Just a little quick thing about some cetacean people. ;p
Unlike the guys wich are clearly anthros, I'm not sure how to define exactly these "semi-anthro-mermaid" girls in general, I mean they're not really feral, hence their fin-thumbs, clothes, boobs, etc... ;p also I just realised I didn't really made males version yet. ^^;

However, it seems many semi-anthro-mermaid girls have a certain fondness for bipedal males in general... Probably because they're strongs, practicals and can bring lot of useful things and other little gifts from the surface. ;D
