Pseudunela marteli is a species of sea slug, an acochlidian, a shell-less marine gastropod mollusk in the family Pseudunelidae.
The specific name marteli is in honour of author's "big-hearted friend and colleague" biologist Martin “Martl” Heß from Ludwig Maximilian University of Munich, because the species has a large heart-bulb. [2]
Pseudunela marteli is known from Guadalcanal, Solomon Islands and Oyster Island, Vanuatu. [2] The type locality is beach of “Art Gallery”, Honiara, Guadalcanal, Solomon Islands. [2]
External morphology and anatomy of Pseudunela marteli is the same as in Pseudunela viatoris with the following exceptions: [2] Colour of digestive gland is greenish or orange-brownish. [2] Eyes (30–35 μm) are pigmented and well visible externally. [2] Foot length is up to half of the visceral hump. [2] Subepidermal spicules are more abundant in cephalic tentacles, foot and visceral hump. [2]
digestive system: the radula formula is 57–59×1.1.?; rhachidian tooth with 3–4 denticles per side. [2]
reproductive system: the hollow curved penial stylet measures 130 μm in length, the stylet of basal finger is 30 μm long. [2] The ampulla is sac-like; allosperm receptacles are absent in the examined specimen. [2] The albumen and mucus glands are tubular; the membrane gland is sac-like. [2]
Pseudunela marteli is a minute species that lives in the spaces between sand grains in saltwater habitats, and it is thus considered to be a mesopsammic, marine interstitial animal that is part of the meiofauna of marine sands. [2]
