About Guinusia chabrus (Linnaeus, 1758)
Guinusia chabrus is a sturdy, square-bodied crab. It has a smooth, dark red-brown carapace that may bear four white spots arranged in an approximately semicircular pattern. Its legs have yellow longitudinal ridges, and yellow knobs are present on its pincers. This crab is distributed along the coast of Southern Africa, ranging from Luderitz to Sodwana Bay. It lives in subtidal areas down to at least 100 meters deep. Guinusia chabrus is common on reefs, where it is often found in crevices or hiding under other benthic organisms. It is a scavenger, and along with Haliotis midae, it forms a major part of the preferred diet of Octopus vulgaris in False Bay, South Africa.
