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.

Red Avadavat

They inhabit tall grasslands, reeds, and scrub near water from Pakistan and India east to Indonesia. Popular cage birds across Asia and now established as introduced populations in parts of Europe, Japan, and the Caribbean. They live in flocks and produce quiet, musical calls.
