Det er vi enige om, Ole. Min første tanke var da også, at det lignede en Goniopora. Men jeg forkastede det pga formen.ole kekkonen skrev:det Ligner de har Större koralitteR
Jeg kiggede lige efter, hvordan det hænger sammen.ole kekkonen skrev:Ja Erik jeg lavet det om fordi jeg Syntes goniopora var ligesaa godt Bud.
Cyphastrea er det Ikke en favia Art?
Selv med bedre billeder vil jeg Ikke Vide hvad man skal kigge efter?det,er Ikke NOK man Finder et billed der Ligner paa nettet.The Coral Finder lists Echinophyllia in one key group with Echinopora, Oxypora, and Mycedium being possible candidates for confusion.
Og Hvad er costae SAACostae run down the outer edge of the corallite walls feeding into the colony surface which is covered in beaded spinules. Close examination is needed to see these structures in the field; a cursory glance is not sufficient!
Og hvad er septa SAA??Where the septa cross the corallite wall they become costae (singular is costa). The costae run between corallites or out towards the edge of the colony. The costae are often distinctive and may be used to differentiate between genera
Og hvad er SAA coenosteumSepta are vertical skeletal elements inside the corallite wall, and are contiguous with costae when they cross over the wall. Costae may run across the coenosteum between corallites and join with the septa of the next corallite
Er jeg den eneste der Ikke fatter en brik af det?In corals, the coenosteum is the stony skeletal material secreted by the coenosarc, the layer of living material lying between the corallites (the stony cups in which the polyps sit). The coenosteum is composed of aragonite, a crystalline form of calcium carbonate, and is generally a spongy, porous material. Sometimes the coenosteum has ornamentation such as ridges and beads, visible as raised areas of the coenosarc. The coenosteum and corallites together are known as the corallum.[1][2][3]
http://www.coralhub.info/terms/corallite-arrangement/" onclick="window.open(this.href);return false;It is important to understand when looking at a coral colony that specific characteristics may not be repeated across the whole colony surface; make sure you scan the entire colony and then concentrate your efforts on the mid flanks of the coral. Why? Because often at the edges of the colony or on the apex, the corallites are affected by stressors such as competition from neighbouring corals, or exposure to high light levels. These stressors can modify corallite appearance, making identification of predominant characteristics difficult.
Det er svært stof, Ole, helt enig.ole kekkonen skrev:

Hvis du ikke fatter en brik, tror du så ikke vi andre er faldet af for lang tid sidenole kekkonen skrev:http://www.coralhub.info/cf/a-z/echinophyllia/
