Ocinebrellus
Predatory sea snails of the murex family, subfamily Ocenebrinae.
Ocinebrellus is a genus of predatory marine gastropod mollusks belonging to the subfamily Ocenebrinae within the family Muricidae, which includes murex and rock snails. The genus contains both living and fossil species, with several having been originally described during the 1800s. Recognized species include Ocinebrellus acanthophorus, Ocinebrellus falcatus, Ocinebrellus inornatus, Ocinebrellus lumarius, and the fossil taxa † Ocinebrellus ogasawarai and † Ocinebrellus protoaduncus. Two former species, Ocinebrellus aduncus and Ocinebrellus eurypteron, are now considered synonyms of Ocinebrellus falcatus.

Lore & Background
The genus Ocinebrellus was established by Jousseaume in 1880. Its species are distributed in the Northwestern Pacific, as reviewed by Houart and Sirenko in 2003. The genus includes both living and fossil forms, with species such as Ocinebrellus acanthophorus described by A. Adams in 1863, Ocinebrellus falcatus by G. B. Sowerby II in 1834, Ocinebrellus inornatus by Récluz in 1851, and Ocinebrellus lumarius by Yokoyama in 1926. Two fossil species are recognized: Ocinebrellus ogasawarai (Amano & Vermeij, 1998) and Ocinebrellus protoaduncus (Hatai & Kotaka, 1959).
Reader's Guide
The genus Ocinebrellus holds significance within the subfamily Ocenebrinae as a group of predatory marine snails that have been studied in both Recent and fossil contexts. The species Ocinebrellus falcatus has been the subject of taxonomic synonymy, with Ocinebrellus aduncus and Ocinebrellus eurypteron both considered synonyms. The genus was included in a molecular phylogenetic framework for Ocenebrinae published in 2017, which helped clarify relationships among related muricid taxa. The fossil record of Ocinebrellus contributes to understanding the evolutionary history of the subfamily in the Pacific region. The genus also appears in historical malacological literature, including works by Récluz, Crosse, and Coen, reflecting its long-standing recognition in conchology. Its legacy lies in its role as a representative of the diverse predatory gastropods within the Muricidae, with ongoing taxonomic refinement.

Frequently Asked Questions
What is Ocinebrellus?
Ocinebrellus is a genus of predatory sea snails classified within the murex family Muricidae. These marine gastropod mollusks sit in the subfamily Ocenebrinae, grouping them with other rock snails and murex relatives.
How many species are recognized in the genus Ocinebrellus?
There are four living species and two fossil species currently acknowledged. Two earlier names, Ocinebrellus aduncus and Ocinebrellus eurypteron, have since been folded in as synonyms of other members.
What is the earliest described species in Ocinebrellus?
The oldest catalogued member is Ocinebrellus falcatus, named by G. B. Sowerby II in 1834. Several other species in the genus also received their original descriptions during the 1800s.
Are there fossil species of Ocinebrellus?
Yes, two extinct taxa are known from the fossil record: Ocinebrellus ogasawarai and Ocinebrellus protoaduncus. Both carry the standard dagger symbol (†) to flag their status as no longer living.
What ecological role do Ocinebrellus snails play?
Members of this genus are active predators in marine environments, hunting smaller organisms in their coastal or rocky saltwater habitats. As predatory gastropods within the murex family, they occupy a mid-level position in their local food webs.
