Komodo Dragon

The Komodo dragon is the largest living lizard. It is found only on a few Indonesian islands.

Surirella biseriata is a large, boat-shaped freshwater diatom with two rows of fibulae forming a distinctive pattern along both sides of the valve. It inhabits benthic zones of clean to moderately enriched freshwater lakes and rivers across temperate regions. This photosynthetic diatom contributes to benthic algal communities and organic matter production.
