How do animals change color?

the science of chromatophores

Animals like cuttlefish and chameleons are able to quickly change color in-order to blend in with their surroundings. They can do this due to a special type of cell called a chromatophore. Chromatophores work by moving vesicles that contain different color pigments into different forms by contracting and expanding them, so a different color comes to the “surface” when moved, giving the animal a different color. This can either be controlled by the animals nerves or happen hormonally.

 The Pea Aphid (Acyrthosiphon pisum) life cycle:

During the summer months, asexual females give live birth to clonal offspring (see photo). These offspring undergo 4 molts during larval development to become (A) unwinged or (B) winged asexually reproducing adults. Winged individuals are  induced by crowding or stress during either prenatal or early larval stages; they are more able to disperse to colonize a new plant. After repeated cycles of asexual reproduction with generation time of about 10 days, shorter autumn day lengths trigger the production of (C) unwinged sexual females and (D) males, which can be winged or unwinged in pea aphids, depending on genotype.After mating, sexual females deposit (E) overwintering eggs, which hatch in the spring to produce (F) wingless, asexual foundress females. In some populations, especially in locations without a cold winter, the sexual and egg-producing portions of the life cycle are eliminated, leading to continuous cycles of asexual reproduction.

HAPPY NEW YEAR!

I hope you all had a fantastic 2012 and a wonderful New Year’s Eve.  Words fail to summarize how transformative this past year has been for me personally; I’m simply awed by it.  One of those “I never would have imagined” moments.  Not that I want to really get into the nitty gritty, but at the very least I hope my friends and family know how incredibly grateful I am for their love and support and encouragement.  And for you, too, followers: without your interest surely none of this would have happened— like, my grad school decision, the success of this blog, and certainly not the Brain Scoop (26,500 SUBSCRIBERS. ON THREE VIDEOS.)  I am forever in your debt. 

OKAY.  I made it back to Missoula last night and I hope to get into the museum sometime tomorrow.  For the record,  chrisperriman correctly identified the Freak of the Week from December 21st as being the tarsal (feet) bones of a penguin.  More on that soon!  The picture above of a tasier is one of the lantern slides I found a few weeks ago.  I think it does an adequate job of detailing how excited I am for the coming months.
