## Abstract
Abstract This study aims to analyze the test size and growth type of sea urchins ( Diadema setosum ) on the islands of Kodingareng Lompo and Kodingareng Keke, Makassar City, South Sulawesi Province. This research was conducted for two months, from August to September 2022 on Kodingareng Lompo and Kodingareng Keke Islands, Makassar City, South Sulawesi Province. Kodingareng Lompo represent the seagrass bed ecosystem and Kodingareng Keke represent the coral reef ecosystem. The number of sea urchins caught during the study was 633 individuals in seagrass bed in Kodingareng Lompo and 731 individuals in reef flat in Kodingareng Keke Island. Sample measurement of sea urchins was carried out in situ on the island. Data analysis to determine the size distribution was carried out using a quantitative descriptive approach, including body diameter measurements. The results shows that the test diameter vary from 12,39 - 48,94 mm. The growth pattern of D.setosum sea urchins based on sampling time and station on Kodingareng Keke and Kodingareng Lompo Islands is negative allometric, namely the increase in shell diameter is faster than the increase in weight.
