#1206 - Melo miltonis - Southern Baler
A very large carnivorous sea snail that we found at Point Peron the other day, where it was engrossed with devouring a Turban Shell (Turbo torquatus).
Balers have been used to scoop water out of canoes, which is how they got the common name, and while ‘melo’ means ‘apple-shaped’ it’s also been applied to the Latin for watermelons, eggplants, and other large oval objects.
Balers are generally nocturnal, burying themselves in the sand during the day, and feed on other molluscs including scallops, turban shells, tritons and even other volutes. They seize it with their large colourful foot and plugs the prey’s aperture, essentially smothering it. This one clearly found itself too far from open ground to bury itself and eat in peace, and was resting upside down on the rock platform just offshore.
When breeding, Baler shells lay a first layer of eggs onto a rock or another shell and then stack more eggs on top, layer by layer, to form a hollow case. enabling the water flow to penetrate and ensure circulation around the eggs. An egg-case can contain more than 100 young snails, who are ready to hunt their own prey when they emerge.
