Description

Founded by Bertsch and Johnson in 1982, the Halgerda terramtuentis has an opaque white slug-like physique. [3] The body’s morphology includes a flat jelly-like texture, and solid yellowish-gold lines running throughout the mantle; located also at the edge of the muscular foot. [4] Their gills are of a whitish hue with black detailing similar to spots. [3] Additionally, the prominent white pustules emerge where the lines consistently cross. [4] The Nudibranch’s length ranges from 15 mm to 50 mm long. [3]

The Halgerda terramtuenti are hermaphrodites that mate within combat of one another. [5] The disadvantaged Nudibranchi’s mantle is then penetrated with reproductive material from the victor. [4] Following the life cycle, they lay groups of eggs coated in yellowish mucus, that develop into veliger larvae and subsequently, full-grown adults capable of reproduction. [6]

Distribution

In Eastern Central Pacific, the Halgerda terramtuentis is endemic to five major Hawaiian islands: Hawaiʻi, Maui, Lanaʻi, Oʻahu, and Kauaʻi; including the remote islands of Niʻihau and the French Frigate Shoals. [6] These sea slugs are found five to thirty meters underwater near overhanging rock foundations and underwater caves. [7] [8]
