Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This species generally occurs between 10-240 m but can be found as deep as 600 m in areas of Hawaii. However, this species more typically found in 20-60 m depths (G. Raybaudi and S. Veldsman pers. comm. October 2011), so it is possible that the 600 m depth record is in error. It can occur on several substrates including; sand, sand mixed with rubble, and coralline gravel. The typical size for adult shells of this species is between 40 and 75 mm in length (Rockel et al. 1995).

This is a planktotrophic species and therefore widely distributed. It also occurs in granulous form variation (G. Raybaudi pers. comm. October 2011).

Conus circumactus

Conus circumactus is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.[2]

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.

Description

The size of an adult shell varies between 35 mm and 75 mm. The smooth shell is rather thin. The spire is low-conical and contains revolving striae, usually maculated with chestnut. The body whorl is striate below. The color of the shell is yellowish or light chestnut, with large white blotches forming a band at the shoulder and another on the middle, encircled by narrow chestnut lines, which are often broken up into small dots . The color of the base and the aperture is usually violaceous. In Conus cinctus, Swainson 1822, the narrow chestnut lines are continuous, the white blotches and interior of aperture are more or less suffused with rose-color. [3]

Distribution

This species occurs in the Pacific Ocean and along Australia.
