BLUE RINGED OCTUPUS
The blue ringed octopus is a invertebrate which are are animals that neither possess nor develop a vertebral column and don't necessarily have a skeleton. This type of octopus has no skeletal system; making them so flexible. They have special muscles on their arms and tentacles which are called muscular hydrostat. This means that an octopus doesn't have neither an inner or outer skeletal system which is what allows them to move so freely and without problems. They are able to adapt to places and things very well and are able to move efficiently and without worrying that they will brake a bone or something.
