common Atlantic octopus

One of the most studied invertebrates in neuroscience and behavioral biology, common octopuses inhabit rocky reefs and seafloors in tropical and temperate coastal waters globally. Highly intelligent with distributed nervous systems — two-thirds of their 500 million neurons reside in their arms — they demonstrate tool use, problem-solving, and individual personalities. Masters of camouflage, they change skin color and texture in milliseconds. They have three hearts, blue copper-based blood, and extremely short lifespans of 1–2 years.

Speckled Hummingbird

A medium-sized hummingbird with speckled or spotted underparts — unusual among hummingbirds dominated by plain or iridescent plumages — speckled hummingbirds inhabit cloud forest and forest edges in the Andes from Colombia and Venezuela south to Bolivia at elevations of 900–3,000 meters. The spotted underpart pattern provides remarkable camouflage when the bird perches on lichen-covered bark. They forage on nectar and small arthropods and are important pollinators of Andean epiphytes.
