Conus proximus is the species name a snail from the family of cone snails (genus Conus ), which in the western Pacific Ocean is widespread and feeds on fish .
features
Conus proximus carries a moderately small to medium-sized snail shell that reaches 2.5 to 4.5 cm in length in adult snails. The circumference of the body is conical to conical-cylindrical, the outline is slightly convex and the spindle at the siphonal fasciole is bent slightly to the left. The shoulder is angled to almost angled and occupied with about 12 to 17 tubercles. The thread is medium high and its outline is concave. The Protoconch has about 2 whorls and measures a maximum of 0.8 to 0.9 mm. The seam ramps of the Teleoconch are flat with no spiral grooves increasing to 3 to 4, sometimes with a few additional stripes. The area around the body is covered at the base or even up to the shoulder with wide to narrow spacings, spiraling, often grainy ribs or ribbons.
The basic color of the housing is white to light brown. The body is marked with a yellowish to orange cloud pattern. Spiral rows of brown or orange dots and lines extend from the base to the shoulder, which may be numerous or sparse, but may also be absent. The seam ramps of the first whorls of the Teleoconch have radial stiffeners that match the color pattern of the body, often as highlighted points between the tubercles. The inside of the case mouth is white to pale blue or purple.
The periostracum is thin, translucent, and smooth.
The top of the foot is white to cream-colored, often darker in front and at the edge, in the middle and back section with brown radial spots, in the front section with light brown to dark brown spots that are concentrated in the center and sometimes with a dark brown, dotted or dashed line in front of the edge . The sole of the foot is white with a cream-colored edge. The rostrum is brownish-yellow with brown stripes. The antennae are white with a brown tip, the siphon white to cream-colored and brown with transverse spots, distally lighter and less brown.
distribution and habitat
Conus proximus is common in the western Pacific Ocean from the Philippines to Vanuatu and Fiji . It lives at depths of 25 to 240 m on coarse sand on reefs.
nutrition
Conus proximus eats fish that it harpooned with a radula tooth and paralyzed by the highly effective poison mixture from the poison gland .
