Reptiles By: Chris Kan & Raymond Nguyen. Introduction Ectothermic vertebrates with lungs and scaly skin (waterproof). Reptiles are divided into four orders:

VERTEBRATES Body parts and Characteristics. §A vertebrate is any creature that has a spinal column. A spinal column is the large bone structure that runs.

Vertebrates Fishes  All fishes are ectotherms.  Ectotherms- animals with body temperatures dependent upon the temperature of their surroundings. 

Animals Vertebrates.

AMPHIBIANS AND REPTILES SOME ARE SLIMY…SOME ARE NOT!

Chapter 3. Phylum Chordata At some point of their lives, all have a: - notochord - hollow nerve cord - pharyngeal pouches - tail.

Class Amphibia First chordates/vertebrates on land About 375mya Evolved from Dipnoian ancestors Swim AND walk sinusoidally Not totally adapted for life.

Vertebrates. Which of these is most closely related to you?

26.2 Reptiles Reptiles are a diverse group. Reptiles share several characteristics. –ectotherms –covered with dry scales –reproduce by laying or retaining.

Chordates. ◊What is a chordate? 1. Has either a backbone or a notochord (vertebrate) 2. Can either be an ectotherm or an endotherm ◊What is a chordate?

Vertebrates. Animals with backbones Brains encased in a skull Closed circulatory systems Veins and arteries to transport blood.
