Yes, all mammals, reptiles, avians, amphibians, insects, arachnids, crustaceans, piscines, gastropods, cephalopods, annelids, etc. are all animals.
Arthropods, crustaceans, arachnids, and some fungi and bacteria have exoskeletons.
The major groups of arthropods are insects, crustaceans and arachnids.
"True crabsare decapod crustaceans of the infraorder Brachyura," (http://en.wikipedia.org/wiki/Crab) and "many varieties of shellfish (crustaceans in particular) are actually closely related to insects and arachnids" (http://en.wikipedia.org/wiki/Shellfish).
Insects are animals, so they belong to the kingdom Animalia.
No. Arthropoda is a phylum, containing the classes Insecta, Arachnida, Crustacea and Myriapoda - insects, arachnids, crustaceans and centi/millipedes. So all insects are arthropods but not all arthropods are insects. ^^
Yes. Some alien races have animal characteristics (i.e. mammals, reptiles, amphibians, insects, arachnids, gastropods, reptomammals, reptavians, crustaceans, avians, mammavians, etc.).
Ocean crabs are not amphibians, they are crustaceans. Body crabs (crab lice) are also not amphibians, they are arachnids.
* birds * reptiles * fish * amphibians * invertebrates, including crustaceans, molluscs, insects, arachnids, etc
Mollusca is indeed a very large phylum, with bivalves, gastropods, cephalopods, monoplacophorans, scaphopods, aplacophorans and chitons. However, this is not nearly enough to cap the largest phylum, which is ....... Phylum Arthropoda, with about 1 million insect species, and plenty of myriapods, arachnids and crustaceans, not to mention horseshoe crabs and pycnogonids.
No. They are arachnids.
Vertebrates have spines and invertebrates don't. The groups of vertebrates are mammals, birds and fish, reptiles and amphibians. Invertebrates are insects, arachnids, molluscs, crustaceans etc.
arachnids, insects, crustaceans, etc.
No, frogs are amphibians.
Arachnids and crustaceans are both arthropods and both have exoskeletons.
No they are from the family arachnids.
Arthropods (insects, arachnids, crustaceans, and the 'pedes), mammals, birds, reptiles, fish, amphibians, and soft invertebrates. I can't remember the eighth one, though...
Yes, crustaceans do have an exoskeleton, as do all arthropods, including arachnids, insects, and crustaceansm
