- In coastal engineering, a tetrapod is a four-legged concrete structure used as armour unit on breakwaters.
- A tetrapod's shape is designed to dissipate the force of incoming waves by allowing water to flow around rather than against it, and to reduce displacement by allowing a random distribution of tetrapods to mutually interlock.
- An organism that uses four legs.

Are tetrapods the direct descendants of fish?
Yes, tetrapods are believed to be direct descendants of fish. Around 360 million years ago, some fish evolved to have limbs and eventually transitioned onto land, giving rise to tetrapods.
Which evolutionary innovation was most significant in helping tetrapods move to dry terrestrial environments?
The evolution of limbs with digits was the most significant innovation that helped tetrapods move onto dry terrestrial environments. This adaptation allowed for weight support, better mobility, and the ability to navigate various terrains.
What are vertebrates that have two pairs of limbs known as?
Vertebrates with two pairs of limbs are known as tetrapods.
What are the six bones found in tetrapod legs?
The six bones found in tetrapod legs are the femur, tibia, fibula, tarsals, metatarsals, and phalanges. These bones make up the structure of the leg and are involved in supporting the body weight, providing leverage for movement, and enabling locomotion.
What does transitional organism mean?
A transitional organism is an organism that exhibits traits of two different evolutionary stages, showing the evolutionary link between two related species. These organisms can provide valuable insights into how certain traits or features evolved over time. Examples include Archaeopteryx, a transitional species between reptiles and birds, and Tiktaalik, a transitional species between fish and tetrapods.
Are sharks tetrapods?
No, sharks are not tetrapods. Tetrapods are a group of vertebrates that includes amphibians, reptiles, birds, and mammals, characterized by having four limbs. Sharks, being cartilaginous fish, belong to the class Chondrichthyes and have fins instead of limbs. Thus, they are classified as fish and not tetrapods.
What is an innovation associated with amphibians?
They are tetrapods.
