Tonna lischkeana is a species of large, predatory sea snail, a marine gastropod mollusk in the family Tonnidae.
Description & Characteristics
Tonna lischkeana is characterized by its distinctive, bulbous shell, which can grow to a maximum size of 15 centimeters in length. Its shell is typically white or cream-colored, often with brown or reddish-brown markings. The aperture, or opening of the shell, is large and rounded, and the outer lip is usually thickened and flared. Tonna lischkeana has a distinctive, elongated siphon, which is used for breathing and sensing the environment.
Habitat and Occurrence
Tonna lischkeana is a common inhabitant of the Indo-Pacific region, where it is found in shallow, coastal waters, typically at depths ranging from 1 to 50 meters. It is often found in sandy or muddy bottoms, and is sometimes found in seagrass beds. This species is prevalent in the tropical and subtropical zones of the Indo-Pacific, making it a common sight in these marine environments.
Taxonomy
Tonna lischkeana is classified within the Class: Gastropoda, Order: Littorinimorpha, and Family: Tonnidae. This species belongs to a group of marine snails known for their distinctive, often bulbous shells and predatory habits.
Feeding
Tonna lischkeana is a carnivorous snail that feeds primarily on other marine invertebrates, particularly sea urchins. It uses its strong, radula, a ribbon-like structure with rows of teeth, to scrape and crush its prey. The snail’s large size and predatory nature make it an important predator in its ecosystem, helping to regulate populations of sea urchins and other invertebrates.
