7 Weirdest And Rarest Animals On Earth

The animal kingdom is so vast and diverse that we don’t think humans would ever be able to discover them all. As per the statistics, Earth is home to 8.7 million species and about 5 million of them are yet to be discovered! Even from the millions that have been found and known, we only see less than 1% during our lifetimes. That’s why we decided to put together some of those rarest and strangest creatures for you to see and be amazed at. Scroll down to see who else is sharing the same planet with us!

The axolotl is not a fish although it’s informally known as the “Mexican walking fish”.This amphibian is a type of Salamander and is native only to Lake Xochimilco and Lake Chalco in the valley of Mexico. An Axolotl can grow up to 12 inches and weighs about 8 ounces. Unlike other amphibians, these creatures never lose their gills they had in their younger stages of the life cycle and stays in the water forever. Axolotls have this amazing ability to regrow the organs and limbs once they lose them. It could be crushed lungs, heart, brain, amputated limbs, or broken spinal cord, an axolotl can regenerate everything within a few weeks with no trace of any scars.

The cassowary is a large flightless bird of about 2m height and 60kg of weight and is native to southeast Asia and Australia. The cassowary is a beautiful creature with a blue face, two red flaps of skin hanging down from the neck, and a black bunch of feathers on its back. But don’t let the looks fool you. It’s also known as the world’s most dangerous bird since they can inflict serious or even fatal harm to humans and dogs with their muscular legs and they use their sharp dagger-like claws which are up to 5 inches long, to slice and puncture the enemy.

A cassowary can move fast on both land and water. They usually can run at a speed of 31 miles per hour and jump up to 7 feet into the air.  Female cassowaries lay 3-8 eggs at a time and males sit on them for about 50 days until they hatch. It’s the male birds that take care of the chicks who stay in the nest for 9 months. Females don’t take care of the eggs or chicks but lay eggs on the nests of several males within her territory. Currently, cassowaries are listed as endangered species. 

03. Vampire bat.

Being a carnivorous mammal, vampire bats feed entirely on blood. They grow up to 3.5 inches in length and weigh about 2 ounces, but it can double in one feeding. Like all the other bat species, vampire bats also sleep during the day and go hunting at night. They drink their prey’s blood for about 30 minutes. These prey can be horses, cattle, and sometimes humans. They don’t drink a lot as to harm the host but their bite can cause various infections. Vampire bats have few teeth because of their liquid diet but they are extremely sharp. Young bats feed on mother’s milk for about 3 months. These nocturnal mammals are usually found in the tropical regions of Mexico and Central America.

04. Glaucus atlanticus.

This beautiful animal, widely known as a blue dragon or blue angel, is a species of sea slugs. They usually don’t swim but float using the surface tension of the water or get carried along by winds or water currents. This sea slug eats venomous jellyfish using its sharp teeth and strong jaws. Later it can concentrate the venom of the jellyfish it ate and release a sting even more powerful and venomous than that of the jellyfish. These sea slugs are rarely seen on Australian shores and sometimes in the warm waters of Indian and Pacific oceans.

05. Japanese spider crab.

Spider crab has the largest arthropod leg span which measures up to 1 – 1.2 meters. They weigh about 42 pounds. They live in the Pacific ocean near Japan in a depth of 164- 1640 ft. These crabs don’t hunt. Instead, they feed on dead plants and animals. Female crabs lay more than a million eggs but not all of them survive. Those who hatch don’t get parental care and molt for the 1st time after 9-12 days after they hatch.

06. Glass frog.

These amphibians are mostly lime green and the skin on their abdominal area is transparent; hence they get their name “glass frog”. Their internal organs such as the heart, liver, and intestines are visible through the skin. They live on trees and come out only in the mating season. Glass frogs are usually about 3-7.5 in length and are seen in the forests of Central and South America.

07. Fainting goats.

What you might find on the internet about this American breed of goat is hilarious because they have a very rare hereditary condition where the muscles go all stiff when they are threatened and fall over all of a sudden. Although they never actually lose consciousness, they are commonly called fainting goats after this genetic condition called myotonia congenita. This isn’t harmful to the goats since they only affect their muscles, not the nervous or cardiovascular systems, and they recover after 10 -20 seconds.
