Do all animals have a tail?
Yes, all chordates have a tail sometime during their development, although its not necessarily seen when the animal is adult. In many animals its a vestigial structure
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.
What are the four features of chordates?
Things that are classified into the "Chordata" category in taxonomy have these four features alike: -Dorsal, hollow nerve cord. -Backbone. -Head with eyes and a brain. -Gill slits and a post anal tail sometimes during development. I hope this helped:)
Why is an Elephant in Animalia?
To answer the question in the simplest way, the elephant has a backbone.However, there is more to it than that, especially given that there are two invertebrate chordate groups - Urochordata (tunicates) and Cephalachordata (lancelets) - whose backbone is not in the form of actual vertebrae.As Chordates (or members of the phylum Chordata), elephants share the following characteristics:dorsal nerve cord which is a bundle of nerve fibres which runs down the back. It connects the brain with the lateral muscles and other organs.notochord which is a cartilaginous rod running underneath, and supporting, the nerve cord - in the case of the elephant, a spine.post-anal tail - an extension of the body past the anal opening. (This feature is not always present in some adult Chordates such as frogs and humans, but it is present in the elephant.)Pharyngeal pouches - Chordates, at some stage of their life, have pharyngeal grooves and pouches that develop into other essential parts of their anatomy.
What vertebrate group is a lizard in?
All vertebrates are members of the phylum Chordata, but not all creatures in Chordata are vertebrates. There are three subphylums in Chordata. Two of them are invertebrates - Urochordata (tunicates) and Cephalachordata (lancelets), while the third is Vertebrata (vertebrates). This phylum includes all animals which have a hollow nerve cord and a notochord at some stage during their development. In the case of vertebrates, the notochord is present in the embryo, and develops into the vertebral body. In the tunicates, the adult form no longer has the notochord. Another characteristic they share is that, at some stage during their lives, they have pharyngeal grooves and pouches that develop into other essential parts of their anatomy (many textbooks still state that all vertebrate embryos have gill slits, but there has been a great deal of development in the science of embryology to refute this claim). Chordates all have a post-anal tail, which means an extension of the notochord and nerve chord behind the anus, although this feature is no longer present in the mature forms of some creatures such as frogs, and some mammals such as people. Chordates also have a closed circulatory system, although not all Chordates have an actual heart like the vertebrate Chordates do.
What distinguishes a chordates?
At some point in all chordates' lives, they have a notochord, a nerve chord, gill slits and a tail. Some chordates are more complex though.
Do all chordates have a postanal tail some time in the lives?
yes
What is three things all chordates have in common besides a back bone what do all chordates have in common beside a backbone?
All Chordates have(in part of their life or another) A Notochord A hollow dorsal nerve cord A post-anal tail
What do all choradates have?
all chordates have notochord, gill slits, postanal tail, and nerve chord.
What are the characteristics that all chordates share?
a hollow nerve cord, a notochord, pharyngeal pouches, and a postanal tail
What are 4 things that all chordates have in common?
All Chordates have:1) a notochord2) pharyngeal slits3) a postanal tail4) a hollow dorsal nerve chordRead more: What_are_the_four_characteristics_of_a_chordate
Is a white tail deer chordata?
Yes. As Chordates (or members of the phylum Chordata), deer share the following characteristics:dorsal nerve cord which is a bundle of nerve fibres which runs down the back. It connects the brain with the lateral muscles and other organs.notochord which is a cartilaginous rod running underneath, and supporting, the nerve cord - in the case of the deer, a spine.post-anal tail - an extension of the body past the anal opening. (This feature is not always present in some adult Chordates such as frogs and humans, but it is present in the deer.)Pharyngeal pouches - Chordates, at some stage of their life, have pharyngeal grooves and pouches that develop into other essential parts of their anatomy.
What are the four body parts of all chordates?
Notochord, Postanal Tail, Pharyngeal Slits, Dorsal hollow nerve cord
Is baby born with a tailbone?
Yes, one of the key characteristics of chordates is that they have a post anal tail, including during fetal development.
What are three structures that all chordates have in common?
Chordates are animals that comprise the vertebrates. The three structures that are present during their development are the notochord, a tubular nerve cord and gill slits leading into the pharynx.
What three characteristics do all chordates share?
All chordates have a dorsal, hollow nerve cord, a flexible, rodlike, internal supporting structure called a notochord, and paired gill slits in the throat region at some point in their lives.
Is a whale in the Phylum Chordata?
Yes, whales are chordates. They are also vertebrates, meaning they have a skeletal system.However, there is more to it than that, especially given that there are two invertebrate chordate groups - Urochordata (tunicates) and Cephalachordata (lancelets) - whose backbone is not in the form of actual vertebrae.As Chordates (or members of the phylum Chordata), whales share the following characteristics:dorsal nerve cord which is a bundle of nerve fibres which runs down the back. It connects the brain with the lateral muscles and other organs.notochordwhich is a cartilaginous rod running underneath, and supporting, the nerve cord - in the case of the whale, a spine.post-anal tail - an extension of the body past the anal opening. (This feature is not always present in some adult Chordates such as frogs and humans, but it is present in the whale.)Pharyngeal pouches - Chordates, at some stage of their life, have pharyngeal grooves and pouches that develop into other essential parts of their anatomy.
