Chordata
Important Information:
Lion(Panthera leo): A large tawny-colored cat that lives in prides, found in Africa and northwestern India.
The lions nervous system consists of a Brain, spinal cord, and nerves much like a humans. The only difference between the lions nervous system and the humans is that it has a less developed brain and the nerves are used to sense touch.
Tiger Shark(Galeocerdo cuvieri): An aggressive shark (Galeocerdo cuvieri, family Carcharhinidae) of warm seas, with dark vertical stripes on the body.
The Nervous system of the shark controls its behavior, including its will to attack. The sharks Nervous consist of a simple brain, spinal cord, and a network of nerves.
Crocodile(Crocodylus acutus acutus): A reptile with a long tapering head, occurring from southernmost Florida to Ecuador.This reptiles nervous system consists of a brain, a spinal nerve cord, nerves running from the brain or spinal cord, and sense organs like most of the animals in the Chordata phylum. When reptiles such as the American crocodile are compared with mammals, reptiles have proportionately smaller brains. Like most animals that are higher vertebrate such as the crocodile, have a autonomic nervous system (the part of the nervous system responsible for control of bodily functions not consciously directed, such as breathing
- They include tunicates, lan and vertebrates which include fish, amphibians, reptiles, birds, and mammals.
- Have their skeletons on the inside, a design that allows for growth without the need of molting
- 97% of the living Chordates are vertebrates- animals whose skeletons include a backbone.
- 3 features present in all Chordates include a stiffening rod, hollow nerve structure(dorsal nerve cord), and structures called pharyngeal gill slits, or clefts.
- Chordate's have the most developed brains and complex nervous system compared to the other phylum.
