What are the charcterisics of a chordate?
At some point in their lives, a chordate will have a notochord, a nerve cord that runs down their back, and a slit in the throat area. The phylum name Chordata came from the notochord, a flexible rod that supports the back. They include fishes, amphibians, and reptiles.(I got this answer from my science textbook)Characteristic features of Chordata1. The chordates are one of the most diverse and successful of all animal groups.2. They are found in all regions of the world.3. They have a skeletal rod called Notochord, lying on the dorsal side of the body.4. There is a nerve cord that lies dorsally in the body, directly above the notochord.5. There is presence of Pharyngeal Gill slits atleast at the embryonic stage.6. Digestive system, Circulatory system and Nervous system are well developed.7. Those animals in which the notochord is replaced by a series of vertebrae are called as Vertebrates.8. Amphibia, Reptilia, Aves, and Mammalia are some of the classes of Phylum Chordata.They have bilateral symmetry, are coelomates, complete digestive system, and live in marine, terrestrial, and freshwater.All chordates have pharyngeal slits, which are openings that connect the inside of the throat to the outside of the neck, often used as gills. Their main feature, the notochord, a bundle of nerve fibers which connect the brain with the muscles and organs is present in all chordae's as well.In chordates, four common features appear at some point during development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
What is non chordate?
Non-chordates are animals that do not possess a notochord, which is a flexible rod that provides support along the back of chordates (animals with a backbone). Non-chordates make up the majority of the animal kingdom and include groups such as arthropods (insects, spiders), mollusks (snails, clams), annelids (earthworms, leeches), and many others.
What are two big groups of animal?
the two types of animals are the invertebrates and the vertebrates. invertebrates are the animals without a backbone. vertebrates are the animals with a backbone. for more information on the vertebrates....read ahead... these are the following features of a vertebrate: 1.presence of a tubular,dorsal,hollow nerve cord. 2.presence of a solid,rod-like structure called the notochord at some stage of life. 3.presence of a series of narrow,paired openings called gill slits.the gill slits disappear later on in most chordates. 4.presence of a postanal tail(tail behind the anal opening); the tail is reduced or absent in most chordates.
Do barracudas live in groups?
Barracudas live in groups until they are adults. Then these vicious creatures prefer to live solo.
What are animals without back bones are called?
(dovertebrates ) an animal without a penis or internal skeleton is called an dovertebrate an animal with backbone or internal skeleton is called a novertebrate
What All chordates have a notoriety pharyngeal pouches postnasal tail and?
All chordates possess four key features at some stage of their development: a notochord, pharyngeal pouches (or slits), a postanal tail, and a dorsal hollow nerve cord. These characteristics are evident in varying forms across different chordate groups, from fish to mammals. The notochord provides structural support, while pharyngeal pouches can develop into gill structures in aquatic species or contribute to various anatomical features in terrestrial species. The postanal tail aids in movement and balance, and the dorsal hollow nerve cord is crucial for nervous system development.
What is the significance of Protochordates?
The name Protochordates literally means 'the first chordates.' The chordates include fish, amphibians, reptiles, birds and mammals. The protochordates fall into two broad groups or subphyla - the Urochordata and the Cephalochordata. Urochordata The urochordata includes the group known as the tunicates - animals whose free-swimming larvae have a notochord* and a nerve chord. The adults are sessile - that is to say they are anchored to one place on the Reef. CephalochordataCephalochordates, or lancelets, are fish-like animals that have a notochord and nerve chord along the entire length of their bodies and which persist all their lives. * A notochord is a an elongated cellular chord enclosed in a sheath, that forms the primitive skeleton of chordate embryos (including humans) and adult cephalochordates.

Are mammals part of the chordate group?
Yes , mammals are part of chordate groups . Class mammalia is included in group Tetrapoda and they are part of vertebrata which is sub phylum of Chordata .
What classifications are tunicates and lanceletes?
Tunicates and lancelets represent the two groups of jawless fish. All other species of jawless fish have gone extinct.
What type of digestive do Chordata have?
Chordates are animals with backbones. Animal groups in the chordate phylum include fish, amphibians, reptiles, birds and mammals.Animals with backbones are the most highly evolved groups of animals, the most complex and complicated. They have interior skeletons and have bilateral symmetry. They have more advanced brains.An chordate takes in food through the mouth. The chordate has a mouth with a tongue. Some have teeth and some do not. It has a digestive system with stomach, intestines. Chordates eat plants and animals.
Does market segmentation literally separating the costumers into groups?
It does. The categorization can be as general as age groups (teens/ young adults/adults) or as specific as (Girl, 25, single and desperate).
Which chordate groups can regulate their body temperature?
Among chordate groups, birds and mammals are the primary groups that can regulate their body temperature through endothermy, maintaining a constant internal temperature regardless of external conditions. Some reptiles and amphibians exhibit behavioral thermoregulation, adjusting their body temperature by changing their environment, but they are not true regulators like birds and mammals. Fish and most other chordates are ectothermic, relying on external heat sources to regulate their body temperature.
What one characteristics distinguish most vertebrates from the other chordates?
Shafici daud barrow teacher of Biology. The features distinguish chordates from other groups of animals are: A) Single, hollow nerve cor beneath dorsal surface, in vertebrates, it differentiate into brain and spinal cord B) Notochord, flexible rod on the dorsal side of gut present at one stage in all cordates, displaced in vertebrates by vertebral column that forms around the nerve cord C)Pharyngeal slits(pouches) connect pharynx(between mouth and esophagus) D)Postanal tail extends beyond anus present at least in embryo
