Due to its unusual appearance and also dimension, many individuals describe the worm as unusual- like or horrible.

The Antarctic scale worm lives deep on the sea flooring where it hides itself under debris and also assaults close-by pantopoda sea spiders and also potentially various other aquatic life.

Antarctic Scale Worm Scientific Name

Antarctic scale worms are sea- home annelids. Annelids are fractional worms like earthworms, caterpillars and also greater than 900 species of scale worms that live undersea. The animal’s scientific name is Eulagisca gigantea, “gigantea” standing for the worm’s massive dimension in contrast to lots of aquatic worms.

The gold scale worm was identified and also called in 1939 by Charles Carmichael Arthur Monro of Scotland, a zoologist in the British Gallery of Nature.

Antarctic Scale Worm Appearance & & Habits

Antarctic scale worms mature to a large 8 inches (20 centimeters) in size. They are essentially level from their back to their abdominal area. However throughout the back or abdominal area the worms depend on 4 inches (10cm) large.

These sea animals have 40 body sectors covered by 15 sets of ranges called elytra. In general, their head is oblong formed.

The worm’s body and also head are grey- brownish in shade. Thousands of yellow- gold bristles called chaete expand outside from its body in tufts on each side along its size. The shade of the body and also its safety ranges assist it conceal in debris on the sea flooring. Its bristles aid thrust the worm via the water like legs in addition to motion of its ranges. It additionally utilizes these motions to browse along surface areas like the sea flooring and also hide itself in the debris.

Antarctic scale worms live singular lives, other than throughout recreation. It is both protective and also hostile, being a competent killer of pantopoda sea spiders.

When launched right into the water, the female’s eggs are fed by the male’s sperm. The fed eggs usually wander easily in the water like plankton. These eggs become larva. After the larva phase their bodies extend to the grown-up dimension.
