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.

Rufous-tailed Hummingbird

One of the most common hummingbirds in Central America and northwestern South America, rufous-tailed hummingbirds are medium-sized with green upper parts and a diagnostic bright rufous-orange tail. Found from Mexico to Ecuador and Trinidad in a wide range of habitats including forest edges, gardens, plantations, and secondary growth from sea level to 2,100 meters. Aggressive territory defenders at feeders and flowering plants, they are frequently seen in gardens across their range. Listed as Least Concern.
