Q&A

Is it more likely that merfolk would evolve with horizontal or vertical tails?

+0
−0

Another mermaid questions I'm afraid!

Fish have tail fins which are vertical, whales have fins which are horizontal. My race of merfolk are:

  • Very active (more likely to be warm blooded)
  • Have gills and lungs so can breath in and out of water
  • Have scaled tails (like a fish) and human-like skin on their top half (although thick to avoid the chill of the water).

Is it more likely that such a race would evolve with a horizontally or vertically orientated tail? What are the advantages of both?
