The subject of our latest AquaNerd Picture of the Week isn’t a particularly rare one, but it certainly is beautiful enough to garner some attention. The coral is of the Trachyphyllia variety, a coral that has a large calcium skeleton that houses a huge amount of flesh. The “fleshyness” of the coral pictured here is a pretty common sight, though the coral can also exhibit an often bizarre looking feeding mode. During its feeding mode, the brain coral puffs up even more and its tentacles come out from under the lobes of skin and the mouth protrudes outward to a certain extent.
