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.

Navicula hambergi is a boat-shaped pennate diatom found in freshwater benthic and planktonic habitats. Its symmetrical, lanceolate silica frustule with a central raphe is typical of the large Navicula genus. This species contributes to aquatic primary production and is used in biological monitoring of freshwater quality, as different Navicula species have varying tolerances to pollution.
