Tiger Salamander Migration Facts

Location/Distance

• The tiger salamander migrates up to 2 miles from pond where they were born.

• They roam throughout the habitat during their lives, especially when they are young.

Mating

• Eggs are fertilized by internal fertilization of the females.

• Oviposition happens in several batches within one breeding season.

• Up to 1300 eggs may be deposited in several batches.

Feeding

• Young: Algae, crustaceans, mosquito larvae

• Adults: Insects and tadpoles
  
  

Migration Cues

• Mediterranean climate's rainy season during December to January is a migration cue.

• Lower average temperature is also a cue for the salamaners.

• Vernal pool habitats in lowlands - pools must be dynamic and well-formed
  
  

Navigational Mechanisms

• Magnetoreception - detect orientation and polarity information from Earth's magnetic fields (magnetic compass)

• Celestial cues - polarized light helps guide the salamanders

• Olfactory cues: vegetation/habitat and pheromones
