Hints for bit-o-critter rounds 9, 10 and 11

I guess I got carried away with making bit-o-critter a little harder after everyone so quickly solved the Chrysaora.  Here's some cryptic hints for the three open rounds noone has guessed at yet:

Round 9 - One more than normal
Round 10 - Men are distinctly uncomfortable around this animal
Round 11 - This group not discovered until 1983

I will post the solutions when I get back to Atlanta tomorrow.
