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.

Haladaptatus pallidirubidus is a halophilic archaeon in the family Halobacteriaceae producing pale reddish-pink colonies due to carotenoid pigments. Like other members of its genus, it is adapted to moderate-to-high salinity environments and was isolated from saline water sources. Its carotenoids likely provide photoprotection and may contribute to photoactive metabolic pathways.
