What happens if an invertebrate loses a body part?
Generally, they become an amputee. A few invertebrates can grow back a body part.
Firstly , what is invertebrate ?? Animals without backbone right ?? Yes . So butterfly .... is it an vertebrate or invertebrate ? YES !
What is a starfish's reproduction?
A starfish can reproduce by mating with another starfish or asexually. Asexual reproduction is usually done after a starfish experiences dismemberment. The dismembered arm can grow into a whole new starfish.
What is the name of a sea creature that does not have a backbone?
Any aquatic invertebrate could be described that way. Perhaps the term "marine invertebrate" is what you are looking for.
Invertebrate sea life includes the following phyla:
- Acoela;
- Annelida, (polychaetes and sea leeches);
- Brachiopoda;
- Bryozoa, also known as moss animals or sea mats;
- Chaetognatha;
- Cephalochordata;
- Cnidaria, such as jellyfish, sea anemones, and corals;
- Crustacea, including lobsters, crabs, shrimp, crayfish, barnacles, hermit crabs, mantis shrimps, and copepods;
- Ctenophora, also known as comb jellies;
- Echinodermata, including sea stars, brittle stars, sea urchins, sand dollars, sea cucumbers, crinoids, and sea daisies;
- Echiura;
- Gnathostomulids;
- Gastrotricha;
- Hemichordata;
- Kamptozoa;
- Kinorhyncha;
- Loricifera;
- Merostomata; also know known as horseshoe crabs;
- Mollusca, including shellfish, squid, octopus, whelks, Nautilus, cuttlefish, nudibranchs, scallops, sea snails, Aplacophora, Caudofoveata, Monoplacophora, Polyplacophora, and Scaphopoda;
- Myzostomida;
- Nemertinea (ribbon worms);
- Orthonectida;
- Phoronida;
- Placozoa;
- Porifera (sponges);
- Priapulida;
- Pycnogonida (sea spiders);
- Sipunculida;
- Tunicata, also known as sea squirts;
- Some flatworms of the classes Turbellaria and Monogenea;
- Xenoturbella;
- Xiphosura.
I notice that this was originally posted in "aquatic mammals". All mammals are vertebrates so none of the aquatic mammals would lack a backbone.
An example of an invertebrates?
Porifera--sponges
cnidaria--jellyfish, sea anemone, etc.
nematoda-- roundworms (often parasitic)
arthropoda-- insects, lobsters, spiders, etc.
mollusca--snails, clams, squids, etc.
echinodermata-- sand dollars, sea stars, sea urchins, etc.
Is a tadpole a vertebrate or invertebrate?
tadpoles are not vertebrates because they do not have a backbone.
No.
They have a rudimentary brain, eyes; a mouth and gills, but none of it is organized into a head.
No. They don't bear live young, they don't have hair. They are a species of fish.
No, eels are actually a type of fish. Eels breath water and not air, are cold blooded and lay eggs. A mammal breaths air, is warm blooded, gives birth to live young, has body hair and the females nurse there babies with milk. Humans, dogs, cats and horses are types of mammals.
No
How do you catch the sea urchin?
get stung and then you can get it but get it by the bottom and i think it doesnt sting
Circulation in cnidarians consists of?
Circulation within Cnideria isn't 'realy' circulation. They do not have any organs or special tissues that work for circulation. Organisms in this phyla would get their nutrients through diffusion. Since these organisims are never far away from water they just get their nutrients through the water that they are in.
How long does it take to walk around the Omaha Zoo?
if you want to see all the attractions and still get your moneys worth it will take a few hours it depends if it counts to go inside every place then it will take much longer they are adding more stuff which means longer time to be there and sometime there are trains to take you place to place
What invertebrates has a fleshy pad for movement?
A slug has no backbone i think
Frogapple
Slug and snails but I'm not sure what its technical term is
All mature diatoms lack flagella, but their gametes may be either amoeboid or flagellated.
Which biological groups contain only invertebrates?
arachnids, arthropods etc all animal are invertebrates unless if they are a mammal, reptile, bird, amphibians or fish
What invertebrate has an internal skeleton?
There is no such thing as an invertebrate with a skeleton. The definition of "invertebrate" is "one without a backbone."
Are there a lot of sea anemones?
Not many, but there are types like Medittaranean, Plumose and Beadlet
What is an example of an Invertebrate chordate?
Characteristics of the invertebrate Chordata:-
1)Bilaterally symmetrical.
2)Body has more than two cell layers, tissues and organs.
3)Body cavity a true coelom.
4)Most possesses a through gut with a non-terminal anus.
5)Body monomeric with no head or jaws.
6)Possess at some stage of their life a hollow dorsal nerve tube.
7)Possess at some stage of their life a dorsal cartilaginous rod called a notochord.
8)Possess at some stage of their life gill slits in the parangeal region.
9)Has a partially open circulatory system.
10)Without excretory organs.
11)Reproduction normally sexual and gonochoristic.
12)Feed on a variety of organic materials.
13)All live marine environments.
Examples of an invertebrate chordate are Fish, Amphibians, Reptiles, Birds and Mammals.

More specifically, a box fish, cow fish, or trunk fish. Characteristics include the following:
With their rigid bodies propelled "helicopter fashion" by tiny, rapidly moving fins, these fish are an amusing sight as they motor about the aquarium.
Their appeal is heightened by an "alert" face, and, in many species, horn-like projections at the head and rear of the body (see color insert for photo).
Although immune from attack by most large predators due to their hard covering of bony plates, box- and cowfish are slow moving and their rapidly undulating fins seem to draw attacks from smaller fish. The skin over the rigid plates is, strangely, quite sensitive and also suffers from the attentions of aggressive tank mates.

What are the three regions of an insect body and their respective locations?
Abdomen, head, and thorax are the three regions of an insect's body. In terms of their respective locations, the head comes first, with the abdomen following, and the the thorax at the end.
What mode of nutrition do diatoms have?
Most Diatoms are Photosynthetic but some have evolved to be heterotrophic
