Vertebrate is a category called a subphylum. Catfish belong to this subphylum or group. A catfish is a vertebrate.
All species of catfish are vertebrates. They belong to the classification of Fish, and all fish are vertebrates, having a backbone and internal skeleton.
Because they both belong to the Phylum Chordata in which they are both chordates (chordates are defined as organisms that possess a structure called a notochord, at least during some part of their development). Phylum Chordata Class Cephalochordata (lancelets) Family Asymmetronidae Family Branchiostomidae Subphylum Vertebrata (vertebrates) Class Cepalaspidomorphi Superclass Gnathostomata (jawed vertebrates) Class Chondrichthyes (rays, sharks) Euteleostomi (bony vertebrates) Class Actinopterygii (ray-finned fishes) Class Sarcopterygii (lobe-finned fishes & terrestrial vertebrates)
yes, cat fish is a vertibrate because it has a spine and bones projecting from its spine.
No, catfish aren't arthropods, they have a backbone and are thus in a different phylum, Chordata. Arthropods are characterized by having an exoskeleton; bones for an internal skeleton would indicate a non-arthropod.
YesYes. chameleons are in fact vertebrates who belong to the Class Chordate (vertebrates), Reptile Class.
Mammals
Osteichthyes is the class of vertebrates that has a swim bladder. It helps with their boyancy to help them move up and down in the water.
No, they are not the same, but all reptiles are vertebrates. Not all vertebrates are reptiles, they could be fish, mammals or birds.
Fish
The cockatoo is a bird, so it is in the vertebrate class Aves.
No.
Base at my researches the catfish and mudfish are the same
