Melo melo, common name the Indian volute or bailer shell (also spelled baler), [3] is a very large edible sea snail, a marine gastropod mollusc in the family Volutidae, the volutes. [1]
The distribution of this species is restricted to Southeast Asia, from Burma, Thailand and Malaysia, to the South China Sea and the Philippines. [1] [2]
This large sea snail is known to live in littoral and shallow sublittoral zones. It usually dwells in muddy bottoms at a maximum depth of nearly 20 m. [2]
Melo melo is known to be carnivorous, as laboratory experiments have shown. It is a specialized predator of other continental shelf predatory gastropods, notably Hemifusus tuba (Melongenidae) and Babylonia lutosa (Buccinidae). [4] It is also a known predator of the dog conch, Strombus canarium (Strombidae). [5]
The maximum shell length of this species is up to 275 mm, commonly to 175 mm.
The notably large shell of Melo melo has a bulbous or nearly oval outline, with a smooth outer surface presenting distinguishable growth lines. The outside of shell colour is commonly pale orange, sometimes presenting irregular banding of brown spots, while the interior is glossy cream, becoming light yellow near its margin. [2] The columella has three or four long and easily distinguishable columellar folds. [2] It has a wide aperture, nearly as long as the shell itself, yet this species is known to have no operculum. [2] The shell's spire is completely enclosed by the body whorl, which is inflated and quite large, and has a rounded shoulder with no spines. The apex is of smooth type. [2]
This volute is known to produce pearls; however the Melo melo pearl has no nacre, unlike the pearl of a pearl oyster. The GIA and CIBJO now simply use the term 'pearl' (or, where appropriate, the more descriptive term 'non-nacreous pearl') when referring to such items, rather than the previously-used term 'calcareous concretion' [6] [7] and, under Federal Trade Commission rules, various mollusc pearls may be referred to as 'pearls' without any qualification. [8] The melo pearl is created by the mollusc in the same way as other pearls are created by other molluscs.

This volute is often collected for food by local fishermen. The shells are also often used as decoration, or as scoops for powdery substances in local markets. [2]
The shell is also traditionally utilized by the native fishermen to bail out their boats, therefore it is commonly called "bailer shell". [2]
Conch is a common name of a number of different medium-to-large-sized sea snails. Conch shells typically have a high spire and a noticeable siphonal canal.
Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may generally refer to any of the Strombidae but sometimes is used more specifically to include only Strombus and Lambis. The family currently includes 26 extant, and 10 extinct genera.
Aliger gigas, originally known as Strombus gigas or more recently as Lobatus gigas, commonly known as the queen conch, is a species of large sea snail, a marine gastropod mollusc in the family of true conches, the Strombidae. This species is one of the largest molluscs native to the Caribbean Sea, and tropical northwestern Atlantic, from Bermuda to Brazil, reaching up to 35.2 centimetres (13.9 in) in shell length. A. gigas is closely related to the goliath conch, Lobatus goliath, a species endemic to Brazil, as well as the rooster conch, Aliger gallus.
Strombus is a genus of medium to large sea snails, marine gastropod molluscs in the family Strombidae, which comprises the true conchs and their immediate relatives. The genus Strombus was named by Swedish Naturalist Carl Linnaeus in 1758. Around 50 living species were recognized, which vary in size from fairly small to very large. Six species live in the greater Caribbean region, including the queen conch, Strombus gigas, and the West Indian fighting conch, Strombus pugilis. However, since 2006, many species have been assigned to discrete genera. These new genera are, however, not yet found in most textbooks and collector's guides.
Volutidae, common name volutes, are a taxonomic family of predatory sea snails that range in size from 9 mm to over 500 mm. They are marine gastropod mollusks. Most of the species have no operculum.
Melo amphora, common name the Diadem volute, is a very large sea snail, a marine gastropod mollusc in the family Volutidae, the volutes.
Melo is a genus of extremely large sea snails, marine gastropod molluscs in the family Volutidae, the volutes. Because of their huge ovate shells, these snails are often known as "bailers" or "melons".
Melo miltonis, the southern bailer or southern baler, is a large sea snail, a marine gastropod mollusc in the family Volutidae, the volutes.
Strombus pugilis, common names the fighting conch and the West Indian fighting conch, is a species of medium to large sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
Lentigo lentiginosus, the silver conch, is a species of medium-sized sea snail, a marine gastropod mollusc in the family Strombidae, the true conchs.
Laevistrombus canarium is a species of edible sea snail, a marine gastropod mollusc in the family Strombidae. Known from illustrations in books dating from the late 17th century, L. canarium is an Indo-Pacific species occurring from India and Sri Lanka to Melanesia, Australia and southern Japan. The shell of adult individuals is coloured from light yellowish-brown to golden to grey. It has a characteristic inflated body whorl, a flared, thick outer lip, and a shallow stromboid notch. The shell is valued as an ornament, and because it is heavy and compact, it is also often used as a sinker for fishing nets.
Conomurex luhuanus, commonly known as the strawberry conch or tiger conch, is a species of medium-sized sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. C. luhuanus is found in sandy habitat among corals in the Indopacific region. They feed on algae or detritus, move with a modified foot, and have complex eyes compared to other gastropods.
Cymbium pachyus, commonly known as the dilated baler volute, is a species of sea snail, a marine gastropod mollusc in the family Volutidae, the volutes.
Labiostrombus epidromis, common name the swan conch, is a species of sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.

Canarium labiatum, common name the Samar Conch, is a species of sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
Canarium mutabile, common name the variable stromb, is a species of sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
