Portunus segnis (Forsskål, 1775)
Males have a dark olive green blue carapace marked with numerous pale white spots on especially towards the rear and along the sides. The females are similar to the males except that the tips of their legs are red with a brownish red tinge rather than being blue tinged with intense rusty red.

Lives mainly in coastal waters in seagrass meadows, along mangroves and intertidal mudflats. Found under rocks and in rock pools, on sandy or muddy substrate. Opportunistic predator, primarily a carnivore preying on a variety of benthic animals and less marine plants and sea
The populations of P. segnis, an omnivorous predator much larger than any of the sea’s native portunid crabs, and lacking predators as adults, may outcompete local taxa.
There are negative impacts on fishery economy that relate to the predation by blue swimming crabs on fishing catches and the damage of fishing nets where they get entangled.
