The role of predation is far more complex than researchers have traditionally assumed. Thank you for considering my comments. Trowbridge, C.D. 1994. Thanks Cynthia, I wish we could get more researchers interested in this type of study. It is a very complex set of questions.
Some species appear well camouflaged and others are brightly coloured at least to our eyes.
Many have nasty chemicals and at least on initial contact are avoided by fish. It seems there will be no general or simple rule that covers all species. By the time the predator is experiencing your nasty secretions, your chances of survival are probably quite low. Comment on Predation on sacoglossans by Cynthia Trowbridge. I thought you could add these to the predator list .
