Octomaid

Octomaids are mermaids with the features of an octopus.

Appearance
Octomaids have the upper body of a human female, and the lower body of an octopus. They generally have long, curly hair and tubular shaped pupils along with spotted skin.

Behavior
Octomaids are the most solitary of all the mermaids. However, unlike mermaids, they aren't socially awkward or easily frightened per say. Instead, they made the decision that being around other people wasn't the "smart" decision to make based on the factors around them, though they're completely prepared to converse with other people if it benefits them.

By nature, octomaids are highly intelligent and have the ability to make an informative and helpful prognosis based on what they already know. Their knowledge can even come off as intimidating by others, especially because they often show off and may even become confrontational when others dare to question their beliefs and predictions.
