A giraffe’s tongue is long so long-neck uses its tongues to clean its ears. The color of the tongue is black. This is one of the weird facts about the giraffe.
Giraffe’s and humans have the same number of bones in their neck. Giraffe’s age can be calculated from its spots. The darker the spots, the older the giraffe.
Snakes smell with their tongue. They have ears inside their heads. Some snakes can survive without the meal for up to two years. Snakes kill 10,000 people every year. Snakes don’t have eyelids.
Rats like to be tickled. High-pitched chirping is how they laugh, and some rats prefer being tickled to eating.
Dolphins are another species that are often focussed on for their smarts. A recent finding that exemplifies this is that dolphins actually have names for one another (which form when other dolphins mimic the sounds they make) – and recognize their own title when it is called by other dolphins.
