Hsieh, S. Tonia. "Three-Dimensional Hindlimb Kinematics of Water Running in the
Plumed Basilisk Lizard (Basiliscus plumifrons)." The Journal of
Experimental Biology (2003): 1-15. Print. -About 2 feet in length (including tail)
-Long, whip-like tail
-Males have crests on their heads and backs to impress the ladies Taxonomy Tropical Rainforests of Central America
- Southern Mexico to Panama
Spend most of time in trees
Never far from body of water - Females dig shallow trench to lay eggs in
- Up to 20 eggs Reproduction Diet Diet:
Small vertebrates Background Protection from predation:
- Can drop from tree to water
- Sprint, upright, about 5 feet/second across surface of water Predators:
- Birds Materials - 30 plumed basilisk lizards (Basiliscus plumifrons)
- 4.6 m-long water track
- Two sychronized, high speed cameras Methods - Varied-ages of animals measured to assess how lizard shape changes with growth
- Runs filmed with two synchronized high-speed cameras Findings - Kinematic variation among individuals primarily related to size differences rather than speed
- Overall kinematics of running differ drastically from kinematics of animals who run across land Big Picture - To run across water, basilisk muscles and tendons serve related, though very different function than those of animals that run across land - Can sprint across surface for 15 feet +
- Excellent swimming skills (for when gravity takes over) -Legs: long, strong hind legs
-Feet: long toes hind feet, fringed with scales that spread when hit on water - Mother leaves eggs
- Hatchlings born with ability to run (on land and water) climb and swim. - All coordinates transformed into 3-dimensions using direct linear transformations
- Ankle and knee flex in early stance missing in aquatic basilisk running (defining feature in terrestrial locomotion)
- Basilisk legs are used only to produce force against water - In water running, basilisk use their muscles and tendons solely as a force producer, with no springing element. Why is this Important Provides more understanding of terrestrial and aquatic locomotion in animals and how appendage usage are different.
