Yay, Animals!
Invertebrates
 Animals
that do not have an internal
skeleton


Some don’t have any kind of skeleton
Some have an exoskeleton (e.g. insects)
A
hard outer shell
1. Sponges
 Animals
with bodies full of pores and
channels that allow water to flow through
them
 They filter-feed
 Example: sea sponge
Sponges
2. Worms
 Animals
with long tube-like bodies
(without bones) and no limbs
 Examples:
flatworms, roundworms
Worms
Mollusks
 Can
take on a number of different forms
 All mollusks have a mantle that is used for
breathing and excretion
 Examples:
snails, sea slugs, octopus, clams
Mollusks
Cnidarians
 Invertebrates
that are characterised by
having cnidocytes (explosive harpoon-like
cell)
 Examples:
jellyfish,
sea anemone, corals
Cnidarians
Echinoderms
 Only
live in marine environments
 Radially symmetrical (usually in multiples
of 5-points)
 Examples:
urchins
starfish, sand dollars, sea…
Echinoderms
Arthropods
 Have
an exoskeleton made of chitin and
segmented legs
 Examples:
spiders, insects, crustaceans
Arthropods
Vertebrates
 Animals
that have an internal skeleton
Vertebrates
 Some



vertebrates are warm-blooded
This means that they can control their body
temperature internally
Ex: mammals,
birds
Vertebrates
 Some




vertebrates are cold-blooded
This means that they cannot control their
body temperature internally
They depend on the temperature of the
environment
Ex: reptiles,
amphibians
1. Fish
 They
have smooth or scaly skin
 Live in the water (have gills to breathe)
 Most are cold-blooded, some sharks are
partially warm-blooded
 Examples:
sharks, eels, seahorse, goldfish
Fish
2. Birds
 They
lay eggs (oviparous)
 They have feathers
 They are exclusively terrestrial
 Warm-blooded
 Examples:
cardinal, stork, penguin
Birds
3. Amphibians
 They
lay eggs (oviparous)
 They have smooth skin (except toads)
 They are both aquatic and terrestrial
 Cold-blooded
 Examples:
frogs, toads, newts
Amphibians
4. Reptiles
 They
lay eggs (oviparous) or produce
eggs that hatch in the female’s body
(ovoviviparous)
 They have scales or a shell
 They can be aquatic or terrestrial
 Cold-blooded
 Examples:
turtles, crocodiles, iguanas
Reptiles
5. Mammals
 Most
give birth to well-developed young
(viviparous) except platypus and echidna
 They have fur
 Can be terrestrial or aquatic
 Warm-blooded
 Examples:
platypus, koala, whales, tiger
Mammals
Taxonomic Tree
You need to know how to
interpret a taxonomic tree!

crustaceans part of
the same phylum?
Yes!

closely related to
frogs than to
snakes?
No!
Are sharks and rays
part of class
Agnatha?
No!
Are birds, sharks and
snakes all part of the
same phylum?
Yes!
