Habitat & Geographic Range

chimpanzee

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 5 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Cameroon, Congo (DRC), Guinea, Tanzania, and Uganda. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

common arm squid

Habitat

Native to Europe and South America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Chile and Norway.

chimpanzee

Humanity's closest living relative, sharing approximately 98.7% of DNA, chimpanzees inhabit tropical forests and savanna woodlands across central and West Africa. Highly intelligent, social primates that use and make tools, display cultural traditions, and communicate with rich vocalizations including the distinctive pant-hoot. Endangered, with populations declining due to deforestation, bushmeat hunting, and disease transmission from humans.

common arm squid

<em>Brachioteuthis riisei</em>, commonly known as the Common Arm Squid, is a cephalopod mollusk in the family Brachioteuthidae. This species is classified as Data Deficient on the IUCN Red List, reflecting significant gaps in knowledge about its population size, ecology, and distribution. Records of this species have been reported from waters off Chile and Norway, suggesting a broad oceanic distribution. Common Arm Squids are typically mesopelagic or bathypelagic organisms, inhabiting the open ocean at considerable depths during the day and often migrating toward shallower waters at night to feed. Like other oceanic squids, they are likely important components of marine food webs, serving as both predators of small fish and invertebrates and as prey for larger marine predators such as cetaceans and seabirds. The Data Deficient listing underscores the need for additional research into the biology, population dynamics, and conservation requirements of this understudied species. Biological traits of this species remain poorly documented in the scientific literature.
