Morphological Comparison of Long-snouted Seahorse (Hippocampus guttulatus Cuvier, 1829) Populations in the Black Sea and the Aegean Sea

In this study, a total of 80 specimens belonging to long-snouted seahorse populations distributed in the Black and Aegean Seas were collected from fishermen and analysed. As a result of the analyses, it was determined that there was a statistically significant difference between the populations in terms of total lengths, eye diameters, dorsal fin lengths and body heights values, and in the SIMPER analysis, based on metric measurements and meristic counts, it was calculated that the total difference between the populations was 3.13%.
