Arnoux's beaked whale

The Arnoux's beaked whale, Berardius arnuxii, is a species. It is currently assessed as least concern on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

One of the world's most remarkable migratory insects, monarch butterflies undertake multigenerational round-trip migrations of up to 4,800 km between breeding grounds in northern North America and overwintering sites in Mexican mountain forests. Brilliant orange and black wings warn predators of toxicity derived from milkweed plants consumed as caterpillars. Endangered, with overwintering populations having declined by over 80% since the 1990s due to milkweed habitat loss, pesticides, and climate change.
