Back in the water again and also hitting the marine species identification books for a job we are working on. Finally learning the names of the creatures I’ve been staring at or photographing the last couple of decades. The top featured image is a pink anemonefish (Amphiprion perideraion) I encountered last week. Looking back through my old images I can start working out what they are. A tomato clownfish (Amphiprion frenatus) living in a bubble-tip anemone (Entacmaea quadricolor). Hard to tell, but I think this next guy is Amphiprion clarkii, known commonly as Clark’s anemonefish. A false clown anemonefish (Amphiprion ocellaris). This is Nemo’s species. Another pink anemonefish (Amphiprion perideraion) Identifying the anemones is an even greater challenge. Particularly, as at times what looks like an anemone may in fact be a coral. Below is Amplexidiscus fenestrafer that is sometimes called the elephant ear anemone but is more accurately named the giant cup mushroom coral. Much more learning to be done.
At one of the dive locations there was a huge field of anemones with a multitude of clownfish. I wonder if there had once been vast groups of anemones like these on mainland Okinawa, which have since disappeared due to pollution or their removal for aquariums. This colony seems to have done particularly well in the clear, but rough seas off the coast of Yonaguni.
