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.

Halorussus rarus is a halophilic archaeon in the family Halobacteriaceae, isolated from saline lake sediments in China. It is Gram-stain-negative by the standard test, pleomorphic, and requires high sodium chloride concentrations for optimal growth. Its genus, established in 2008, represents one of many specialist lineages adapted to hypersaline terrestrial environments.
