Biology
European Shore Crabs were first recorded in Port Phillip in 1900, introduced there accidentally as a hitch-hiker on ships from the UK or Europe. They have since spread throughout coastal Victoria, eastern South Australia and northern Tasmania. The crab is very aggressive, with strong pincers (chelipeds). It competes with and feeds on native species and may be a threat to these species. To prevent the spread of this invasive crab, recreational anglers must not use European Green Shore Crabs as live bait or return live unused crabs to the water.
Distribution
Worldwide. Isolated populations along southern Australian coast. In Victoria, European green shore crabs have been found in Gippsland, Port Phillip and west to Apollo Bay.
Habitat
Most areas, including rocky reef, seagrass and sand flats, to a depth of 60 m.
