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.

Chromosera xanthochroa is a waxcap mushroom in the family Hygrophoraceae, associated with old, unimproved grasslands in Europe. Like other members of the genus Chromosera and the broader waxcap community, it is considered an indicator of ecologically ancient grassland that has escaped agricultural intensification. The specific epithet xanthochroa refers to yellow or golden coloration, which is a feature of this species' fruiting bodies. Waxcap species are mycorrhizal or saprotrophic fungi that develop slowly over years to decades in stable grassland soils undisturbed by plowing, reseeding, or fertilizer application. The presence of rich waxcap communities — including multiple Chromosera, Cuphophyllus, Hygrocybe, and Camarophyllopsis species — is internationally recognized as a signal of extraordinary grassland biodiversity value. Countries such as Wales, Ireland, Norway, Sweden, and Estonia hold globally significant concentrations of waxcap grasslands. Chromosera xanthochroa faces pressures from habitat loss driven by agricultural intensification, development, and succession of grassland to scrub and woodland following cessation of traditional grazing. Conservation of waxcap grassland sites requires continuation of low-intensity pastoral management.
