📖 1. Overview
The European lancelet is a small chordate that lives buried in coarse sediment in shallow waters of the northeastern Atlantic, Mediterranean, and western Indian Ocean.
🦴 2. Anatomy & Morphology
It has extensive fin-like structures along its body that allow it to swim short distances. Fine tentacles surrounding the mouth help gather food.
🔍 3. Ecology & Behavior
Buried in coarse sediment with less than 10% mud content, it non-selectively filter-feeds on detritus, phytoplankton, and copepods in the water. Sexes are separate, and eggs develop into planktonic larvae before settling as benthic adults.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
