Short description आकृति विज्ञान | मौरफोमैटरिक्स

Oryzias sakaizumii is distinguished from all other congeners including O. latipes that are distributed throughout east Asia by the following combination of characters: distribution of melanophores, dense network of melanophores along each scale margin on the body surface in both sexes; depth of notch in membrane between dorsal-fin rays 5 and 6 less than half the length of rays in males; distinctive irregular black spots on the posterior portion of body lateral; and several silvery scales in patches on the posterior portion of the body (Ref. 89067).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)
