Knowra Muricidae Muricidae Muricidae is a large family of predatory marine gastropods, commonly called murex snails or rock snails. Many species have sculptured shells and prey on other mollusks.
Drilling predation : A feeding strategy in which a predator bores through prey shells to reach soft tissues. Many muricids drill mollusk shells, creating access to otherwise protected prey.
Tyrian purple : A deep purple dye historically extracted from certain marine snails, especially the spiny dye-murex. Ancient production of this costly dye relied on secretions from muricid species.
Gastropoda : The largest class of mollusks, including snails and slugs, typically characterized by a muscular foot and torsion. Muricidae is nested within this major molluscan class.
Chicoreus ramosus : A large Indo-Pacific muricid snail with a shell bearing conspicuous branched spines. Its elaborate shell is a striking example of muricid form.
Radula : A toothed, ribbon-like feeding structure used by most mollusks to scrape, cut, or rasp food. Muricids use radular teeth during feeding and shell-boring attacks.
Hexaplex trunculus : A Mediterranean muricid snail known as the banded dye-murex. This species was one of the shellfish used in ancient purple-dye production.
Neogastropoda : A diverse clade of mostly carnivorous marine gastropods, including whelks, cone snails, and muricids. This evolutionary group contains Muricidae and many related predatory snails.
Nucella lapillus : A small muricid snail of the North Atlantic rocky shore, also called the dogwhelk. This familiar intertidal species demonstrates shell-boring predation on barnacles and mussels.
Shell sculpture : The ribs, spines, ridges, and other raised patterns on a mollusk shell. Muricid shells often develop prominent sculpture that varies among species.
Bolinus brandaris : A Mediterranean muricid snail commonly called the spiny dye-murex. Its glandular secretion supplied a major source of Tyrian purple.
