Laor is one of the sea worms consumed by local people of Morotai Island as a source of protein. Laor appears seasonally in April and May. Laor will appear on the surface of the waters to do swarming in the morning. The purpose of this research is to study morphological characterization and the content of bioactive compounds in Morotai Island water. The study was conducted from May to August 2019. A sample of Laor obtained from the waters of Tanjung Dehegila, Wayabula, and Bere-Bere district Morotai Island. The extraction of samples using the maceration method with 96% ethanol solvent. Identification of the group of bioactive compounds include alkaloids, flavonoids, saponin, and steroids. The results showed that laor has the characterization of brownish-red body color and blue-greenish, body-level bodies, having hair/legs along the side of the body, and sensor tentacles in the head. Extracts obtained have textures such as pasta, sticky, and yellow, greenish-yellow to reddish-yellow. ELT extract yields 7.8%, ELW as much as 9.4%, and ELB as much as 19.3%. The identifying of the laor bioactive compounds suggests that ELT and ELW contain alkaloid compounds, flavonoids, saponins, and steroids, whereas ELB contains only flavonoid compounds.
