This is another version of that. This is a sea dragon, and the one on the bottom, the blue one, is a juvenile that has not yet swallowed the acid, has not yet taken in the brown-green algae pond scum into its body to give it energy.
Ovo je druga verzija toga. Ovo je morski zmaj, a onaj na dnu, plavi,  je mladunče koje još nije progutalo kiselinu, nije još unijelo smeđezeleni talog jezerskih algi u svoje tijelo da mu daju energiju.
