--------------------

Syngnathidae fossils can be dated back to the Pliocene period found near Italy. Similarly, such as a tubular moth and long cylindrical bodies can be compared from the fossil records and extant species today. It belongs within the order Gasterosteiformes, meaning boney belly. Their bodies have boney plates used for protection. In the Yucatan pipefish 22\-26 dorsal fin rays, pectoral rays 11\-12, 3 anal fin rays can be observed (Herald and Dawson 1972\). Within the male population, the brood pouch can hold 5\-16 eggs. Compared to the gulf pipefish, Syngnathus *s. makaxi* has less trunk rings and it is significantly smaller in length than the gulf pipefish (Herald and Dawson 1972\). Length varies from 52 mm to 154 mm and average weight is about. 3 grams (Wilson, Ahnesjo, Vincent and Meyer 2002\).
