Range

Distributed across Belgium, Denmark, Norway, and Sweden.

African elephant

아프리카코끼리(Loxodonta africana)는 지구상에서 가장 큰 육상 동물로, 최대 7,000 kg에 달하며 사하라 이남 아프리카의 사바나, 삼림, 습지에 서식한다. 뛰어난 지능을 가지며, 모계를 중심으로 한 복잡한 사회 구조를 이루고 초저주파음, 울음소리, 촉각을 통해 의사소통한다. 나무를 쓰러뜨리고 물웅덩이를 파며 씨앗을 산포하는 생태계 엔지니어로, 현재 취약(VU) 종으로 분류되며 상아 밀렵과 서식지 손실로 인해 개체수가 감소하고 있다.

Cleanser crab

The Cleanser Crab is a common name used for various species of commensal or cleaner crabs that establish mutualistic cleaning relationships with larger marine animals such as fish, sea turtles, and invertebrates. These crabs remove parasites, dead tissue, and debris from the host organism's body surface, gills, and mouth, benefiting both the cleaner and its host. Cleaning behavior has evolved independently across multiple crab lineages, particularly among small xanthid, pinnotherid, and porcellanid crabs that live in close association with host organisms on coral reefs and rocky intertidal zones. Cleaner crabs are often found in tropical and subtropical marine environments, especially on coral reefs where complex ecological interactions and high biodiversity create numerous opportunities for symbiotic relationships. The physical structure of cleanser crabs typically features specialized mouthparts and chelipeds adapted for precise manipulation of external parasites and necrotic tissue. As with all reef-associated species, populations of cleaner crabs are sensitive to coral reef degradation driven by warming ocean temperatures, ocean acidification, and overfishing. Specific conservation status depends on the species referred to under this common name.
