Pom Pom Crabs

You can’t explain craziness. Some of us are just born with this unique characteristic that defined our cool quotient. The animal kingdom is also not untouched by the craziness factor. We all have heard about animals having funny appearances, behaving in crazy ways, having ridiculous eating or sleeping habits, or employing funny means to hunt or trap animals for prey. Below is a list of craziest animals that can make your jaws drop with their craziness! Have a look.

Craziest Animals

1. Hairy Frog

The hairy frog is an African frog species. It is uniquely known as the Wolverine frog or the Horror Frog because of its hairy wolf-like appearance. There are hair-like structures on the body and thighs of the male frogs. They are dermal papillae which contain numerous blood vessels that work like external gills. This frog has one of the craziest defence mechanisms where it can break its toe bones to produce cat-like claws when it is threatened. This occurs only in the hind feet. When the frog is at rest, the bones stay surrounded by a mass of connective tissue.  It is one of the craziest animals in the world.

2. Mustached Hipster Toad

This is a unique toad species native to China. These toads are also known as the Emei toads and the male toads have large snouts up to 9 cm in length. In the breeding season, male Emei moustache toads grow stiff upper lip spikes that look like a needle-like mustache.  The toads use these spikes to battle with rival toads for mate selection. A typical Emei toad can plunge his mustache into his rival’s stomach, stabbing with the sharp spikes.

3. Pom Pom Crabs

One of the craziest animals in the world, The Lybia crab is a species of tiny crab in the family Xanthidae, which is native to the Hawaiian Islands. These crabs are known for always carrying a small living sea anemone around in each of its claws which look like tiny boxing gloves or pom-poms. It is for this reason that these crabs are also known as the “Cheerleaders of the sea”.  These anemones help them to catch food from the rocks and protect themselves from predators. This crab threatens its enemies by waving its anemones around, whose tentacles have stinging cells called Cnidocytes.

4. Horned Lizard

Horned lizards are the toad-like North American lizards that are also known as “Horntoads”. They have a flat, round body with a blunt snout like a toad. A distinct feature of the Horned lizard is that when it feels threatened by a predator, it shoots blood from its eyes! What really happens is that when the Horned lizard feels threatened, it closes off blood supply to certain vessels due to which pressure in its head suddenly increases. Its sinuses and eye sockets get flooded with blood which is squirted out in the form of a   jet from each eye. It can reach as far as 1.5 m which scares the predator.

Woodpeckers are commonly found in major parts of the world except in the Polar Regions and Australia, New Guinea, New Zealand, Madagascar. Most woodpeckers spend their entire lives in trees. Woodpeckers have strong bills which they use to drill trees and chip barks. You can hear woodpeckers calling loudly or drumming on wood in the spring to attract females. The USP of a woodpecker is its really long and sticky tongue which it uses to extract insects and larvae from the tree trunks. Its tongue can be up to four inches long. It has a glue-like substance covered on its tongue which helps in extracting insects. It is one of the craziest animals in the world.

These birds feed off other birds and can fight with other sea-birds like terns or gulls to force them to drop fish they have caught. The Skuas can also scavenge waste discarded from boats.
