Common cattle grub

<em>Hypoderma lineatum</em>, commonly known as the common cattle grub, is a parasitic fly species with documented occurrences in Japan, Norway, Sweden, and the United States. It typically inhabited terrestrial and freshwater environments, often associated with cattle and other large ungulates on which its larvae develop as subcutaneous parasites. The species is classified as Extinct on the IUCN Red List, indicating that it is no longer known to exist in the wild. Common cattle grub belongs to the genus <em>Hypoderma</em> within the family Oestridae. Adult flies do not feed and are short-lived, while larvae burrow under the skin of host animals, causing a condition known as hypodermosis or warble fly infestation. The decline and extinction of this species has been linked to widespread and highly effective veterinary treatment programs targeting warble fly larvae in cattle, which drastically reduced host populations and ultimately eliminated the species. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature.

jaguar

美洲最大的猫科动物，体重可达100千克，体型粗壮健硕，毛皮具有独特的玫瑰形花纹。分布于墨西哥至南美洲，亚马逊和潘塔纳尔是其主要栖息地。美洲豹是出色的游泳健将和顶级捕食者，在调节猎物种群方面发挥关键作用。由于森林砍伐导致栖息地缩减，被列为近危（NT）物种。
