Strange animal tales focus on shock value.
Parents need to know that, overall, this docuseries emphasizes shock value over education -- while there are some scattered opportunities for families to learn about animal behavior and science, they're usually overshadowed by the greater factor of curiosity. The amount of over-the-top/iffy content varies by episode, but it's safe to say that sensitive young viewers might be disturbed by scenes of mutant animals (a cyclopic piglet and a dog with no front legs, for instance) or stories of animals eating humans.
