Every year thousands of Australian Giant Spider Crabs march into the shallows of Port Phillip Bay to moult and seek safety in numbers. It is the largest-known crab migration on the planet.

In recent times, this impressive congregation has facing serious challenges. Crabs are being taken out of the water in higher numbers. 

This causes habitat destruction, pollution and littering of the seafloor, and increased safety risks to the general public.

Our knowledge of spider crabs’ life cycle—including migration patterns and population dynamics—is incomplete. Without this crucial knowledge, the sustainability of their population and fate is uncertain.

Your elected representatives have the power to protect our spider crabs.

Send a letter to key Victorian ministers asking them to set a no-take period to prevent marine damage until science can tell us more about the spider crabs.
