Lesson 1
An animal with a backbone
Vertebrate
Thick, hard outer coverings that support and protect animal's bodies
exoskeleton
An animal that has a notocord, a nerve cord, a tail, and structures called pharyngeal pouches in some point of it's life
notocord
What type of arthropods has one or two pairs of wings?
Insect
Amphibian
An animal that does not have a backbone
Invertebrate
A structure, such as an arm or a leg, that extends from the central part of the body
appendage
A flexible, rod-shaped structure that supports the backbone of a developing chordate
Notocord
What type of symmetry does an annelid have?
Bilateral
What vertebrate has waterproof skin and is covered in scales?
Reptiles
This type of symmetry divides an animal into two parts that are nearly mirror images of each other anywhere through its central axis
Radial Symmetry
Name 3 types of invertebrates we learned in class
-Sponges, cnidarians, flatworms, roundworms, mollusks, annelids, arthropods, echinoderms
Give two characteristics unique to mammals
-have hair or fur
-have mammary glands
-Complex nervous system
What phylum does a is a jellyfish, sea anemones, and hydras in?
Cnidaria
Mammals
This type of symmetry can be divided vertically into two parts that are nearly mirror images of each other
Bilateral symmetry
What are the three types of Arthropods we learned in class?
Insects, Arachnids, and crustaceans
What makes an amphibians development in life unique?
Metamorphosis- changes bodies as they grow into adulthood
What phylum is a snail under?
Mollusk
What are the five major groups of vertebrates we learned in class?
-Reptile
-Amphibian
-bird
-mammal
-fish
This type of symmetry cannot be divided into any two parts
Asymmetry
Give 2 examples of an echinoderm
Sea star, sea urchin, sea cucumber
What are the two important characteristics of fish?
Gills, paired fins
What are the two types of invertebral chordates?
What are the three groups of fish we learned about in class?
-Jawless fish
-Cartilage fish
-Bony fish
