Octopuses have four pairs of arms and there are over 300 different species of them.
Some are small, some can reach the arm span of more than 14 feet (4.3 meters) and then, we also have one specie named Octopus Wolfi – also known as the world’s smallest octopus.
Octopus Wolfi was discovered and officially classified one hundred years ago, in 1913. These tiny octopuses measure only 0.6 inches (1.5 cm) in length and weight less than 0.035 ounces (1 gram). They are mostly found in the Indo-Pacific region.
