Buckelwal

혹등고래는 대형 고래 중 가장 활발한 곡예를 선보이는 종으로, 번식기에 수컷이 부르는 복잡하고 신비로운 노래로 유명합니다. 일부는 몇 시간씩 지속되며 시간이 지남에 따라 진화합니다. 체장 16미터, 체중 30톤에 달하며 포유류 중 가장 긴 이주를 수행합니다. 모든 대양에서 발견되며 크릴과 작은 물고기를 협동 거품그물 먹이 방식으로 포식합니다. 과거 포경으로 크게 감소했던 개체군이 대부분 회복되었습니다.

coat-of-mail chiton

Coat-of-mail chiton (Leptochiton asellus) is a small marine mollusc in the class Polyplacophora, family Leptochitonidae, found in cold waters of the northeastern Atlantic and North Sea, including the coasts of Norway, the United Kingdom, Ireland, France, and the Iberian Peninsula. It lives on rocky subtidal and shallow intertidal substrates, grazing on encrusting algae, diatoms, and organic detritus adhering to rock surfaces. Like all chitons, it has a distinctive dorsal shell composed of eight articulated plates surrounded by a muscular girdle, allowing it to curl into a ball when dislodged—a characteristic that has earned chitons the common name coat-of-mail. Leptochiton asellus is a small species, typically reaching only 10–20 millimetres, and is often found in aggregations beneath stones and boulders. It is assessed as Least Concern by the IUCN, with stable populations across suitable rocky intertidal and subtidal habitats throughout its range. Chitons as a class are ancient molluscs with fossil records extending to the Cambrian period, representing one of the most primitive lineages of shell-bearing invertebrates.
