Octopuses Quiz – Clever Creatures With Eight Arms

Octopuses are cephalopods, relatives of squid and cuttlefish, with eight arms, soft bodies and no shell. There are about 300 species, living from tide pools to the deep sea, and they are among the most intelligent invertebrates.

Octopuses have three hearts, blue blood and arms full of neurons that can taste and touch. They change color and texture in an instant to hide or signal, squirt ink to escape and squeeze through any gap larger than their beak.

Octopuses solve puzzles, use tools and escape tanks, as Inky did in New Zealand. Most live only a year or two, and females guard their eggs until they hatch. Their intelligence has led some countries to recognize them as sentient beings.
