I think the word you're after is just invertebrates. Vertebrates and those animals with a notachord are known as the Chordata - but those with neither spinal chord nor notachord are simply invertebrates.
The majority of the animal kingdom belongs to the phylum Arthropoda, which includes insects, arachnids, crustaceans, and other invertebrates with jointed legs and tough exoskeletons. Arthropods are incredibly diverse and can be found in nearly all habitats on Earth.
All phyla contain invertebrates. The only one that contains vertebrates is the phylum Chordata, but it also contains some invertebrates.
Vertebrates and Invertebrates. Vertebrates are animals with backbone which includes mammals, birds, reptiles, amphibians and fish. While invertebrates are animals without backbone. It includes an immense variety of animals from sponges, worms and jellyfish to mollusk and insects. another way is: carnivore and omnivore.
Arthropoda (Insects, Spiders, Crustaceans, etc.)
The simplest kind of invertebrates are typically single-celled organisms like amoebas or multicellular organisms like sponges, which have very basic body structures and lack complex organ systems. These invertebrates often have limited mobility and basic feeding strategies.
Yes, all fish of any kind are vertabrates belonging to the phylum chordata. Which means the animal has a spine and spinal chord. Humans also belong to this phylum of animals. Now when we start talking about shrimp and lobsters and such the answer becomes no, invertabrates have no spine and derive their shape from their exo-skeleton. Not all invertabrates however belong to the same phylum.
No. They have a skeletal system and a backbone.
Centipedes are arthropods, and all arthropods are invertebrates. They have an exoskeleton, with no backbone or spinal cord. They belong to the Phylum Arthropoda, which includes organisms such as insects, spiders, centipedes and millipedes, and crustaceans. Vertebrates include only some members of the Phylum Chordata: specifically, mammals, birds, fish, reptiles and amphibians.
All phyla except for one (Chordata) include only invertebrates, so 8 phyla include only invertebrates. The phylum Chordata is made up of the subphylum Vertebrata so therefore Chordata also has some species in it that are invertebrates. Humans are included in the phylum Chordata as well as the subphylum Vertebrata.
No. All mosquitoes are invertebrates, just as all arthropods are invertebrates. These creatures do not have backbones.
There are all sorts of animals that are invertebrates. However a rabbit is not one of them. A rabbit is a vertebrate.
Invertebrates. Butterflies are what is classified as an insect. Insects have no vertebrae; instead they have an exoskeleton.
