The notochord is a flexible rod found in the embryos of all chordates, and is replaced later in life by the vertebral column and the main axial support of the body. If the animal you are referring to is an adult and lacking a "true notochord", it is still a chordate because the notochord has simply transformed into other parts of the body. However, if it is still an embryo and STILL has no notochord, it is not a true chordate.

Why dolphins and whales do not have gills?

Mammals: have fur or hair, give birth to live young, and nurse their offspring with milk. Birds: have feathers, lay hard-shelled eggs, and are warm-blooded. Reptiles: have scales, lay eggs with soft shells, and are cold-blooded. Amphibians: have moist skin, lay eggs in water, and undergo metamorphosis from larval to adult stage. Fish: have scales, breathe through gills, and are cold-blooded.

A Chordate is a animal with a notochord. They do not need to have spines- they just need to have a spinal cord. Fish, Reptiles, Mammals, Birds, and Amphibians are all members of the Chordate phylum. There are also invertabrates closley related to these members of the Chordate phylum that are Chordates.
What is the definition of chordate?

What animal has jointed legs gills and no backbone?

What is a chordate animal?
Chordates, members of the phylum Chordata, are deuterostome animals possessing a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail for at least some period of their life cycles. Taxonomically, the phylum includes the subphyla Vertebrata, including mammals (and thus humans), fish, amphibians, reptiles, birds; Tunicata, including salps and sea squirts; and Cephalochordata, comprising the lancelets.The phylum Hemichordata including the acorn worms has been presented as a fourth chordate subphylum, but it now is usually treated as a separate phylum. It, along with the echinoderm phylum, including starfish, sea urchins, and sea cucumbers and their kin, are the chordates closest relatives. Primitive chordates are known from at least as early as the Cambrian explosion.There are more than 60,000 living species of chordates, about half of which are bony fish of the class osteichthyes. The world's largest animal, the blue whale, and fastest animal, the peregrine falcon, are chordates.
