A Cone Snail, Conus geographus
Previous Image | Next Image
Description: A cone snail, Conus geographus, engulfing a fish with its funnel-shaped mouth. When surrounded by the snail’s mouth, a fish becomes passive, suggesting that the snail releases some sort of sedative into the water. The snail then harpoons the fish and injects a painkilling, paralyzing venom into it, before swallowing it whole.The small tube above the mouth is the snail’s siphon, through which it takes in water for respiration. The siphon also has sensory receptors that allow the snail to detect the scent of its prey.
