[2] This sea snail is found widely spread in the Indo-West Pacific, and occurs from east to South Africa, including Mozambique, Tanzania, Madagascar, the Red Sea, the Gulf of Oman, Aldabra, Chagos and Mauritius.

It also occurs in eastern Polynesia, southern Japan, New Caledonia and Queensland in Australia.

[1][2] C. ramosus has a large, solid, very rugged and heavy shell, of up to 330 mm in length.

It has a relatively globose outline, possessing a short spire, a slightly inflated body whorl, and a moderately long siphonal canal.

[1][2] The Ramose murex inhabits sandy and rubble bottoms near coral reefs, to depths of around 10 m.[2] As is the case in other Muricidae, C. ramosus is a carnivorous predatory species, usually feeding on bivalves and other gastropods.
