I’m excited to offer this beautiful specimen of Chicoreus riverai, a recently described species from the Tortuga Terrace and Pulley Ridge region of the Florida Keys. This species was named after me, Captain Randy Rivera, for discovering portions of the unique Tortuga Terrace molluscan fauna during my commercial lobster fishing operations aboard the F/V AVA PILAR and for providing important material used in the scientific study of these remarkable deep-water species.
This particular specimen was personally collected by me in February 2026 from a baited commercial lobster trap set in 240–300 feet of water and represents an excellent example of this recently described muricid.
Following the original description by Petuch and Berschauer, Chicoreus riverai is distinguished by its compact, heavily sculptured shell, broad rounded body whorl, elevated spire, and spectacular frondose varices. The species possesses six closely spaced varices ornamented with delicate branching spines, a proportionally short siphonal canal, and the characteristic orange to reddish-orange protoconch and early whorls that readily separate it from closely related Gulf species.
This specimen displays exceptional orange coloration with lighter cream highlights accentuating the intricate frondose sculpture. The varices are beautifully developed, producing an impressive three-dimensional appearance, while the vivid orange protoconch and early whorls remain well preserved. The delicate branching spines and compact form make this an outstanding representative of the species.
Condition
This is a beautiful collector-quality specimen with excellent color and outstanding overall presentation. The intricate frondose sculpture and elevated spire are well preserved, and the shell displays nicely developed varices throughout. Minor imperfections associated with commercial trap collection may be present but do little to detract from its exceptional display value. Please review all photographs carefully, as they are an important part of the description and accurately represent the specimen being offered.
