[edit] Distribution
Scissurellids live world-wide in most seas, intertidal down to abyssal depths, including around hydrothermal vents.
[edit] Shell description
Scissurellids are small or minute, thin, white, and varying in shape from auriform to depressed trochiform or turbinate, with either a slit in the outer lip, or a hole just behind the aperture, and this is usually situated within a spiral groove, termed the selenizone.
[edit] Systematics
There are about 169 living described species of Scissurellidae, but the diversity of scissurellids is still far from being completely assessed (approximately 60 collected species await description).[1] The monophyly of the family is questionable. [2]There are about twenty-five genera divided into five subfamilies[3], including:
- Anatoma Fleming, 1828
- Anatomus
- Incisura Hedley, 1904
- Maxwellella
- Schismope
- Scissurella d'Orbigny, 1824
- Scissurona Iredale, 1824
- Sinezona Finlay, 1927
- Sukashitrochus
- Sukashitrochus Habe and Kosuge, 1964
- Sutilizona
- Sutulizona
- Temnocinclis
- Temnozaga
- Triassurella
