Eubranchus vascoi

Definition
Eubranchus vascoi is a species of marine gastropod mollusk belonging to the family Eubranchidae. It is a type of nudibranch, commonly referred to as a sea slug.

Overview

• Taxonomic classification

  • Kingdom: Animalia
  • Phylum: Mollusca
  • Class: Gastropoda
  • Subclass: Heterobranchia
  • Order: Nudibranchia
  • Family: Eubranchidae
  • Genus: Eubranchus
  • Species: E. vascoi

• Discovery and description
  The species was formally described in the scientific literature in the early 2010s. It is listed as a valid species in the World Register of Marine Species (WoRMS).

• Distribution
  E. vascoi has been recorded from the northeastern Atlantic Ocean, particularly along the coasts of the Iberian Peninsula (Portugal and Spain). Additional records, if any, are not widely documented.

• Habitat and ecology
  Like other eubranchid nudibranchs, it is a benthic organism that inhabits shallow marine environments, often associated with the hydroids on which it feeds. Precise details of its diet and ecological interactions have not been extensively published.

Etymology / Origin
The specific epithet vascoi is likely a patronym honoring a researcher, collector, or individual with the surname “Vasco.” The original description of the species would contain the formal dedication, but the exact origin is not confirmed in the available summaries.

Characteristics

• Morphology: E. vascoi is a small nudibranch, typically measuring a few millimeters in length. It possesses the characteristic cerata (finger‑like dorsal appendages) arranged in rows along its body.
• Coloration: Descriptions note a translucent or pale background color with possible orange or reddish pigmentation on the cerata tips, similar to other congeners, but detailed coloration patterns are not comprehensively documented.
• Anatomy: As a member of Eubranchidae, it has a smooth rhinophore pair, a simple oral veil, and a radula adapted for feeding on cnidarians. Specific radular tooth morphology for E. vascoi is not publicly detailed.
