Tasmanian Giant Crab
Weighing in up to 17.6 kg (30 lb) with a carapace width of up to 46 cm (18 in), the Tasmanian Giant Crab is considered the largest and heaviest species of crab in the world. Found along Australia’s southern coastline, from New South Wales to Western Australia, the crab is very long-lived and slow-growing, making it vulnerable to overfishing.
