Overview

Distribution

Range Description

This species occurs primarily in the north-west Indian Ocean from the central Red Sea to Somalia; there is a separate population off South India and Sri Lanka; a further population may occur off the north of Madagascar (Röckel et al. 1995). However, the Madagascan populations need verification, since these have not been confirmed since 1995; therefore these records are questionable (G. Raybaudi pers. comm. October 2011).

The EOO, AOO and number of locations exceed the thresholds for criteria B1 and B2 by a considerable margin.

Habitat and Ecology
This species occurs in depths of 20-100 m, mainly on sand. Adults of the species will grow to approx 65 mm although they will typically be less than this (Röckel et al. 1995). The species has planktotrophic larval development, which explains its widespread distribution.

Population

Population
There is no population information for this species. The main population occurs off India where it is known in abundant numbers from dredging. Presence is uncertain in the Red Sea and the species is rare in Somalia. Dredging in Indian waters has decreased from past levels, so the main population in India is likely to be stable. However, status of other populations is uncertain (G. Raybaudi pers comm. October 2011).

Wikipedia

Conus bayani

Conus bayani, common name the Bayan's cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.[1]

Like all species within the genus Conus, these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.
