Na prvi pogled korala izgledajo kot rastline, vendar so v resnici nenavadna vrsta \u017eivali, ki se pritrdijo na skale. Korale, ki se raztezajo po ogromnih obmo\u010djih, so pomemben del zemeljskega ekosistema.<\/p>\n<\/div>\n<p>Znanstveniki so s sateliti Sentinel-2 agencije ESA fotografirali korale na Velikem koralnem grebenu.
