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.

Nitzschia intermedia is a pennate diatom in the family Bacillariaceae found in freshwater to slightly brackish habitats, where it inhabits both benthic and planktonic niches. Its elongate frustule with a keeled raphe and fine transapical striae is typical of the large genus Nitzschia. It serves as a bioindicator of moderate organic enrichment and nutrient levels in aquatic monitoring programs.
