Frosch Dwarf clawed frogs (Hymenochirus sp.) are aquatic amphibians, i.e. they spend their entire lives in water. However, this doesn't mean that they breathe through gills. Like fully-grown amphibians, they breathe with lungs and partly with their skin, and therefore they have to surface regularly for air. Dwarf clawed frogs are from Africa. They are appr. 3 cm in size, and have a lifespan of about 5 years. They feed on sludgeworms (Tubifex tubifex), and red and wihte mosquito larvae (Chironomus plumosus) which are swallowed and eaten whole.

The Webcam utilizes the JMF (Java Media Framework) library which, in turn facilitates access from Java to video and audio media. The various changes in the images can be displayed by the high-capacity classes of AWT (Abstract Window Toolkit).
