- The domesticated dog (Canis familiaris) belongs to which of the following chordate classes? class Chondrichthyes (the cartilaginous fishes) class Osteichthyes (the bony fishes) class Reptilia (the reptiles) class Amphibia (the amphibians) class Mammalia (the eutherian mammals)chordate Tunicates Lancelets Which statements are true about the phylogeny of chordates? Lobe-finned fishes feature lungs and vertebrae. Tunicates and lancelets have vertebrae, but they lack jaws. Mammals and reptiles have both an amniotic egg and hair. The amniotic egg in reptiles and mammals is a synapomorphy. Only mammals, reptiles, and amphibians have living species. MacBook Air 80 F2 F3 F4 F5 F6 F7 2$You believe that an adult animal you are examining is a vertebrate but concede that it may be an invertebrate chordate. Which of the following would ensure that you are indeed looking at a vertebrate? OIt lacks a notochord. It has a dorsal hollow nerve cord. It uses its pharyngeal gill slits for respiration. Its notochord functions as an endoskeleton. It is able to swim.
