Why do we have to study Invertebrates?
Studying invertebrates is crucial because they make up the vast majority of animal diversity on Earth, playing essential roles in ecosystems as pollinators, decomposers, and food sources for other animals. Understanding their biology and ecology helps us address environmental issues, such as biodiversity loss and ecosystem health. Additionally, invertebrates can provide insights into evolutionary processes and serve as models for research in various scientific fields. Their study also has practical applications in medicine, agriculture, and biotechnology.
Many people with reef tanks have sea urchins. They help clean the algae in the tank and off the rock.
What eats the strawberry anemone?
Chopped silversides, shrimp, krill and mussels. If it's being kept as a pet, fresh chopped fish from your grocery store. Feed it this once a week or twice a month...Cold water anemones have much slower metabolisms.

Phylum Chordata: Subphylum Cephalochordata and Urochordata along with the subphylum Craniata
What is the difference between the nervous system of vertebrates and invertebrates?
- Vertebrates have vertebra.
- Invertebrates don't.
YES! Lambs are vertebrates, which means they have backbones... most mammals are.
Reptiles are most invertebrates
An invertebrate is an animal without an internal skeleton. Ants do not have an internal skeleton so they are invertebrates by definition.
What are the Most complex group of invertebrate?
the most complex group of invertebrate is cnidarians
Are invertebrates herbivores carnivores or omnivores?

How are all invertebrates alike?
All invertebrates have no backbone and most usually have a had covering much like a wax water proof covering, also all invertebrates can be traced back to have ancestors that were once only aquatic.
How does a sea urchin trap its prey?
they hide behind sea plants and sneak up on the prey. they attack when they see a prey. usally they cacth them but not always
no, mammals are grouped together because they all posses hair, lungs and mammary glands (hence the name) to produce milk, and a few other features. the urchin does not posses any of these quality's and therefore is not a mammal
