Conus aurisiacus is a marine snail that is native to the seas off the Philippines and Indonesia ( Maluku , Sulawesi ). Like all members of the genus Conus , Conus aurisiacus preyes on its victims with poison . It can also be dangerous to humans. Conus aurisiacus was first described by Carl von Linné in 1758.
description
Conus aurisiacus is a medium to large cone snail. Adult specimens reach a maximum length of 95 mm, but mostly they stay smaller. The size of the case is given as 43 mm to 95 mm. The basic color of the bulbous, conical or conical housing is interspersed with white with variable pink. Slight circumferential furrows can be seen on the shell. The last handle usually has two to three variable width, pink-brown spiral bands. In addition, there are spiral bands with alternating white lines and reddish to blackish-brown dots of different sizes and numbers, as well as darker bands. The base is yellow, the tip white.
The thin, translucent, smooth periostracum is pale yellow.
The radula teeth are described as relatively long, the ratio of shell to tooth length is 11: 1. The teeth have two small barbs at the tip and a third, long, backward-pointing, distally curved barb. The saw and spur at the base are missing.
Habitat and way of life
Conus aurisiacus lives in small caves on sandy and gravelly slopes in water depths of about 25 meters. The casings are also collected at a great depth of 150 m. The structure of the radula teeth suggests that it is a piscivore ( fish-eating ) species.
