The Aporrhaidae are a family of small to medium-sized, exclusively marine snails with 6 recent species that feed as filter feeders.
features
The right-hand twisted, solid housing of the Aporrhaidae have a high conical thread with about 8 convex passages and at the mouth of the housing, which is drawn into a siphon channel, a widened outer lip with finger-like extensions. There is no navel. The horny operculum is small.
Way of life, occurrence and distribution
The Aporrhaidae live in cooler seas, mostly at greater depths on sand and mud, where they burrow and filter detritus from the respiratory water . The pelican foot , which also occurs in the North Sea , lives up to a depth of 10 meters. The snails are separate sexes with internal fertilization. Veliger larvae hatch from the eggs and go through a longer pelagic phase.
Systematics
According to Bouchet and Rocroi (2005), the Aporrhaidae family is one of four recent families in the Stromboidea superfamily , to which there are four more fossil families. They divide the family Aporrhaidae into two recent subfamilies:
- Aporrhainae Gray, 1850 - Synonym: Chenopidae Deshayes, 1865
- Arrhoginae Popenoe, 1983 - Synonyms: Alariidae Koken, 1889 (invalid); Dicrolomatidae Korotkov, 1992
These each include a genus, Aporrhais and Arrhoges .
