Is an animal with a backbone and gills but no notochord still a chordate?

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 do you need nomenclature?
THERE ARE THREE REASONS FOR GIVING SCIENTIFIC NAMES TO THE ORGANISMS.1. Different names for the same organismDiffernet people gave different names to the same organism in the past.There were no system of giving the names to the organisms.DifferentReigons had different names of the same organism.For example:Ø Piyaz is name of Onion in URDU.It had different reignol names in Pakistan likeGanda.bassal and vassal.Ø Different countries have different names for the same plant.For example: amaltas, argvad, gurmala, golden shower and purging cassia are different common names of the same plant.2. Same name for different organismIn some cases, a single name is given to several different plants and animals.For example:Ø Dozen of plants with bell shaped flowers are named blue bell.Ø The name Black bird is given to the crow and raven.3. Common name without scientific basisØ Common names has no scientific basis. Fish is a vertebrate animal. It has bones, gills and fins. Silver fish, cray fish, jellyt fish and star fish do not have these characters. So they cannot be placed in fishes.

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.
