Cymatium is a genus of small to large predatory sea snails, marine gastropod mollusks in the family Ranellidae, the tritons.
This genus has numerous species, perhaps as many as 100, some of which have a world-wide distribution. The genus has been divided into at least 10 subgenera. Some authors have elevated the subgenera into genera, but this is by no means universally accepted.
These sea snails have separate sexes. They lay egg capsules. After hatching the larvae have a planktonic stage that can (in some species) last several months; this is what enables the very widespread distribution seen in certain species, as the planktonic larvae can be carried great distances before settling to the sea floor.
Subgenera
There are at least 10 subgenera within the genus Cymatium [1]. These are treated by some authors as if they were genera.
- Cymatium Röding, 1798, type species: Cymatium femorale
- Monoplex G. Perry, 1811, type species: Cymatium parthenopeum
- Gelagna Schaufuss, 1869, type species: Cymatium succinctum
- Ranularia Schumacher, 1817, type species: Cymatium gutturnium
- Gutturnium Mørch, 1852, type species: Cymatium muricinum
- Reticutriton Habe and Kosuge, 1966, type species: Cymatium pfeifferianum
- Linatella Gray, 1868, type species: Cymatium cutaceum
- Lotoria Emerson and Old, 1963, type species: Cymatium perryi
- Septa Perry, 1810, type species: Cymatium rubeculum
- Turritriton Dall, 1904, type species: Cymatium gibbosum
