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.

Chitinophaga rupis is a member of the genus Chitinophaga within the family Chitinophagaceae, a lineage of Gram-negative, gliding bacteria in the phylum Bacteroidota. Species of Chitinophaga are ecologically important soil inhabitants defined by their capacity to enzymatically hydrolyse chitin, the second most abundant biopolymer on Earth. The name rupis, derived from Latin for rock or cliff, reflects the substrate from which this species was originally isolated. Like congeners, C. rupis possesses genes encoding chitinase enzymes that break down chitin from fungal walls and arthropod cuticle, releasing nitrogen and carbon into the soil environment and contributing to decomposition and nutrient cycling processes essential to terrestrial ecosystem function. The genus typically exhibits gliding motility on solid substrates, does not form spores, and is strictly aerobic under laboratory conditions. Members are widespread in soils globally, though individual species often show geographic or substrate-specific distribution patterns linked to their isolation source. Chitinophaga rupis is not assessed by the IUCN — as a bacterium it falls outside the scope of wildlife conservation listings. However, understanding the diversity and function of such soil bacteria is increasingly recognised as important for sustainable agriculture and ecosystem management, given their roles in decomposition, nutrient cycling, and suppression of soil-borne fungal pathogens.
