No. A snake has a spine (backbone) so it is not an invertebrate.
Are the Sea Urchins a type of chemical weathering?
No. Not even close. Sea urchins are small, herbiverous marine invertebrates with spines.
One way invertebrate in general contribute to the process of life?
I think you are talking about tiny animals without skeletons. If so, these are a/the critical component to the entire food chain. For example we are talking about the ocean's tiniest creatures such as plankton that in massive abundance feed to many species of sealife to even fatham. The greatest mammals on earth - whales - depend on this tiny creature by the ton - filtering them from the ocean waters as a rich source of nutritition.
What ensures sea anemone do not self fertilize?
In monoecious species, male gametes mature earlier than female gametes so that self-fertilization does not occur. This is called protandry.
What are the nine invertebrate sensory receptors?
baroreceptors,chemoreceptors,georeceptors,hygroreceptors,phonoreceptors, photoreceptors,proprioreceptors,tectilereceptors,thermoreceptors
How many invertebrates can you name which have shell?
Certainly not all of them, as marine biologists are constantly finding new life forms in the seas. However: crabs, lobsters, snails, and nautilus's have shells, also known as exoskeletons.
How many wings does a monoplane have?
The is only one pair of wings on a monoplane. There would be one wing on each side of the plane.
Do pregnant stick insects eat the male?
No. I have breed Stick insects for 2 years. In fact in some species the female carrys the males round on their backs.
Black long spine urchin with white spines?
Well, the white colour might have came from old age or chemicals in the sea.
What is the body plan of an invertebrate Chordate?
The body plan of an invertebrate Chordate is quite unique as it does not entail a backbone. It has a hollow dorsal nerve cord and post-anal tail among other crucial features.
Is a lobster heavier than a sea lion?
Sea lions are typically hundreds of times heavier than lobsters.

What provides support to an animal that lacks bones?
Most invertebrates/bone-lacking animals live underwater. So they do not need bones for support. Instead they just make rippling wave-like movements to move along with the current of the water.
Land-animals with no bones, such as insects, have an exoskeleton.
What invertebrate groups are segmented?
Arthropods' bodies are segmented into three parts. The head, the thorax, and the abdomen
Well I wouldn't test it... it probably would hurt though
When an invertebrate reaches the stage it most likely stops growing and can begin reproduction?
yes it dose
What is the prime difference between vertebrate gills and invertebrate gills?
Vertibrates have bones while invertibrate don't have.
Vertebrates and invertebrates?
a vertebrate is a living organism with a backbone
and an invertebrate is a living organism without a backbone
