common pygmy woodlouse

The Common Pygmy Woodlouse, <em>Trichoniscus pusillus</em>, is a small terrestrial isopod crustacean in the family Trichoniscidae, widely distributed across Europe and introduced to North America, with records from Denmark, Norway, Portugal, Sweden, and the United States. It is one of the most abundant and widespread woodlice in temperate regions, typically found in moist, dark microhabitats including under stones, logs, leaf litter, bark, and in soil crevices in gardens, woodlands, and grasslands. <em>Trichoniscus pusillus</em> is a very small species, measuring only a few millimeters in length, with a reddish-brown to pale pink coloration and a smooth, slightly convex body. Unlike many larger woodlice, it does not roll into a ball when disturbed. The species plays an important role in decomposition and nutrient cycling, fragmenting decaying plant material and facilitating microbial breakdown. It is parthenogenetic in many parts of its range, with all-female populations reproducing without males. The species is assessed as Least Concern on the IUCN Red List given its abundance and widespread distribution. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.

giraffe

A girafa (Giraffa camelopardalis) é o animal terrestre mais alto da Terra, podendo atingir 5,5 metros de altura e pesar até 1.750 kg. Seu pescoço alongado, contendo as mesmas sete vértebras cervicais de todos os mamíferos, evoluiu para se alimentar de acácias nas savanas e bosques africanos. Animal social que vive em manadas soltas sem vínculos permanentes, comunica-se por infrassons e linguagem corporal. Vulnerável, com populações em declínio devido à perda de habitat e à caça ilegal.
