General Fun Facts
What is an octopus?
An octopus (pl.: octopuses or octopodes) is a soft-bodied, eight-limbed mollusk of the order Octopoda.
Octopuses are highly intelligent with complex nervous systems and excellent vision. Their bodies are extremely flexible, allowing them to squeeze through tight spaces.
Camouflage and Color Change
Octopuses use camouflage for both hunting and defense. Specialized skin cells allow them to change color, opacity, and texture to blend in with their surroundings.
- Chromatophores - Contain yellow, orange, red, brown, or black pigments.
- Iridophores - Reflective cells that create a shimmering effect.
- Leucophores - White cells that enhance brightness.
