Australian Trumpet: Maximum Snail Species (Overview)

The Australian trumpet snail, scientifically known as Syrinx aruanus, holds a unique title in the mollusk world: it’s the largest extant snail species on Earth!

These shelled gastropod gentle giants, native to the waters of Australia and Papua New Guinea, can reach impressive sizes, with their elongated shells growing up to 30 inches (76 cm) in length and 3 inches (7.6 cm) in diameter.

Their massive size isn’t the only thing that sets them apart. Unlike their smaller, algae-grazing cousins, syrinx aruanus snails are carnivorous, primarily feeding on marine worms and other small invertebrates. These snails’ feeding habits play a crucial role in maintaining the ecological balance of their environment by controlling populations of these organisms.

Absolutely! The Australian Trumpet snail, also known as the False Trumpet, is a giant sea snail and the undisputed heavyweight champion of its snail-shelled kind.

  • Scientific Name: Syrinx aruanus
  • Family: Turbinellidae
  • Size: Up to 72 cm (28 inches) long and can weigh up to 18 kg (40 lbs)

These enormous mollusks are found buried in the sandy or muddy bottoms of tropical and subtropical waters around Australia, particularly in the regions of the Great Barrier Reef. Australian Trumpet snails are shy and nocturnal creatures, spending most of their days hidden from sight.

Here are some interesting facts about the Australian Trumpet snail:

  • It is the world’s largest syrinx aruanus living fossil gastropod (shelled snail) species.

Their impressive size, unique diet, and gentle demeanor solidify the Australian trumpet snail’s position as a true marvel of the underwater world.
