Killer whales are the most successful hunting animals on earth due to their intelligence and communication in pods, more than 80% of their hunting escapades are successful, they sometimes might just eat the nicest parts of their prey and leave the rest of the carcass to drift in the ocean.
Polar bears are the only carnivore that will deliberately hunt and kill a human as food. They are the only meat eaters that see use naturally as potential meals. You most likely won't escape death in an encounter with a Polar bear.
Elephants are the only land mammals that can't jump. They're not just shaped to do so for any reason.
If a Mantis shrimp was the size of a human it'd have enough speed and power to punch through a concrete wall at one strike. Their punches are so fast it generates heat which can be compared to the temperature of the Sun.
Sperm whales have distinct dialects for each pod. It is even said that the Sperm whales in the Caribbean have a different accent from others in the world. They are also the loudest animals in the world, their clicks are so loud their heads are shaped in that way just for the to safely receive and interpret the vibrations coming back to them. Never go near one, their clicks are capable of vibrating you most likely to paralysis or even death.
It takes about 30 years from Crocodiles to reach their maximum size.
Basenji is a dog breed that doesn't have the ability to bark, a very silent Dog indeed.
The horns on Rhinoceros heads are purely made from the same material that makes our hair which is Keratin. It's just extremely hardened hair. At least the poachers will leave them alone after learning this.
The human calls glow in the dark, we don't just notice because our brains are just too lazy to allow us know.
