Stubby Dendronotid

Dendronotus subramosus

Dendronotus subramosus is a small sea slug characterized by its distinctive shape and coloration. It can reach a maximum length of 3.3 cm and is recognized for its shell-less body, typical of nudibranchs. This species is found along the Pacific Ocean coast of North America, ranging from Bamfield on Vancouver Island, British Columbia, to Islas Coronado in Baja California, Mexico. It inhabits benthic environments, often residing in shallower waters, with most recorded sightings occurring at depths shallower than 40 meters. Feeding primarily on the hydroid Aglaophenia, Dendronotus subramosus has adapted to consume this specific prey, which contributes to its ecological niche. The species exhibits simultaneous hermaphroditism, allowing individuals to mate with one another. During mating, both individuals engage in a behavior where they attempt to induce the other to act as a male or female, with the dominant one penetrating the body wall of the other. Divers may encounter this species at various dive sites, where it can be observed slowly moving along the substrate. Its cryptic coloration may help it blend into its surroundings, making it essential for divers to be attentive to spot it. While there are no specific conservation measures noted, its IUCN status is Not Evaluated.
