Concerning message #16119:

In response to question of color variation in Tritonia diomedea. I have worked with them for 15 years and have noticed significant variations that seem to be correlated with the location that they are found and possibly on their food source. They vary from a peach color, to orange, deep pink. We have speculated that it depends upon which food source they are feeding on. The Tritonia that feed on sea pens (Ptilosarcus) are more orange than the ones that feed on sea whips (Virgularia). Once, I saw some from California that may have been feeding on sea pansies. They were deep pink.
