Animal inspired submarines

Some submarines inspired by dolphin, shark and turtle.

This last one, also animal inspired. Take a guess what animal it is. :slight_smile:
No looking a filenames please.

A whale maybe?^^
Cool ideas man! :slight_smile:

Yes, it is a whale, but what kind? :slight_smile:

Actually, as they are commishioned work, they are not my ideas. But I have had very limited instructions so all designs are mine.
