Insects, arachnids (spiders, scorpions), crustaceans (crabs, shrimp), and myriapods (millipedes, centipedes) belong to the phylum Arthropoda. This phylum is characterized by having jointed legs and a hard exoskeleton.
Phylum. Organisms in the same class belong to the same phylum, which is a higher taxonomic rank that groups organisms based on shared characteristics.
Phylum (Chordata), as class is located at a lower taxonomic level than phylum for classification of organisms.
Organisms that belong to the same class must also belong to the same phylum. Classes are subdivisions of phyla in the classification hierarchy of organisms.
Organisms belonging to the same family share the same order, class, phylum, and kingdom. For example, if two organisms are in the same family Felidae (cats), then they would also belong to the order Carnivora, class Mammalia, phylum Chordata, and kingdom Animalia.
The "true yeasts" are in phylum Ascomycota. There are some organisms commonly called "yeast" in Basidomycota as well.
Vertebrates belong to the phylum Chordata. This phylum includes organisms with a notochord (flexible rod) at some stage in their development, as well as a dorsal nerve cord and pharyngeal slits. Vertebrates are characterized by having a vertebral column, which gives them their name.
The phylum bulldogs belong in is, Chordate.
