6. When there is a dispute over who should take over from a deceased alpha female dwarf mongoose a groom-off will ensue. The two combatants could groom each other for up to four days. The winner will be the one that proves themselves more persistent. Both will end drenched in saliva.
7. To protect the giraffe’s brain from sudden changes in blood pressure when it lowers its head to drink, it has valves to stop the backflow of blood and elastic-walled vessels that dilate and constrict to manage flow. NASA has done research on the blood vessels in giraffe legs to get inspiration for human space suits.
9. Wild dogs have developed large stomachs to transport food back to the den. They then regurgitate it for the pups and stay-at-home dogs. They can do this for great distances so long as they don’t rest. At that point the digestive process will begin.
10. The word chameleon is derived from the Greek, khamai, meaning “on the ground” or “dwarf” and leon meaning “lion.” Chameleon therefore translates as “dwarf lion.” This is said to be due to its ferocious behaviour.
11. Elephants do not have sweat glands but they do cool down when water evaporates off their body. In times of extreme conditions, they sometimes put their trunk down their throat and suck water up which they then squirt over their body.
