Photos of the Giant clam (Tridacna) of the red sea and Fiji and the Pen shell (Pinna bicolor) of Namenalala on Fiji, from the Pacific

Almost several photos were taken on Namenalala/Fiji, some of them also at the Red Sea.
Even near the landing pier there is a lot to see for the diver: an accumulation of Giant Clams (Tridacna), a part of them up to 40 years old, in addition colourful Christmas-Tree Worms and Coral Fish.
The Giant Clams of the species Tridacna are the biggest and fastest growing mussels. The Giant Clam can reach a size of more than one metre and a weight of 300 kilograms. Giant Clams with their beautiful colour markings belong to the highlights of the coral reef. I knew the Pen Shell (Pinna nobilis) from the Mediterranean. I was all the more surprised when I saw a beautiful, heavily incrusted Pen Shell while diving on Fiji. However, this was a Pinna picolor.
While the Pinna nobilis can reach a size of up to 90 centimetres, the two species found on Fiji, Pinna picolor and Atrina vexillum, reach only just under half the size. Another, much smaller Pen Shell of the Fiji region is called Pinna muricata.
