First something has been divided into phylums - one group. But that wasn't enough, There were still things in that group which needed to be further sorted, so a sub-phylum was created.
Let's say you have one group - cars. That's your phylum.
Then you have sports cars, that's a sub-phylum.
Frogs belong to the subphylum Vertebrata, within the phylum Chordata. This subphylum includes organisms with a backbone made of vertebrae, which are bony or cartilaginous structures that provide support and protection for the spinal cord.
The lancelet belongs to the subphylum Cephalochordata within the phylum Chordata. They are small, fish-like marine organisms that exhibit characteristics of chordates, such as a notochord and a dorsal nerve cord.
Arthropods are divided into three subphyla: Chelicerata, Myriapoda, and Pancrustacea (which includes Crustacea and Hexapoda). Each subphylum represents a distinct group of arthropods with specific characteristics and differences in body structure and function.
Vertebrata
Chelicerata is a subphylum of the phylum Arthropoda. It contains organisms like spiders, ticks, and scorpions. Organisms in Subphylum Chelicerata have a cephalothorax and a posterior abdomen. They have six pairs of appendages on their cephalothorax: Chelicerae, pedipalps, and four walking legs. Chelicerae are pinchers that crush food, and pedipalps are appendages that control food. They do not have mandibles, which are jaws, and they don't have antennae, so organisms in Subphylum Chelicerata technically aren't insects.
Mollusca is a phylum, not a subphylum.
The subphylum of the koala is Vertebrata.
The subphylum of the african elephant is vertebrata
Snakes belong to the subphylum vertebrata.
ameoba belongs to the subphylum 'sarcomastigophora' of the phylum protozoa
The subphylum of millipedes and centipedes belong to the subphylum myriapoda. There are over 13,000 species that are terrestrial and they belong to the Animalia kingdom.
No. Insects are the the subphylum hexapoda and millipedes are in myriapoda.
Frogs belong to the subphylum Vertebrata, within the phylum Chordata. This subphylum includes organisms with a backbone made of vertebrae, which are bony or cartilaginous structures that provide support and protection for the spinal cord.
Vertebrata is a subphylum of the phylum Chordata. Subphylum Vertebrata contains animals like fish, amphibians, reptiles, mammals, and birds. Animals in subphylum Vertebrata have craniums, increased cephalization, and endoskeletons, and they typically have vertebrates, although there are some exceptions, like hagfish.
