Fossilised Neidium sp. diatom, SEM
Coloured scanning electron micrograph (SEM) of a fossilised Neidium sp. diatom. Neidium sp. diatoms are known for their valve shapes, which can range from rounded to capitate, rostrate, or protracted ends, depending on the species. Thriving mainly in slightly acidic waters, Neidium, although not abundantly found, plays a crucial role in aquatic ecosystems and is widely distributed. Diatoms contribute significantly to the oxygen in the atmosphere and are a fundamental link in the aquatic food chain. Diatoms are among the most diverse species on earth. Estimates of the number of diatom species range from 20, 000 to 2 million. Scientists are discovering new species every year. Magnification: x1520 when printed 10 centimetres wide.
