LSUMNS bayou activity

  1. 1. QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. Life in the Bayou Understanding the frog life cycle and adaptations of bayou animals
  2. 2. Activity 1: Frog Life Cycle QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture.
  3. 3. Activity extension- Frog Malformations Vocabulary: Metamorphosis- A major change in the body appearance and structures as an animal grows. It is a rapid, dramatic change in form. Bio-Indicators- A living creature that can be used to tell you something about the area it lives in. It can be positive or negative. Malformation- Primary errors that occur during morphogenesis that disrupts the formation of a normally formed organ or body part during the early stages of development.
  4. 4. Examples of malformations observed in Leopard frogs 1) missing leg, 2) extra toe, and 3) extra foot.
  5. 5. Activity 2: Bayou Camouflage Vocabulary: Habitat- The enivonment in which an organism lives Bayou- A swampy, slow moving offshot of a lake or river Adaptation- A body part or behavoir that helps a plant or animal survive Camouflage- Protective coloring that helps an animal hide from predator and prey.
  6. 6. Factors that influence camouflage • Develops differently depending on physiology and behavoir of animal (for example, an animal with scales is different than an animal with fur) • Environment is most important factor determining what camouflage looks like. Simplest techinique is to match the “background” of its surroundings. • An animal will not develop camouflage that does not need it to survive.
  7. 7. Color! • Color to match environment • Change color to better match their backgrounds as they move location, or light and temperature fluctuations. • Elements of disquise – Countershading- the coloration of the upper parts is darker than its underside, distorts shadow on ground – Patterns or designs (i.e. moths) – Mimicry- to take on appearance of another object or animal, mimicking its behavoir (i.e.; walking stick, Scarlet king snake)

Non-venomous mimics venomous to avoid predators. Remember- “Red touch yellow, kill a fellow; Red touch black friend of Jack” Scarlet king snake- non-venomous Coral snake- venomous
