The iron-gray cone snail ( Conus glaucus ) is a snail belonging to the cone snail family (genus Conus ) that is found in the southwestern Pacific Ocean .
features
Conus glaucus carries a medium-sized to moderately large, moderately firm to moderately heavy snail shell , which in adult snails reaches 3 to 6.5 cm in length. The circumference of the body is bulbous, conical to broadly conical, occasionally slightly pear-shaped, the outline at the apex is convex, but less towards the base, sometimes concave on the left at the base. The shoulder is almost angled to rounded. The thread is low, its outline almost straight to concave. The seam ramps of the Teleoconch are slightly convex to slightly concave with spiral stripes. The body is covered at the base with prominent spiral ribs of varying width.
The basic color of the case is bluish-gray. The circumference of the body is covered with spiral rows of fine brown dots and lines, with white stripes often missing in between. The base, siphonal fasciole, and basal portion of the columella are not spotted and are sometimes brown. The suture ramps of the first whorls of the teleoconch are brown, and the later suture ramps have blackish-brown to black radial stripes or spots that sometimes extend to the perimeter of the body where they are lighter and form axial stripes. The inside of the case mouth is pale brown in almost adults and bluish-white in adults.
The upper side of the foot is gray, with orange-colored edges in front, underlaid brown in the rear half and with a white spot below the tiny operculum . The sole of the foot is beige with dark spots, the rostrum is dull orange. The feelers are beige, the Sipho brown.
distribution and habitat
Conus glaucus is widespread in the seas of the Indomalayis and in the western Pacific Ocean , off the Philippines , Indonesia , Papua New Guinea , the Solomon Islands and Vanuatu . It lives in the intertidal zone and a little below, mostly on sand-covered surfaces.
nutrition
The feeding behavior and prey of Conus glaucus have not yet been directly investigated. Other species of the subgenus Dendroconus with similar fangs , such as Conus betulinus , eating polychaete (Polychaeta).
