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:)
What phylum have true coelom and are deuterostomes?
The phylum that have a true coelom and are deuterostomes are the phylum Chordata. This phylum includes animals with a notochord, dorsal nerve cord, pharyngeal slits, and post-anal tail at some stage in their development. Examples of Chordata include vertebrates such as fish, amphibians, reptiles, birds, and mammals.
What kingdom do echinoderms belong to?
Echinoderms are kept under kingdom: Animalia
In what ways are tunicates and lancelts similar to humans?
Tunicates and lancelets are common to humans in that all of them are chordates. That is they share certain charcteristics at some point in their lives. Four traits that they all share are notochord, hollow dorsal nerve chord, post anal tail, and pharyngeal gill slits. Some of these characteristics disappear during development, others are retained.
Is a post-anal tail a vertebrate?
A post-anal tail is not a vertebrate itself; rather, it is a feature found in certain vertebrates, including all chordates during some stage of their development. This tail extends beyond the anus and is characteristic of the embryonic stages of vertebrates like mammals, birds, and fish. In some species, the post-anal tail is retained into adulthood, while in others, it is lost during development. Thus, while vertebrates can possess a post-anal tail, the tail itself is not classified as a vertebrate.
Why does a cat belong to phylum Chordata?

What chordate groups lacks a post-anal tail and a notochord as adults?

What is a post anal tail?
It is found in chordates and it is a continued version of the anal and is used for locomotion - it helps the organism to move easily in water.

Are perch in the phylum chordate?
Yes. Perch are in the Phylum Chordata as they exhibit the four major characteristics of a chordate: a notochord, pharyngeal gill slits, a hollow dorsal nerve cord, as well as a post anal tail.
What are the four body parts of all chordates?
Notochord, Postanal Tail, Pharyngeal Slits, Dorsal hollow nerve cord
What is the body plan of an invertebrate Chordate?
The body plan of an invertebrate Chordate is quite unique as it does not entail a backbone. It has a hollow dorsal nerve cord and post-anal tail among other crucial features.
