Is a ray a jawless fish?
Jawless fish are included in subphylum Vertebrata, but most jawless fish do not have whole vertebrae. Hagfish, for instance, do not have vertebrae at all, and lampreys have only reduced vertebrae. So, no, most jawless fish are not vertebrates.
Give you some example of jawless fish?
Most fish are not jawless. There is a small group of very primitive fish called Jawless fish (Agnatha). However, they make up a very small proportion (<1%) of the fish species on earth. Jawless fish are things like lamprey and hagfish. All other fish, like trout, salmon, tuna, sharks, rays, cichlids, goldfish, etc, etc, have jaws. See the related link for more information on the primitive jawless fish.
Is a lamprey a amphibians?
No, a lamprey is not an amphibian. A lamprey is a fish, more specifically a jawless fish. It is one of the earliest forms of fish that is still alive today.
Are killer whales vertabrates or non vertabrates?
More than 95 percent of animals are invertebrates,or animals that doesn't have backbone.And vertebrate just have few,like,jawless fish,bony fish,cartilage,amphibians,birds,reptils,and mammals.So you can see that killer whales are mammals.The answer of your question is the killer whales are vertebrate.
What are facts about jawless fish?
Jawless fish are also called Agnatha which is Ancient Greek word means â??no jawâ??. They have long bodies but do not have backbones and look like eels.
Why do more advanced fish have symmetrical tail fins?
Fish have a symmetrical tail, because they are a more advanced species. Sharks are less advanced because they are always moving!
Is a lamprey a vertebrate?
No, a lizard is not and amphibian it is a reptile because if it was and amphibian it would live in water. Plus it has scales...
What kind of skeleton does a jawless fish have?
Agnathans are the jawless fish. They are usually fairly small (a few centimeters in length.) They consist of lancelets and tunicates. They have a notochord which is like a backbone, but it is more flexible than bone. Tunicates are enveloped by a tough tunic around their bodies. Other than that, they have no other bones.
What is the difference between primitive fish and the most advanced types?
primitive fish are ones that have more skeleton weres advanced types tend to be more of muscles
What is vertebrate and invertebrates?
invertebrates are animals that have no back bone. Examples include...jawless fish. Vertebrates have back bones and are more common like humans!
What are Vertebrate how are they classified?
Vertebrates or chordates are classified into 7 classes, which are bony fish, cartilage fish, jawless fish, mammals, amphibians, reptiles, and birds. Bony fish are the most common type of fish and include the most amount of species in the vertebrates class. Cartilage fish are commonly known as rays, scates, and sharks. Jawless fish are very rare and are known to be the ancient fish. Reptiles are categorized into Chelonia-turtles/tortoises, squamata-snakes lizards, crocildilians- crocs, alligators and caimen and some others. Amphibians are urodela- salmanders, newts, anura- frogs and toads, apoda- Caecilians. Mammals are dogs, cats, whales, dolphins, horses...... you probably know this. Birds or aves are pretty simple. Birds are birds!! Animals that are not vertebrates include molluscs, arthropods, cnidarians, poriforans, nematods, platyhelmithes, annelids, and way more. there are more invertebrates than vertebrates.
What evolutionary development do scientists think occurred in the Cambrian period that gave rise to more complex fish?
They theorize that during this period the first of three gill arches on a jawless fish evolved into the first jaws.
