Invertebrates are the animals that do not have a backbone in the body.
It gives support to the entire animal’s body. This vertebral column houses the spinal cord, which is one of the essential organs of the body.
Examples of Invertebrates
- Flat and roundworms
- Ctenophore (comb jellies)
Insects are significant Examples of Invertebrates
These are six-legged animals with the ability to fly. They one of the largest classes of Invertebrates. They do not have a vertebral column. They also lack the spinal cord, but instead, they possess an exoskeleton made of the cuticle.
Examples of insects include
f) Termites like those on dogs etc.
These are the animals that have flexible, soft, and stout bodies. They are of different shapes and lack a vertebral column. Perhaps the vertebral column’s presence in these animals would not permit their flexible nature of the body. Most of them are marine, while few of them live in freshwater and land.
f) Squid etc. These are also examples of marine invertebrates.
Examples of echinoderms invertebrates:
b) Sea cucumber
c) Sea Urchin.
Arthropods: These animals have many legs and the legs are jointed. They also include insects, but those without the ability to fly will be discussed here.
These animals creep and crawl on the ground. They have annules or rings on the entire body, i.e., their body is cylindrical with many rings like annules. They do not have legs and also a vertebral column.
Examples under annelids
These are helminth parasites living in humans and other mammalian digestive tracts. They do not have limbs and also a vertebral column.
Examples of Platyhelminthes invertebrates:
a) Taenia solium
c) Wuchereria bancrofti.
Cnidarians: Jellyfish is an example.
From the list mentioned above, we can answer a few questions like
1. Examples of parasitic invertebrates: These include helminth parasites, ectoparasites (leech), lice, etc.
2. Examples of mollusks invertebrates: Corals, Starfish, octopus, etc.
