This species is small (females up to 1.4 mm, males smaller), elongate (six times as long as wide), eyeless, with short antennae and a sharply pointed pleotelson. The male preoperculum is T-shaped. Although identification of the species is theoretically straight-forward, its small size and the difficulty in finding it present significant challenges.
Distribution and Habitat
M. anisopoda lives interstitially in sand and gravel, both intertidally and sublittorally. Due to its size and the difficulty in finding it amongst the substrate, it is poorly recorded, though it appears to be of south-westerly distribution.
