The number of feet varies: the common octopus has eight legs, also known as octopus; A squid has 10 legs of varying lengths.
The inner shell is different: the inner shell of the octopus has retreated after evolution. Without the inner shell, the octopus will be softer. The inner shell of squid is relatively developed and calcareous.
The attack methods are different: octopuses usually use ink to attack the opponent to help them escape or forage. If the octopus’s feet are caught by the opponent, the octopus will automatically shorten its feet and run away. Squid mainly use “inkjet” as a weapon to escape or catch food.
IQ is different: octopus IQ is higher than the squid, there are “conceptual thinking”, can solve some problems independently. However, the squid brain is not developed, do things completely by feeling.
