What is an invertebrate? An invertebrate is an animal that doesn’t have
a backbone.
What is a vertebrate? A vertebrate is an animal with a backbone.
A crayfish is an invertebrate.
Molting is the shedding or casting off of an outer layer or covering and
the formation of its replacement. It includes the shedding and
replacement of horns, hair, skin, and feathers.
Two animals that “molt” are: Crayfish, horseshoe crabs, and birds shed
periodically part or all of a coat or an outer covering.
How does an aardvark’s body design help it to obtain food?
An Aardvark can take up an astonishing number of insects with its long,
sticky tongue. Its claws enable it to dig through the extremely hard crust
of a termite or ant mound quickly, avoiding the dust by sealing the
nostrils.
Sometimes the aardvark will press its snout against an opening in a
mound and suck up the termites. Aardvarks, with their keen sense of
smell, also hunt for the long columns of termites that move outside the
mounds at night.
An instinctive behavior (sometimes called innate behavior) is a
behavior that a living thing does naturally without having to learn it. For
example, migrating birds use instinctive behavior to know when to begin
their migration and the route that they should follow.
A learned behavior comes from watching other animals and from life
experiences. By watching their mother, baby ducks learn how to avoid
danger and to know what is good to eat. This is an example of learned
behavior.
The Animalia kingdom is the largest kingdom with approximately 9-10
million species.
Down feathers keeps a bird warm.
Archaebacteria are found in extreme environments such as hot acidic
water (sulfur springs) and concentrated salt water (Dead Sea).
You will be required to name at least three major characteristics of fish,
amphibians, reptiles, birds and mammals.
Fish: “breathe” through gills, swim, lay eggs in
water, most are covered in scales and have fins,
cold-blooded.
Amphibians: use gills when young and lungs as
adults, lay eggs in water, adults have smooth
moist skin, cold-blooded.
Reptiles: lay leathery eggs on land, breath with
lungs, cold-blooded.
Birds: have feathers, lay hard-shelled eggs, most
fly, warm-blooded.
Mammals: have hair, feed milk to their young,
young born live.
