I've been doing a lot of research for my selkie characters and I really wanted to incorporate seal behavior into their society. (Selkies are mythical creatures that are mostly seals but they are able to take off their seal skin and turn into a human.) My research on selkie myths mostly came up with similar stories such as "selkie female has her seal skin stolen by a human man and is forced to marry him until years later she finds her skin and returns to the ocean". So I am trying to use seal information to fill in the blanks.
I am going to base them off of harbor seals because I couldn't find any information about which specific seal they can turn into and a harbor seal would be best for my story. Does anyone have any info about general harbor seal behavior, such as personalities or family group structure? Also any ideas about how to incorporate them into a human-like culture. In the story my selkie character is separated from her community and has to live with humans so any ideas about difference in culture and culture shock would be great too. For example I've read that seals only see in black and white so maybe she is very confused with humans' use of color in pretty much everything and doesn't understand the difference between the traffic light colors. Any info or ideas will help!
P.S. I'm new to this site and forums in general so I'm sorry if I did anything wrong :)
