Charonia lampas is a species of predatory sea snail, a marine gastropod mollusk in the family Charoniidae. [1]
This marine species has a wide distribution: the North Sea, the North Atlantic Ocean (Azores, Madeira, the Canaries, Cape Verdes), the Atlantic Ocean (off the African coasts), the Mediterranean Sea, and the Indian Ocean (off Madagascar, the East coast of South Africa).
The maximum recorded shell length is 390 mm. [2] The large shell measures up to 400 mm on mainland locations, to 200 mm off island and seamount sites. The protoconch is multispiral, normally eroded except on very juvenile specimens. The teleoconch consists of 8–9 whorls with a moderately high, conical spire and convex whorls, the last one ample and making up slightly more than two-thirds of the total height. The spire whorls are vaguely shouldered, with very flat spiral cords separated by poorly defined, rather narrow interspaces, the shoulder covered by a much broader and flatter cord and commonly, but not always, bearing a spiral series of knobs, paralleled to the abapical side by lesser flat cords with or without spiral rows of knobs. The large aperture is oval in shape, with an elaborate peristome. The outer lip is flaring, thickened at a short distance from the edge and with internal denticles. The inner part of the peristome shows an appressed parietal callus continued into a foliated columellar callus, which has a raised edge overhanging the siphonal canal on large specimens, and bears indistinct ridges towards the edge. The colour pattern is very characteristic, with articulated spiral bands of light patches on the knobs and dark brown in the interspaces, alternating with medium brown uniform bands. The peristome is white with dark brown denticles on the outer lip and a brownish to reddish hue on the edge of columellar callus. [1]
Minimum recorded depth is 8 m. [2] Maximum recorded depth is 50 m. [2]
Murex is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod molluscs in the family Muricidae, commonly called "murexes" or "rock snails".
Charonia is a genus of very large sea snail, commonly known as Triton's trumpet or Triton snail. They are marine gastropod mollusks in the monotypic family Charoniidae.
Bolinus brandaris, and commonly known as the purple dye murex or the spiny dye-murex, is a species of medium-sized predatory sea snail, an edible marine gastropod mollusk in the family Muricidae, the murex snails or the rock snails.
The gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group.
Ranella olearium, common name the wandering triton or the little frog triton or olive trumpet, is a species of large sea snail, a marine gastropod mollusc in the family Ranellidae, the tritons.
Tonna galea, commonly known as the giant tun, is a species of marine gastropod mollusc in the family Tonnidae. This very large sea snail or tun snail is found in the North Atlantic Ocean as far as the coast of West Africa, in the Mediterranean Sea and the Caribbean Sea. The species was first described by Carl Linnaeus in 1758.
Ocenebra is a genus of predatory sea snails, marine gastropod mollusks in the subfamily Ocenebrinae of the family Muricidae, the murex and rock snails.
