allow them to feel the heat emitted by their bodies. This is extremely useful in low light places. As snakes do not have external ears, hearing can only detect vibrations, but this sense is extremely well developed. Most snakes use their forked tongue to pick up scent particles in the air and send them to the so-called Jacobson's organ, located in their mouth, to examine them. The fork in the tongue gives the snake
Description: An elephant's skeleton constitutes about 13% of its body mass. Larger animals exchange energy with the environment more slowly than smaller species, due to the difference in the surface-to-volume ratio of the individual. Thus, elephants can easily overheat when in activity, as they cannot quickly lose heat to the environment. In view of this, they divert large volumes of blood to the ears and fan them, thus releasing heat to the environment and promoting its cooling.
