The tallest man in recorded history was Robert Wadlow (1918 – 1940) from Alton, Illinois, who reached the height of 8 ft 11.1 in (2.72 m). The heaviest man in recorded history was Jon Brower Minnoch (1941 – 1983) from Bainbridge Island, Washington, who, at his peak weight, weighed in at approximately 1,400 lb (635 kg). These numbers sound really incredible, but humans are not the only species that has produced some gargantuan specimens. In fact, some forms of gigantism have been recorded in many animal species as well. Enormously sized animals have been often reported to live on islands where so called “island gigantism” frequently occurs. If an animal evolves on an isolated island with few predators to restrict its growth, it can reach a really stunning size. However, disturbingly oversized animals have been recorded on the mainland, too. There can be many reasons for gigantism in animals including genetic diseases and hormone disorders. To show you how large some specimens of individual animal species can actually be, we compiled a list with 25 Larger Than Life Animals That We Can’t Believe are Real. From a 417 kg (919 lb) tortoise and a 37 m (121 ft) jellyfish to a 25 lb (11.3 kg) rat and a 20 kg (44 lb) lobster, you will be astounded to find out how gigantic creatures can actually be out there.
At 210.2 cm (82.75 in) at the withers, a Belgian gelding named Big Jake stood as the world’s tallest horse in September 2012. Weighing in at 1,180 kg (2600 lb), the horse was raised by Jerry Gilbert of Smokey Hollow Farm in Ostego, Michigan.
Great White Shark
Nicknamed Deep Blue, the gigantic great white shark caught on camera off the coast of Mexico´s Guadalupe Island in 2013 is considered the largest Great White shark ever caught on camera. Deep Blue is estimated to be over 6.1 m (20 ft) long and it might weigh about 2,268 kg (5,000 lb).
The largest living cat is Hercules, an adult male liger (lion x tigress hybrid) currently housed at Myrtle Beach Safari, a wildlife reserve in South Carolina. He measures a staggering 3.33 m (131 in) long, stands 1.25 m (49 in) at the shoulder, and weighs 418.2 kg (922 lb).
The largest American alligator ever recorded was caught by the Stokes family in Mill Creek, Alabama in August 2014. The mammoth beast measured 4.8 m (15 ft 9 in) long and weighed 459 kg (1,011.5 lb). The alligator was mounted and put on display in a local museum.
The world’s largest winged cockroach is the Megaloblatta Longipennis found in Peru, Ecuador and Panama. A preserved female in the collection of Akira Yokokura of Yamagata, Japan measures 97 mm (3.8 in) in length and 45 mm (1.75 in) across.
