Question

Make a list of invertebrate phyla. Give one example of each.

Answer 1

Hint: Invertebrates are the organisms that neither have nor evolve a vertebral column (backbone or spine) obtained from the notochord. They are multicellular. All the cells have different roles in keeping the animal alive.

Complete answer:
Invertebrates incorporate all organisms aside from the subphylum Vertebrata. Some assumed invertebrates such as the Tunicata and Cephalochordata are more closely linked to vertebrates than to the rest of the invertebrates.
Phylum Porifera: Example -Sycon, Spongilla, Euspongia
Phylum Coelenterata: Example - Hydra, Physalia, Obelia
Phylum Ctenophora: Example - Pleurobrachia, Ctenoplana
Phylum Platyhelminthes: Example - Taenia, Fasciola, Planaria
Phylum Aschelminthes/Nemathelminthes: Example - Ascaris, Wuchereria, Ancyclostoma
Phylum Annelida: Example - Pheretima, Hirudinaria, Nereis
Phylum Arthropoda: Example - Cockroach, Butterflies, Prawn, Centipede
Phylum Mollusca: Example - Octopus, Neopilina, Pila, Unio, Pinctada
Phylum Echinodermata: Example - Asterias, Ophiothrix, Echinus, Holothuria
Additional Information:
-Invertebrates do not have a backbone.
-They are ectotherms (cold-blooded).
-Great variation in size. Malarial parasites are the smallest invertebrates while the largest one is the giant squid.
-Some kind of invertebrates can live their life on land. Examples include insects, spiders, and worms. These invertebrates need to have special structures to live on land.
-Many invertebrates change form during their growth and this process is referred to as Metamorphosis.
-Many invertebrates are soft-bodied, while some like arthropods and molluscs possess hard exoskeleton for supporting and protecting their body.

Note: -Invertebrates set the path for the evolution of other organisms as simple transformations started taking place. These straightforward transformations led to complex living beings in the form of vertebrates.
-97% of all the animals are invertebrates. Most triumphant invertebrates living on the land are Arthropods.
