Mean of microsatellites coverage found in the studied cnidarian species. Leiopathes (n =628 count/Mbp), Tanacetipathes (n =364), Eunicea (n =85), Plumarella (n =308), Corynactis (n =106), Amplexidiscus (n =103), Metridium (n =532), Millepora (n =117), Nematostella (n =1047), Hydra (n =1666), A. digitifera (n =1210). The grey circles represent the proportion of microsatellites found. Dashed lines represent the upper and lower 95% confidence interval limits. If only one dashed circle is shown, the lowest C.I. =0.00. Nematostella, Hydra and Acropora digitifera microsatellites were derived from whole genome sequences while only a fraction of the genome was scanned for all other species (PGS). T-tests between coverage of a certain motive type between WGS and PGS were significant for mono- (p =0.01) and di- (p =0.01).
