The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923?base pairs. The human mitochondrial genome (mitogenome), for example, comprises 16,569 base pairs. Tube anemones (Ceriantharia) are the focus of an article recently published in Scientific Reports describing the findings of a study led by Sérgio Nascimento Stamper (https://bv.fapesp.br/en/pesquisador/171695/sergio-nascimento-stampar/), a [...]

A microscopic aquatic fungus is responsible for the heaviest biodiversity loss ever found to be due to a single pathogen, according to an article published in the journal Science on March 28.

In some cases, they have dwindled to less than 10% of their original distribution, and 91 species are [...]
