- Oval Spider Crab
Carapace flat, variably coloured, usually in symmetrical patterns of red-black, red-white or brown-white. Three short spikes (prongs) between the eyes. Legs very thin. Up to 1.5 cm wide (carapace).
Three-pronged Spider Crabs are cryptic, hiding between fronds of seaweed and seagrass. Despite being difficult to see, they are one of the most common crabs in many sheltered environments in the Melbourne region. They are presumed to be scavengers but might be micropredators. They feature in the diet of several species of bottom feeding fishes.
Muddy seagrass or algae areas on shallow reefs, to depth of 85 m.
Not harmful but a nip from claws could be painful.
