ABSTRACT Lingula anatina Lamarck, 1801 is a genus of the phylum Brachiopoda which is a primitive invertebrate known as a living fossil. Lingula anatina Lamarck, 1801 or what is known as the lantern clam is one of the macrobenthos that make up the muddy intertidal ecosystem. Until now, no research has been carried out regarding the Growth Pattern of Lingula anatina Lamarck, 1801 on the Ulee Lheue Mangrove Beach. The aim of this research is to determine the growth pattern of Lingula anatina Lamarck, 1801 using a size distribution approach, length-weight relationship, condition factors, and water quality parameters at Ulee Lheue Mangrove Beach, Kuta Raja District, Banda Aceh City. This research was carried out in November 2022 at Ulee Lheue Mangrove Beach. The method used in this research is purposive sampling. Sampling is carried out once a week for one month. The research results showed that the average size distribution of Lingula anatina Lamarck, 1801 was 40.78 mm. The length and weight relationship of Lingula anatina Lamarck, 1801 on the Ulee Lheue Mangrove Beach shows a positive allometric and also negative allometric pattern. The condition factor at Ulee Lheue Mangrove Beach has a value of = 1 which indicates Lingula anatina Lamarck, 1801 is in a fat condition.
