  1. Pollination, Crypsis, Aposematic Coloration, and Mimicry 2-22-05

  2. pollination To transfer pollen from an anther to a stigma stigma anther

  3. Orchid bees are both beautiful and good pollinators.

  4. Aposematic coloration conspicuous coloration or markings of an animal serving to warn off predators

  5. Chinese Red-bellied Newt

  6. Chinese Red-bellied Newt If an animal has a dull back and bright undersides, the Unken Reflex may be used. They flash the bright colors, and frighten the predator.

  7. Crypsis Camouflage; blending in with surroundings

  8. Killdeer on nest

  9. The Fer-de-Lance relies on crypsis.

  10. VALUE OF COUNTERSHADING • Many aquatic/marine animals are dark on top and light on the bottom. This is so predators approaching from the top see a dark back against a dark background, and predators from below see a light venter against a light sky.

  11. mimicry the resemblance of an animal species to another species or to natural objects; provides concealment and protection from predators

  12. TYPES OF MIMICRY • Batesian mimicry: The model is poisonous/venomous, and the mimic is harmless. • Müllerian mimicry: The model is poisonous/venomous, and the mimic is, too.

  13. The mimic - Milk snake - non-venomous The model - Coral snake - venomous BATESIAN MIMICRY

  14. MORE NON-VENOMOUS BATESIAN MIMICS

  15. ANOTHER BATESIAN MIMIC.

  16. Mimicry is favored by selection and passed on to future generations (evolution)
