What are the main features of invertebrates?
1.they have basically three body parts i.e: head , thorax and abdomen. 2.they have no lungs. they respire through their skin. 3.they live in colonies . 4.some are harmful for humans like termite, mosquitoes jelly fish and houseflies. 5.they lay eggs and not babies.

An invertebrate doesnt have a backbone. A vertebrate has a backbone.
An invertebrate is an animal that doesn't have a backbone. The fourmain invertebrate groups are arthropods, worms, mollusks andsponges.
None, all are in different groups
Invertebrates are creatures with no backbone. Instead they mighthave an exoskeleton.
The five main invertebrate categories (animals with no backbone) are mollusks, sponges, worms, arthropods, and jellyfish.
1. arthropod 2. mollusk 3. echinoderm 4. idk
Every animal phyla except for Chordata are the main phyla of invertebrates.
The 5 main invertebrates are: . Porifera (Ex: sponges) . Cnidaria (Ex: jellyfish) . Other Bilaterian: Nematoda, Arthropoda, Mollusca, and Annelida . Echinodermata (E…x: sea urchins) . Chordata (Ex: hagfish)
the main features means what is the usual features
This is their defence. lower invertibrates (such as butterflies) only have their bright, posinous colour to scare preitors off. Other higher invertibrates such as scorpians ha…ve clippers to scare preitors off. If something was to have ago at a scorpian, it could fight back; unlike th butterfly. Hope that helps :)
In Zoology or Animal Biology
Higher vertebrates generally have a central nervous system and/or brain, or take the negative of that, sponges are the most primitive multicellular animal phylum, lacking a ne…rvous system; cnidarians (true jellies, coral etc) are next up the ladder and while they have a nervous system lack a true brain; while insects in the next major group up the ladder (protostomes) have a brain, deuterostomes next up the ladder include the vertebrates (amphibians, reptiels, birds, mammals etc)
In Skeletal System
Hydrostatic skeletons - muscles surround a fluid-filled cavity that supports the muscles.; when the muscles contract, they push against fluid in the body cavity, causing the b…ody to change shape (in annelids and certain cnidarians) Exoskeleton - external skeleton; a hard body covering made of chitin; move by using muscles attached to the inside of the exoskeleton; these muscles bend and straighten the joints (in arthropods) Endoskeleton - a structural support located inside the body; made of calcified plates; plates support and protect, the animal, and gives them a bumpy and irregular texture (in sea stars and other echinoderms, vertebrates, sponges)
big, medium and small this answer is not good look on wiki
Vertebrates have vertebra. . Invertebrates don't.
The group with the most species is that of the arthropods - insects, arachnids and crustaceans. But molluscs and the three groups of worms also make up a good part. Vertebrate…s is just another group like the arthropods for example - "invertebrates" is incredibly general. There are way more invertebrates than vertebrates.
