Tonicia is a genus of chitons in the family Chitonidae. The genus was recently restricted to include only 12 New World species, with the more species-rich and exclusively Old World subgenus Lucilina Dall, 1882, being elevated to a separate genus. [1] Of these 12, ten species are found in the eastern Pacific, one in the Magellan province (southern Chile, Argentina and Falkland Islands) and one in the Caribbean Sea (Florida to Barbados). However, a study published in 2019 which used molecular systematics to compare the eastern Pacific Tonicia species suggested that there are only 9 extant species in the eastern Pacific. [2]

<i>Strombus</i> Genus of gastropods

Strombus is a genus of medium to large sea snails, marine gastropod molluscs in the family Strombidae, which comprises the true conchs and their immediate relatives. The genus Strombus was named by Swedish Naturalist Carl Linnaeus in 1758. Around 50 living species were recognized, which vary in size from fairly small to very large. Six species live in the greater Caribbean region, including the queen conch, Strombus gigas, and the West Indian fighting conch, Strombus pugilis. However, since 2006, many species have been assigned to discrete genera. These new genera are, however, not yet found in most textbooks and collector's guides.
