no
Vertebrates do not have exoskeletons. However, they do have internal organs, vertebral columns, and tails. Lampreys are vertebrates that also do not have jaws.
No, all vertebrates have an internal skeletal system although some are also externally armoured eg Armadillos and Turtles
LICE
Arthropod is a phylum within the vertebrate kingdom. Arthropods have a backbone.
No, a regular turtle is not an arthropod. Turtles belong to the class Reptilia, while arthropods belong to the phylum Arthropoda, which includes insects, spiders, and crustaceans. Turtles are vertebrates, meaning they have a backbone, while arthropods are invertebrates with exoskeletons.
all vertebrates are chordates because vertebrates are the sub- group of phylum chordates and also it follow one of the important feature of the chordates i.e. presence of notochord whereas all chordates are not vertebrates because some chordates are cephalochordates, urochordates.
some are, some aren't. Reptiles are vertebrates and cold-blooded.
Some of the reptiles that are vertebrates: -snake -lizard -tortoise -crocodile
Vertebrates belong to the phylum Chordata, which is a group of animals characterized by the presence of a notochord at some stage in their development. This phylum also includes other subphyla like tunicates and lancelets, in addition to vertebrates.
An arthropod
Yes, the slater, also known as the woodlouse or "roly poly bug" is an arthropod, of the family Armadillidiidae. They are among the crustacean arthropods that can be found on land, though they need to be in a moist environment. Sometimes they are confused with the pill millepede which looks pretty similar (and is also an arthropod).
All true whales are mammals, therefore also vertebrates.
