Medieval sirens and mermaids

[Koen G]

An image like this might, maybe, cause confusion for someone not accustomed to mermaid imagery. The tail has got something on it which could be seen as an eye. And the tail slightly extends beyond the middle, like a fish mouth would.
(Also, weirdest way of drawing breasts..)

The fact that the VM nymph clearly has legs remains problematic though.
