Invertebrates

Parent Category: Animal Life
Invertebrates are animals that lack a spinal cord, such as insects. Ask questions here about these organisms that make up 95 percent of all animal life.
Ecdysis is the moulting of invertebrates. So many invertebrates  molt, such as crabs, lobsters, spiders, bees, centipedes,  dragonflies, grasshoppers, roaches, mantids, and the most well  known, cicadas.
In order for a living organism to be classified as a vertebrate it  must have a backbone, a central nervous system that is partly  enclosed by this backbone, and also a muscular system.   Silverfish are insects and crabs are crustaceans, both  invertebrates, they lack a backbone.
They have a spiny thorns so they will eat it
Diatoms are unicellular. There cell walls are made of two overlapping halves.This credit goes to http:/users.rcn.com/jkimball.ma.uktranet/biologypages/p/protists.html
No, they don't. They lay their eggs in a sac, under water.  :) 
No. You either have a backbone, or you don't. Simple as that.
They can't live in saltwater because their body just doesn't  support it. They reproduce and everything differently, and probably  wouldn't live in salt water.
Yes it is an invertebrate because it does not have a backbone.
Sea urchins or urchins are small, spiny, globular animals that,  with their close kin, constitute the class Echinoidea of the  echinoderm phylum.     Echinus is the genus that contains the common sea urchin.
The praying mantis is an insect in the Family Mantidae.
i only know that they have eight legs rather than insects who have 6
They are vertebrate.They are Vertebrates because they have a backbone invertebrates are animals that dont have a backbone i hope this helped you x
They are part of the excretory system. They generally filter  nitrogenous wastes from the blood and their function is analogous  to the kidneys in mammals.
The crab is in the crustaceans.Crabs are grouped in various ways with other arthropods, being in a  major taxonomic group called a phylum (Arthropoda) all of whom are  characterized by hard exoskeletons, joint appendages, and segmented  bodies. Since arthropods are such a major group, branching ...
A paramecium is shaped like the sole or bottom of a lady's slipper.
most of time good it depends on how you cook it
Invertebrates are animals without the backbone or spine. Animalssuch as jellyfish, squid etc. Basically things in the groups ofcrustaceans, molluscs, arthropods, arachnids, and insects. Thereare plenty more, but that's just a few.
They are invertebrates
Yes, cnidarians are invertebrates.
The comparison between the digestive system in vertebrates and  invertebrates is diverse. They are slightly similar in that they  start at the mouth and end up at the anus. However, the digestive  system of vertebrates is much complicates and has more organs.
There are quite a few disadvantages of filter feeding for  invertebrates. One is that this food might not be safe to eat.
This is from wikipedia Arthropoda - insects, arachnids, crustaceansNematoda - round wormsMollusca - squid, snails, bivalvesAnnelida - segmented worms (earthworms, leeches, polychaetes)Nemertea - ribbon wormsPlatyhelminthes - flat wormsRotiferaAcoelomorphaCtenophora - Comb jelliesCnidaria -...
the name you are looking for is an animal without a back bone
Worms , slugs , snails , earwigs and snails
Characteristics of diatoms:     All species are unicellular or colonial coccoid algae. None are  free-living flagellates.  The only flagellate cells produced are the male gametes (=  sperm, spermatozoids) of 'centric' diatoms. These have a single  forward-pointing flagellum, which bears...
The phylum of mealworms is Arthropoda.
Yes, sea monkeys are actually brine shrimp.
Sea anemones can be dangerous depending on their sizes and their level of toxic.
spikes and they do not have skin they have a Shell
ALittle bit Kind of Smooth And Just 2% Rough
yes they do they hatch into swimming larvae
Snails, slugs, beetles, ect. Anything without a backbone, or with an exo-skeleton. Also BACTERIA..(:
I am pretty sure they survive in both the surface zone and the Deep zone.
Toads have a vertebrate column, and are therefore vertebrates.
Invertebrates have no vertebral column
they can be, but the ancient Greeks and Romans used to eat them as a delicacy.
I don't know what a invertebrate is so, I don't know.
