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.

Weihnachtsinselkauz

The Christmas Island boobook (Ninox natalis) is a small owl in the family Strigidae, endemic to Christmas Island, an Australian territory located in the Indian Ocean approximately 360 kilometers south of Java, Indonesia. It is one of a suite of highly distinctive endemic vertebrates found only on Christmas Island, reflecting the island's long isolation from mainland Australia and Southeast Asia. The species belongs to the boobook owl group, which is distributed across Australasia and the broader Indo-Pacific region. As a small predatory owl, the Christmas Island boobook feeds primarily on insects and small vertebrates, hunting at night in the dense tropical forest that covers much of the island. The remaining rainforest on Christmas Island provides critical habitat for this species. Conservation concerns for the Christmas Island boobook include invasive species, particularly the invasive yellow crazy ant (Anoplolepis gracilipes), which has devastated seabird colonies and dramatically altered forest structure and invertebrate communities on the island. Habitat degradation from phosphate mining activities has also affected parts of the island. The species has a small total population restricted entirely to Christmas Island and warrants ongoing monitoring and targeted conservation management.
