Nature Is Weird
Meet real animals, plants, fungi, and microscopic life whose biology looks impossible until you see how it works.
Nature Is Weird starts with an animal, plant, fungus, or microscopic organism that looks as if somebody made it up. The explanation then follows the anatomy, habitat, senses, and behavior that make the strange feature useful.
The channel pays particular attention to details that photographs can mislead us about: where an animal’s eyes really are, what a structure protects, or how a body works in an environment humans rarely see.
