Invert Phylums
Vert Classes
Inverts vs. Verts
Mystery Classification
Randomness
100

Animals in this phylum, like jellyfish and sea anemones, have stinging cells called nematocysts to catch their prey.

Cnidaria

100

These vertebrates are endothermic (warm-blooded), have feathers, and possess hollow bones that help most of them fly.

Aves (Birds)

100

Roughly this percentage of all animal species on Earth are invertebrates, making vertebrates a surprisingly small minority.

95-97%

100

I have a shell, tentacles, and a beak. I can change color instantly to hide from predators or hunt crabs. Even though I am highly intelligent, I have no bones.

Octopus

100

This term describes animals that cannot regulate their own body temperature internally and must rely on their environment to warm up or cool down.

Ectothermic

200

This is the largest phylum in the animal kingdom, containing creatures with jointed legs and an exoskeleton, such as insects and spiders.

Arthopoda

200

This class of vertebrates is known for having hair or fur and producing milk to feed their young.

Mammalia

200

While vertebrates support their bodies with an internal skeleton, many invertebrates rely on this hard, outer covering for protection.

Exoskeleton

200

I live in the ocean, I am shaped like a fish, and I can swim incredibly fast. However, I breathe air through a blowhole and nurse my calves with milk.

Dolphin/whale/porpoise

200

Spiders and scorpions are not insects; they belong to this specific class of arthropods because they have eight legs and two body segments.

Arachnids

300

Snails, clams, and octopuses belong to this phylum, known for having soft bodies that are often protected by a hard shell.

Mollusca

300

Members of this vertebrate class are ectothermic (cold-blooded), have scales, and lay leathery eggs on land.

Reptilia

300

Vertebrates all belong to this single phylum, while invertebrates are spread across dozens of different phyla.

Chordata

300

I lay eggs, I have a beak, and I am covered in fur. I live in Australia and use webbed feet to swim.

Platypus

300

This is the only species of mammal on Earth that is capable of true, sustained flight.

Bat

400

Earthworms and leeches belong to this phylum, which is characterized by having segmented bodies.

Annelida

400

Leading a "double life," these vertebrates start their lives in water breathing with gills and undergo metamorphosis to live on land as adults.

Amphibians

400

Because they lack a bony internal skeleton to support heavy weight against gravity, terrestrial (land) invertebrates are generally limited in this physical trait.

Size- much smaller

400

I live attached to a coral reef, I pump water through my body to filter out food particles, and I have no tissues, organs, or body symmetry.

Sea Sponge

400

This type of specialized camouflage allows certain invertebrates, like the cuttlefish or walking stick insect, to blend in perfectly with their surroundings to hide from predators.

Mimicry

500

Meaning "spiny skin," this marine phylum includes sea stars and sea urchins, which move using a unique water vascular system.

Echinodermata

500

Sharks and rays belong to a specific class of fish distinguished by having skeletons made of this flexible material instead of bone.

Cartilage

500

This flexible, rod-like structure is found in the embryos of all chordates and develops into the backbone or spinal column in most vertebrates.

Dorsal notochord

500

I have scales and I lay eggs, but I am warm-blooded (endothermic). I cannot fly, so I spend my time running incredibly fast across the African savanna.

Ostrich

500

This primitive, jawless vertebrate is a parasite that uses its suction-cup mouth filled with rows of horn-like teeth to attach to other fish and feed on their blood.
