morsko stabalce | sea tree

Sea tree, yellow cornea Yellow cornea is a species of corals with soft skeleton. The polyps of this coral build colonies in the form of a yellow branched fan tree. The inner part is horny, and the surface covers mucous membrane with small white-yellow polyps. The colony can grow to a diameter of 50 cm. It is mainly located on the rocky walls in areas of strong currents, at depths of 10 to 150 meters where it feeds on plankton brought in by the current. This colonial coral builds large branched colonies that grow on one plane. Polyps are not big and are mostly located on the opposite side of branch on the same plane as the colony is. Their color varies from yellowish, pale-ocher to warm orange and is not a product of their sclerite, but of living tissue therefore dried and preserved specimens lose their color. The colony grows slowly; the average growth rate is 3.5 - 21.5 mm per year. In some areas colonies build dense settlements.

Morsko stabalce, žuta rožnjača Vrsta koralja, gorgonije mekog skeleta. Polipi ovoga koralja grade kolonije u obliku razgranatog stabla lepezastog oblika. Stablo je žute boje. Unutarnji dio mu je rožnat, a na površini se nalazi sluzava ovojnica sa malim bijelo-žutim polipima. Kolonija može narasti i do promjera od 50 cm. Nalazi se na kamenim zidovima, na mjestima gdje su jače morske struje na dubinama od 10 do 150 m. Hrani se planktonom koji mu donosi morska struja. Kolonijalni koralj, gradi velike razgranate kolonije koje rastu u jednoj ravnini. Polipi nisu izraženi i uglavnom su smješteni na suprotnim stranama ogranka, u istoj ravnini kao i kolonija. Boja varira od svjetleoker do tople žućkasto narančaste boje. Boja nije proizvod sklerita već živućeg tkiva, pa suhe i konzervirane jedinke gube boju. Kolonija raste sporo, prosječna stopa rasta je 3,5 – 21,5 mm godišnje. Na pojedinim područjima kolonije grade gusta naselja.
