Giant African snail
If you’re a snail in Africa, you either go big, or go home. Ok, that makes no sense whatsoever, but bare with me. The giant Ghana snail, scientific name Achatina achatina is a large, voracious mollusk, sometimes measuring over 30 cm in length. It’s very adaptable, it eats a lot of things, and creates lots of offsprings – which is why it’s considered to be one of the most invasive species in the world. They originate from West Africa, but they’ve found homes all around the world, including areas such as Barbados or Florida – and they are often considered pests.
Chinese Giant Salamander
However, they are also routinely confiscated on airports in the US, because they are sometimes kept as pets (something which is not very wise, as they can spread dangerous bacteria). Like almost all gastropodes, these snails are hermaphrodites.
The Fruit Bat
The Chinese Giant Salamander (Andrias davidianus) is the largest amphibian in the world, sometimes reaching 1.80 cm. However, unlike the above mentioned snails, the Chinese Giant Salamander isn’t really that adaptable; the species is critically endangered due to habitat loss, pollution, and overcollection, as it is considered a delicacy and used in traditional Chinese medicine
The megabat is a group which features the world’s largest bats; however, not all species are always large: the smallest species measures a mere 6 cm. However, the largest species, Fruit bats (or Flying foxes as they are sometimes called) have a wingspan up to 1.5 m (4 ft 11 in)
They’re so big and intriguing that some biologists believe they descended from primates rather than bats and that mammalian flight ability has evolved more than once – however, most scientists disagree with this theory.
Giant Freshwater Stingray
Not all Stingrays live in the ocean – in fact, the biggest ones don’t. The Giant Freshwater Stingray usually weighs 500–600 kg (1,100–1,300 lbs). However, just like with the salamander, their numbers are dwindling. This species is threatened by overfishing and habitat loss; the World Conservation Union has assessed the giant freshwater stingray as endangered in some areas, and critically endangered in other parts.
The Japanese Spider Crab
Crabs are quite awesome animals, but there’s probably something in the waters in Japan… I don’t know. Weighing up to 19 kg, the giant Japanese spider crab has long been a Japanese fishing staple, and can inflict serious injury with its powerful claws. They have the greatest legspan of any arthropod, reaching 3.8 metres from claw to claw. Despite of its threatening appearance, the Japanese Spider Crab usually has a very gentle disposition .
