Question 39: Sirens

Siren, in Greek mythology, is a creature half bird and half woman who lured sailors to destruction by the sweetness of her song.

Now.....

This isn't going to be a question per say 

Did anyone else like me see on television that sirens where like the cousins of mermaids ?

I thought mermaids were good 

And Sirens were bad

They looked the same 

But one sang to kill and the other sang because they liked it 

Question : Why didn't the sirens look like half bird and half woman ?

Like what could possibly be the reason ?

Is it because it was to scary for the kids ?

I don't get it.

I feel like i'm missing a piece here to complete the puzzle 

I wonder if they weren't informed properly ?

I dont know ¯\_(ツ)_/¯¯\_(ツ)_/¯
