Common Coontail

<em>Ceratophyllum demersum</em>, commonly known as common coontail or hornwort, is a submerged aquatic plant in the family Ceratophyllaceae. It has an almost cosmopolitan distribution, occurring on every continent except Antarctica in freshwater lakes, ponds, slow-moving rivers, and ditches. Common coontail is rootless, floating freely or loosely anchored in sediment, and forms dense underwater mats that provide important habitat and refuge for fish, invertebrates, and waterfowl. Its whorled, forked leaves are stiff and brittle with toothed margins. The species is well adapted to a wide range of water conditions and can tolerate turbid, nutrient-rich waters where other aquatic plants may struggle. It plays a significant role in aquatic ecosystems by oxygenating water and filtering excess nutrients. The species is assessed as Least Concern by the IUCN. Biological traits of this species remain poorly documented in the scientific literature.

Fly Agaric

A amanita-das-moscas (Amanita muscaria) é um dos fungos mais icônicos e reconhecíveis da Terra, exibindo chapéus vermelhos marcantes com verrugas brancas nos bosques boreais do hemisfério norte. Apesar de sua aparência de conto de fadas, contém potentes compostos psicoativos como muscimol e ácido iboténico, sendo moderadamente tóxico. Forma simbioses micorrízicas essenciais com bétulas, pinheiros e abetos, trocando nutrientes minerais por carbono e desempenhando papéis fundamentais na ciclagem de nutrientes nas florestas boreais.