Invertebrates have no backbone, muscles are attached to outer shell.
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.
Cnidarians live in salt waters or fresh waters. They have a simle nervous system and they have stinging cell called nematocysts. Thet have two embryonic cells, the epidermis and gastrodermis which are separated by the mesoglea.
No, a sea urchin and a sea anemone are two different sea creatures nothingalike.   They do have some alike characteristics.like they both use their long tentacles , or spikes for protection.
No reptile or amphibian is an invertebrate.
one lives in salt water and the other in fresh water.
Ants are not arachnids. They belong to the insect group becausethey have six legs, and three body parts, the head, thorax, andabdomen. And yes. Ants are invertebrates. They don't have a spine,instead they have an exoskeleton.
No, no insects have a vertebrae.
No, to be an invertebrate it must be a living animal (without a backbone) of which a computer is not!
like fish but i'm not sore if it is nince answer
  == A sea urchin is in fact neither a sea urchin is a Detritus or a animal that ==   eats decomposing plants and animals making it also somewhat of an omnivore
There are several other names used when referring to nephridia.  Some of these include metanephridium, protonephridia, and  metanephridia. It is basically an invertebrate organ that performs  similar functions as the kidney.
Nephridia are organs that secrete waste products, similar in general purpose to the human kidney.
i dont no just LOOKING 4 THE ANSWER HERE SO DONT TRUST THIS ANSWER.yes they o leave there young
  i guess u should ask some one that is in science
Shrimps do not have back bones. Therefore, shrimps are invertebrates.
I think it can vary though many are pale or green. If you mean the Plankton from Spongebob Squarepants, he's green.
  Plankton can be found in the Pelagic zone of oceans, seas, and bodies of fresh water.
it is 356 feet long
An invertebrate animal is an animal which has no spine like a slug. (P.S. Unlike most believe a snake does have a backbone)
Squirrel monkeys are vertebrates because they have a spine. Vertebrate animals have spines. Invertebrate animals lack spines.
Abdomen, antennae, eyes, head, legs, mouthparts, thorax, and wings constitute the different parts of a leaf bug. The term in question serves as a general term for a member of the Hemiptera true bug insect order. It therefore will reference an invertebrate whose skeleton is on the outside, not the...
Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. Vertebrates are animals that are any species of animals within the subphylum Vertebrata (chordates with backbones).
4 stages of development
Answer So far the closest animal to the sea urchin is the starfish (seastar). Sea cucumbers and sand dollars are also closely related to the sea urchin.
I do not know if there is an exact percentage, but I do know thatthe of the known species, the most are invertebrates. This isbecause bugs are invertebrates. There are so many different speciesof bigs, just the insects alone, that we cannot find and name themall. Also you have many other groups of...
The Red Capped Robin eats insects and other invertebrates.
The body form is like a jellyfish. There are two forms: swimming medusae and sessile polyps.
Invertebrates are actually very common. Invertebrates are broken  down into multiple groups that include shrimp, spiders, snails,  worms, jellyfish, and sponges.
No. Invertebrate means "having no spine" - therefore an otter, like all mammals, is a vertebrate.
Diatoms are single celled algae.
Both have their mouths (oral surface) at the bottom of their bodies. However, a sea urchin has teeth called aristotles lantern that scrapes algae off rocks, while a sea star ejects it stomach around the contents of its food to digest its prey.
Sea Urchins are multicellular animals, phylum echinodermata.
No, diatoms are related to the golden-brown algae (Chrysophyta), but are generally classified in their own group, the Bacillariophyta.
lions, birds, frogs, dogs, cats, fishes. ( vertebrates) spiders, jellyfishes, sea stars. ( invertebrates)
Echinoderms are marine invertebrates, they dwell under the sea unlike that of others that mostly live in land.
since rats are mammals, they are most definitely vertebrates.
around 2300 pounds
yes,ofcourse it is a vertebrate. it is a marine organism.the plesiosaur fossil has a type ---------- named...........jurrasic plesiosaur
They eat zooplankton, krill, and smaller fish.
