The Fasciolariidae are a family of small to very large, exclusively marine snails that occur worldwide in tropical and temperate oceans. The representatives of the family are carnivores .

features

The spindle-shaped, double-conical housing of the Fasciolariidae have an elongated thread, an oval housing mouth and a medium-long to long siphon channel. In adult snails, they are 1 to 60 cm tall. The columella can be smooth or have some spiral folds at the base. The housings are often reddish in color. The operculum is horny, thick and ovoid to claw-shaped. The radula has narrow central teeth with three cusps and wide lateral teeth with numerous comb-like cusps.

The bright red snails have a small, narrow head with short antennae, at the base of which the eyes are outside, and a well-developed sipho . The proboscis can be extended very far.

The animals are separate sexes with internal fertilization. The eggs develop in egg capsules from which, in most species, ready-made snails hatch, in some cases free-swimming Veliger larvae, which only metamorphose into snails after a pelagic phase .

Way of life, occurrence and distribution

The Fasciolariidae are distributed worldwide in all tropical and temperate seas. The family has the greatest biodiversity in the Indo-Pacific . They live in the marine environment on sand, mud or gravel. The types of fasciolariidae are carnivores, which largely from snails , clams , polychaete worms and barnacles feed.

The Fasciolariidae include the species Pleuroploca gigantea , which lives in the western Atlantic, and the real tulip snail ( Fasciolaria tulipa ) that occurs there.

Systematics

According to Bouchet and Rocroi (2005), the Fasciolariidae family is one of six families in the superfamily Buccinoidea . They divide the family Fasciolariidae into three subfamilies:

  • Fasciolariinae Gray, 1853
  • Fusininae Wrigley, 1927 - Synonyms: Fusinae Swainson, 1840 (inv.); Cyrtulidae MacDonald, 1869; Streptochetinae Cossmann, 1901
  • Peristerniinae Tryon, 1880 - Synonym: Latiridae Iredale, 1929
