The simplest kind of invertebrates would be sea sponges. They are part of the phylum Porifera and are the only animals that do not have a nervous system at all.
All phyla contain invertebrates. The only one that contains vertebrates is the phylum Chordata, but it also contains some invertebrates.
No. They have a skeletal system and a backbone.
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.
Lady bugs are classified in kingdom animalia(all animals): they are part of phylum arthopoda and their class is insecta.They belong to the order of coleoptera.So yes they are invertebrates...
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.
All domestic and feral horse breeds belong to the same phylum as they are all the same species, just different breeds. The phylum for a horse is Chordata.
Yes. All vertebrates are in the Phylum Chordata.
The only vertebrate phylum is Chordata. All animals with backbones, or any bones at all, are chordates. Tunicates, which are filter feeding invertebrates with a spinal nerve but no bones, are also chordates.
The Mantis Shrimp and Mollusks are both invertebrates, but the mantis shrimp is technically in the phylum arthropoda (meaning jointed foot) and a mollusk is from the phylum mollusca (meaning soft body, but usually has a hard shell).
Hummingbirds are birds and, like all birds, they are vertebrates because they have a spine and spinal cord, and an internal skeleton. They belong to the Phylum Chordata. Mammals, birds, fish, reptiles and amphibians are all vertebrates.
