Nature doesn’t insist on a single blueprint. Many animals thrive without a centralized brain, relying instead on simple nerve nets, ring-and-radial nerves, or chains of ganglia to sense, move, feed, and reproduce—especially in the sea. Here’s a clear, reader-friendly guide to 14 classic examples....
Coasts and nearshore waters are among Earth’s richest life zones.

Frugivores are animals that obtain much (or most) of their nutrition from fruit. Some species are almost strict fruit eaters, while many are facultative frugivores that eat fruit seasonally or opportunistically within a broader herbivorous or omnivorous diet. Frugivores form mutualistic interactions...
Earth’s biodiversity is astonishing—scientists estimate around 8.7 million species. While some prehistoric reptiles may have had feather-like structures, today only birds truly have feathers.
