There is so much to say about the octopus, that we can't possibly cover it all here.  But I'll try and get to the most interesting facts.  Like the most obvious one: An octopus has eight arms called tentacles.  Each tentacle has 240 suctions cups on it.  Each one of those suction cups has 'taste sensors' that help to identify food. Also, an octopus can change colors.  They usually do this to hide from their enemies.  Sometimes an octopus can be injured by another animal.  If it loses an arm, another one will grow back!  This is called regeneration. Remember when Otto carried Johnny and Joey around, and he used his jet propulsion?  Well, real octopuses are able to reach speeds of 25 miles per hour when they do that! Octopuses are very intelligent.  Scientists have studied them in laboratories, and the octopuses can figure out mazes and even puzzles!
