Spergo
''Spergo'' is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae. Description The large, thin shell is nearly destitute of sculpture. It shows an unrecurved columella, a short, wide, straight siphonal canal, a wide shallow emargination representing the anal notch, and generally feeble anal fasciole, except in the very young. There is a sharp outer lip, unarmed aperture, and a sinusigera protoconch. The animal has a muzzle formed by a stout squarely truncated rostrum opening into a capacious pharynx, provided internally with a degenerate proboscis not capable of extrusion beyond the oral orifice, with a poison gland and a degenerate radula. Eyes are present and functional. The tentacles are low-seated, stout, and clavate. The operculum is absent. The dentition resembles that of Bela. This form resembles ''Pleurotomella'', Verrill, from which it differs in the character of the rostrum and pharynx, in the possession of eyes, in its straight wide s ...

Spergo Glandiniformis
''Spergo glandiniformis'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell reaches 40 mm. (Original description) The large, slender shell is glandiniform, with a typical brown sinusigera protoconch of 3½ whorls, followed by 8 normal whorls. The color is pale madder brown, more or less zoned in harmony with lines of growth, and with a peripheral and basal spiral paler band feebly indicated. The columella in the young is stained with a darker brown, or pinkish white in the full-grown shell. The spire is rather pointed. The apical whorls are sculptured with incised spiral grooves below the shoulder and with numerous small oblique riblets over which the grooves run. The space between the shoulder and the suture behind it is slightly impressed, smooth, or crossed by distant low sharp wrinkles, very narrow and not corresponding to the ribs. All this sculpture becomes rapidly obsolete, and on the greater part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Raphitomidae
Raphitomidae is a family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". ''Malacologia'' 47(1-2). . 397 pp. Bouchet, Kantor ''et al''. elevated in 2011 the subfamily Raphitominae (which at that point had been placed in the family Conidae) to the rank of family. This was based on a cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. The family was found to be monophyletic. Description The Raphitomidae is the largest, most diverse and most variable taxon in the Conoidea, with the greatest number of species and the largest ecological range (from the tropics to the pole) and largest vertical range (intertidal to hadal depths). The shells of species in the Raphitomidae are very variable in shape (buccinoid to ovate, elongate-fusiform, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
