InvertebrateInvertebrate Animals AnimalsThey do not have a backboneClassification by structure can be
done in several ways.◦ Body Plan (See next Slides)◦ Presence or Absence of a Head, Most
animals have a head. But, some of the simpler animals like sponges do not have a brain or a head.
◦ Food Digestion ( Almost all animals have a gut. A gut is a pouch lined with cells that release powerful enzymes. The enzymes break the food down into very small particles that can be absorbed by the body.
Invertebrate Body PlansInvertebrate Body Plans
Radial Symmetry, Animals with radial symmetry have a body that is organized around the center like spokes on a bicycle wheel.
Invertebrate Body PlansInvertebrate Body Plans
Bilateral Symmetry, Animals with this type of body plan could be split into two resulting in identical halves.
Invertebrate Body PlansInvertebrate Body Plans
Asymmetrical; Animals with this body plan cannot be divided equally into two halves or be the same in any direction.

Invertebrate AnimalsPhyla
Phylum PoriferaPhylum Porifera: Station 1: Station 1
This phylum includes the sponges and are the simplest of all animals. They have no brain, nerves or gut. Most are found in the ocean.
They have pores in their body walls so that water can enter and they can filter feed.

worms. They are very tiny and round. A single rotten apple lying on the ground could contain as many as 100,000 roundworms. They help break down dead animals and plants to build soil. They have a get and a very simple brain. They are parasites (meaning live on and in other things) and can infect humans. Some of the more popular forms are pin worms and hook worms.
These are cylinder (round) shaped worms

Phylum Annelida: Phylum Annelida: Station 5Station 5
These include segmented worms. They have a more advanced nervous system and gut than the more simple invertebrates
Bodies are made of identical repeating segments

Phylum Mollusca: Phylum Mollusca: Station 6Station 6This group includes snails, clams and
squid, oysters and more. They have the most advanced nervous system of all invertebrates. You will get to dissect a squid.

Phylum Chordata (The Phylum Chordata (The Vertebrates)Vertebrates)These animals have a backbone
and skullThere are five main classes of
the Phylum Chordata: Fish, Amphibians, Reptiles, Mammals and Birds.
FishFishHave gills for breathing in waterHave scalesHave fins for moving
◦ There are about 28,100 species of fishes known, they are divided into 4 classes, 59 orders, 490 families and about 4,300 genus groups. The classification system of fish is not unchanging and it will change when we have more knowledge, perhaps from DNA analyses. Class Myxini (Hagfish are eel-shaped, slime-producing, marine fish
occasionally called slime eels) Class Cephalspidomorphi (Lampreys or Early Jawless Fish with an eel like body
form) Class Chondrichthyes (Sharks and Rays or Cartilage Fish) Osteichthyes (Trout, Salmon and etc.)

AmphibiansAmphibiansMost amphibians living today are frogs or
salamanders. They are thin skinned and absorb water
through the skin.Live in water and on land. Frogs, Toads, Salamanders

ReptilesReptilesThese are ancient. They are thick
skinned and cold blooded. This means that they can’t maintain their own body temperature.
They main types of reptiles are crocodiles, alligators, lizards, and snakes.

BirdsBirdsThey have beaks instead of jaws
and teeth. They also have wings and
feathers that adapt them for flight.
