They construct a foam nest on a tree branch above a still water source. Eventually the foam liquefies when the eggs are ready to hatch.

Not all frogs survive to make the nest. The Akamata is the most common snake on the Okinawan Islands.  It feeds on venomous habu snakes, baby sea turtles, lizards and frogs.

Underwater Macro Photography with an Ikelite housing

I have always enjoyed shooting macro photography ever since I purchased my first camera. Underwater Macro photography is challenging due to currents, buoyancy control and back-scatter in the water. Below are a few underwater images photographed using the Canon 70D with a Canon EF 100 mm f/2.8 USM macro lens. The Camera and lens are enclosed in an Ikelite underwater housing. I am currently using one Ikelite DS-160 strobe along with one Ikelite DS-200 underwater.
