Table 2.
Abundance (N = mean ± standard deviation) of each size class of organisms found in the guts of H. guttulatus and in the sediments in three different habitats (Corallina elongata, sandy bottom and Cladophora prolifera). Data on the total abundance (sum of organisms < 1mm and > 1mm) of organisms found in the guts and sediments in three habitats are published in Table 1, Table 3, respectively, of the article: Trophic flexibility and prey selection of the wild long-snouted seahorse Hippocampus guttulatus Cuvier, 1829 in three coastal habitats [1].
