Made of multiple eukaryotic cells and is a consumer

2 things that are true about all animals.

Radial

What type of symmetry do cnidarians have?

Cephalization

This is a concentration of an animal's sensory organs and a brain at one end of the body.

Chordates

Animals that at some point during their lives have a notochord.

Endotherm

An animal, such as a bird, that can regulate its inner body temperature.

Baraminology

This word is made from the Hebrew words meaning "created kind".

It has no backbone.

Why is a lobster not considered a vertebrate?

sponge

Which animal is "pore bearer"?

Segmented worms

These have repeating body divisions that contain the same set of organs.

oyster

Which is not an arthropod? scorpion, oyster, crab, butterfly

chelicerae

A type of mouthpart.

They have skulls, vertebrae(backbones), and endoskeletons.

3 things true of all vertebrates.

jawless fish

What type of fish are Lampreys and hagfish?

Cartilaginous fish

What type of fish are sharks and rays?

Amphibians

The skin of this animal has the ability to exchange oxygen and carbon dioxide.

It has a 4 chambered heart.

What characteristic sets crocodiles and alligators apart from all other reptiles?

They have hair, they have mammary glands, and they produce milk for their young.

3 characteristics of all mammals.

umbilical cord

This attaches the embryo to the placenta in some mammals.

Sexually

How do animals reproduce most of the time?

complete gut

This type of digestive system has 2 openings.

exoskeleton

Some invertebrates have a hard outer covering to support its body.

Invertebrates

95% of the animals of the world are this type of animal.

Marsupial

An animal that raises their young in a pouch.

Sponge

This is an invertebrate without symmetry, cephalization, or guts.

echinoderms

Sea urchins and other marine animals with radial symmetry and spiny skin.

worms

long, soft-bodied animals with bilateral symmetry

crustaceans

arthropods with either 8 or ten legs

insects

the only invertebrates that can fly

cnidarians

jellyfish and coral are an example of these

chelicerates

spiders, scorpions, and other arthropods with 2 body segments and 8 legs

mollusks

invertebrates (except for cephalopods) that rely on hard shells for protection

ectothermic

Snakes often need sunlight to warm their sluggish bodies after a cold night because they are _____________________.

arthropods

Invertebrates with jointed appendages.

molting

Periodic shedding of skin by squamates.

Their supposed common ancestors.

Evolutionary taxonomists classify or reclassify animals on what basis?

Cnidocytes

stinging cells in cnidarians used to capture food

Their endoskeleton is not made of living cells.

Squids have a hard internal structure supporting their body that is often considered an endoskeleton. Why are squids not classified as vertebrates?

Snakes have no legs, lizards do. Snakes do not have ear openings, lizards do. Snakes have immovable eyelids, while lizards are movable.

3 Differences between snakes and lizards.

placental mammals

What type of mammal is a dog and a whale?

marsupials

What type of mammal is a kangaroo and opossum?

monotremes

What type of mammal is a echidna and a platypus?

The Creation Mandate tells us to rule and care for all creatures including the salmon.

Explain according to the Bible, why managing over 200 separate salmon stocks is not a waste of time.

symmetry

One characteristic used to classify animals into various phyla.

bilateral, radial, and asymmetry

3 types of symmetry

Whether the organism has a head at one end (cephalization)

Another characteristic that is used to classify animals.

The presence of a body cavity, and whether the gut is incomplete or complete.

Another characteristic that is used to classify animals.

The presence of a notochord or a backbone

Characteristic that is used to classify animals.

An animals ability to regulate it's own body temperature.

Another characteristic that is used to classify animals.
