Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Kariarchaeum pelagius is a member of the DPANN archaea group, representing ultra-small, genomically streamlined organisms found in pelagic marine environments. Like other DPANN archaea, it likely relies on metabolic partnerships with other microorganisms due to its reduced biosynthetic capabilities. Its discovery in open ocean waters extended knowledge of DPANN archaeal diversity beyond sediment and acidic environments.
