What are vertebrate and invertebrate animals?
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.
What are the diversity of animals?
The diverse appearance of animals is mostly superficial; the bewildering variety of known forms, some truly bizarre, can be assorted among a mere half-dozen basic body plans. These plans are established during the embryonic stages of development and limit the size and complexity of the animals.
What is invertebrate diversity?
Invertebrates range from spiders and scorpions to centipedes and millipedes, crustaceans, insects, horseshoe crabs, worms, leeches, earthworms, marine bristle worms, mussels and clams, snails, squid and octopi, sea anemones and corals, among others. …
Why are invertebrates more diverse?
Overall the bank habitat had higher species diversity and richness than the river habitat, therefore, protection of bank habitats would cover the most richness and diversity of invertebrate species.
Why is there so much diversity among invertebrates?
Why is there so much diversity among invertebrates? 95% of animals are invertebrates & all have different adaptions. They keep evolving into new organisms.
What do all animals including vertebrates and invertebrates have in common?

How are invertebrates apart of biodiversity?
Invertebrates comprise the bulk of animal species diversity in all terrestrial habitats, including freshwater, within Otago Conservancy. Kuschel (1990) estimates our beetle fauna at 10 500 species and total insect fauna at 42 000 alone.) As less than 2% of these are introduced, the great majority are native species.
Which has highest species diversity among the invertebrates?
Insects have highest number of species found in nature. The insecta is the largest class of animals. It ! has over 7,00,000 species. The insects are the most successful land invertebrates and the only major competitors with humans for dominance in the world.
