Common Green Capsid

<em>Lygocoris pabulinus</em>, commonly known as the common green capsid, is a plant bug belonging to the genus Lygocoris within the family Miridae. The species inhabits virtually all terrestrial and freshwater habitats, reflecting a generalist ecological strategy. Its documented range spans Taiwan in Asia, four European countries, and both Canada and the United States in North America. Common green capsid is assessed as Least Concern on the IUCN Red List. This small heteropteran is typically bright green in color and is associated with a wide variety of herbaceous and woody host plants, occasionally reaching pest status in agricultural settings where it damages soft plant tissue. Biological traits of this species remain poorly documented in the scientific literature.

Common Seal

The most widely distributed pinniped, harbor seals inhabit temperate and subarctic coastal waters of both the North Atlantic and North Pacific. Adults reach up to 130 kg and spend roughly equal time at sea hunting fish, squid, and crustaceans and hauling out on beaches or rocks to rest. Their large, expressive eyes are adapted for underwater vision in low light. Harbor seals are a critical food source for orcas, sharks, and polar bears.
