Is an oyster an invertebrate animal?
It has complex organs, it is a multicellular organism, it breathes, it needs to eat, it reproduces. Basically, if it's alive and not a plant/fungus, it is an animal.
yes, a sea urchin can kill you by its spikes. So be careful if you go swimming in the sea, make sure you bring goggles so you can look in the water if there is a sea urchin. If there is a sea urchin, make sure you don't bother it either get out of the water or if you want to continue your journey, step around or over it.

What do Invertebrate Chordates eat?
The term vertebrate, refers to animal life which have a backbone. Without knowing which particular species you were referring to, this question may not be answered in the way you had in mind.
Vertebrates can be herbivores, omnivores, and carnivores.
For instance, when I decide to feed my snake I put him in an empty fish tank. You can use a larger box if you wish, but then I just drop the mouse (the snake's meal) in the tank (or box) and the snake bites it and spins.Then the snake just opens his mouth and inch by inch, he slides it down and I mean inch by inch: it takes a long time.
Do invertebrates have a respiratory system?
Yes, Invertebrates have respiratory system.
upto phylum Annelida no special respiratory organs are found. The respiratory system first appears in phylum Arthropoda. Trachea, Book lungs, book gills are respiratory organs in Arthropodans.
Mollusca have gills.
Echinodermata have Tube feet, Respiratoryy tree and bursae
Do sea urchins live in warm water?
No, atually they live in massive groups, searching for kelp and other sea grasses to munch on. A large mass of urchins can clear massive kelp forests in a short amount of time. Most urchin groups live in shallows, but some species prefer deeper waters.
Are stingray considered vertebrate or invertebrate?
Rays such as the manta ray are in fact vertebrates. They have a skeleton made primarily from cartilage. They are closely related to sharks, who also have a skeleton of cartilage.
What is the name given to the simple brain of an brain of an invertebrate such as planarian?
***Nerve Set***
What group of invertebrates have the greatest number of species?
Beetles have more diversity among them than do any other group of animals.
What invertebrate group does a ant belong to?
A tarantula belongs to the Arachnid family. We know this 'cause tarantulas have eight legs.
Ain't spiders awesome?
How big is a sea urchin spike?
Depending on the species, sea urchins range in size from a few inches across (small rock-boring urchins) to a foot or more across (pencil urchins and venomous hollow-spined urchins).
THATS NOT HELPFUL!!
What part do invertebrates lack?
Vertebrates (like humans) have a backbone. Invertebrates (like worms) lack a backbone.
Is the Black Sea urchin endangered?
No, despite losing 95-99% of all individuals in the Caribbean to a disease in 1983-1984, the black sea urchin has never been listed as Endangered under the US Endangered Species Act.
While there is no denying their importance to the reef community, and the impact their absence had during the outbreak, marine invertebrates like urchins can only be listed on the species level, not by population or region. Without enough research to support multiple species of black sea urchin there has never been enough evidence to deem listing the Caribbean population.
ctenophora are often found around piers. A good place to look would be the nearby sailboat marina if on the coasts. Are only marine (seawater). Not found in lakes, rivers, etc. If you see jellyfish ctenophores may be nearby
Is a woodpecker a vertebrate or an invertebrate?
Yes, as are all bird species.
Woodpeckers have spines, so are vertebrates.
Invertebrates have a hard outer shell, called an exoskeleton. Muscles are attached to the inside of the exoskeleton, and contraction of these flexes the joints.
It depends on what animal it is. A jellyfish, for instance, moves by swaying its body back and forth. A caterpillar uses its small legs to move.
I hope this helped... :D
