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.

Nitrosopelagicus brevis is a small, aerobic ammonia-oxidizing thaumarchaeon belonging to the abundant marine archaeal group Nitrososphaeria. It inhabits the open ocean, particularly the nutrient-poor photic zone of tropical and subtropical oceanic gyres. This chemolithoautotrophic organism oxidizes ammonia to nitrite and plays a fundamental role in marine nitrogen cycling.
