What are the difference between vertebrates and invertebrates?
Vertebrates are animals that have a backbone inside their body. The major groups include fish, amphibians, reptiles, birds and mammals. Invertebrates don’t have a backbone. They either have a soft body, like worms and jellyfish, or a hard outer casing covering their body, like spiders and crabs.

Are sharks invertebrates?
Sharks are classified as vertebrates, meaning they have a backbone. A shark’s backbone is not really made out of bone it is cartilage. Sharks are grouped under the category of fish called cartilaginous fish. Other cartilaginous fish include rays and skates, which are similar to sharks.
Is a fish a vertebrate or invertebrate?
Fish are considered vertebrates (with a backbone), and most fish have scales, fins, and gills. Fish use their gills to breathe, but some types of fish have lungs as well, and can breathe out of water for long periods of time.
Are lobsters invertebrates?
Lobsters, like insects, belong to the invertebrate phylum Arthropoda. Besides lobsters and insects, spiders and snails belong to this group as well.

How many aquatic invertebrates are there?
They form a phylum containing over 10,000 species of animals found exclusively in aquatic (mainly marine) environments. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick.
Is Starfish a fish?
Sea stars, commonly called, “starfish,” are not fish. They do not have gills, scales, or fins. Tube feet also help sea stars hold their prey. Sea stars are related to sand dollars, sea urchins, and sea cucumbers, all of which are echinoderms, meaning that they have five-point radial symmetry.
What are three aquatic examples of vertebrates?
