1. Immortal Jellyfish
The Turritopsis dohrnii, also known as the immortal jellyfish is the poster child of incredible animals. Fully grown, it is the size of a human pinky nail. It was discovered in the 1800’s however its incredible abilities went undiscovered until the 1990’s. The immortal jellyfish has the ability to reverse its life cycle and return to the first stage of life. When under stress such as starvation, physical damage or other environmental factors the immortal jellyfish avoids dying by completely transforming all of its cells into a younger state. It can even transform into sperm and egg cells and asexually reproduce hundreds of jellyfish genetically identical to the original adult.
2. Belgian Blue
The Belgian blue is notorious for its incredibly muscular frame and massive size. This is actually due to a genetic mutation that stops the production of Myostatin. Myostatin is the gene responsible for stopping muscle growth after a certain point. This mutation results in double muscling. The Belgian blue is one of the most incredible animals. Although it yields a greater amount of lean meat and has a relatively short gestation period its thin skin and lack of fat makes it sensitive to the cold. The purebred calves are also quite large thus a natural birth is not feasible.
3. Finger Monkey
The Pygmy Marmoset also known as the finger monkey is the smallest species of monkeys to exist in the world. They are active as any other monkey and also possess the incredible ability to rotate their heads 180 degrees. They can jump as high as 15 feet into the air and have a life-span of 12 to 18 years. They can be kept as pets although certain precautions need to be taken as they become aggressive upon reaching adulthood an require a certain habitat and companionship.
4. Japanese Spider Crab
The Japanese spider crab is the world’s largest arthropod and can live up to a hundred years. Its body stops growing at about 15 inches. However, its legs can grow up to an incredible 12 feet and weigh up to 44 pounds. They can survive losing up to three legs, which will sometimes even grow back.
5. Blue Dragon
The Glaucus atlantics also known as the blue dragon is a sea slug with impressive defense tactics. It rarely gets bigger than 3cm. An air bubble stored in its stomach keeps it afloat while its blue color helps it camouflage against the water. By itself the blue dragon is not venomous, however it feeds on small jellyfish and stores their stinging cells. When it feels threatened it releases these stinging cells and delivers a potent sting.
