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.

Navicula digitoradiata is a pennate freshwater diatom with a lanceolate outline and finger-like radiating striae extending from a central nodule. It inhabits epipelic benthic zones in rivers, lakes, and brackish environments across temperate and subtropical regions. This photosynthetic diatom contributes to sediment surface biofilm communities.
