Sexual activity among Squid is addressed in a clinical sense. They address the proper names for a Squids male and female parts - though they avoid using any words you would not want a child to hear. There is no nudity.

There is no violence between people. However, in episode two the main male is attacked and hurt by a Giant Squid - not badly. The only "gore" - if you will - is cutting open the Squid, the eating of other animals, and squid committing acts of cannibalism.

There is no profanity in this show.

There is alcohol, drugs, or smoking in this show.

There are attacks by the Giant Squid in episode 2.
