C. gorillae are box-jellies with many pale yellow tentacles arising from a single stalk at each lower corner of the bell, which is generally fist-sized or larger. The umbrella is fairly rigid and transparent, not granular, with a number of brown vertical stripes. Rather uncommon, this deeper water species may be caught in trawl nets and has been recorded stranded. The sting of this species is not known to be fatal, but this is most likely due to its rarity.
C. gorilla is a large, poorly known, cuboid medusa that has a wide, flat-topped bell approximately 120 mm in diameter. The jelly is thick and rigid, while the lower part of the bell is thinner, composed of sixteen gelatinous structures that are connected by a web-like velarium. It has four gastric pouches, each bearing a two finger-shaped processes hanging down into the subumbrellar space. Four gonads are attached like bunches of grapes beneath the top of the subumbrellar cavity.
Found along the west coast of southern Africa (particularly Namibia)
