At some point in their lives all chordates have what characteristics?

All chordates have a notochord at some stage in their development, even if it is only at the embryonic stage. The notochord is a flexible structure located in front of the dorsal nerve, which all chordates also have.

∙ 13y agoAll chordates share a notochord, dorsal nerve cord, and pharyngeal gill pouches. The notochord, a cartilaginous supporting rod, runs along the dorsal part of the body. It is always found in embryos, but in most vertebrates it is replaced during development by a backbone of bony or cartilaginous vertebrae. The tubular dorsal nerve cord, dorsal to the notochord, is formed during development by an infolding of the ectoderm. In vertebrates the nerve cord eventually becomes encased and thus protected by the backbone. The pharyngeal gill pouches appear during embryonic development on both sides of the throat region, the pharynx.
You missed one:
#1. A supportive anterior to posterior notochord
#2. A dorsal, hollow nerve cord
#3. Pharyngeal gill slits(at some point in their ontongenic development)
#4. A yolk sac(again, at some point in their ontongenic development)

Can chordates not have a notochord and still be what they are?
The presence of a notochord at some point in the organism's development is one of the characteristics that distinguishes chordates from other phyla. Without it, I'm not sure if the organism would be considered a chordate.
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.
Write some characters common to both Chordates and non Chordates?
Notochord
What are chordates and non chordates?
Some of these non-chordates are marine animals. These animals are without a backbone. Some of these animals are... Fish Coral Sea-Aneamone
At some stage of their development all chordates have a supportive rod along their back called the?
Notochord
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.
Can chordates not have a notochord and still be what they are?
The presence of a notochord at some point in the organism's development is one of the characteristics that distinguishes chordates from other phyla. Without it, I'm not sure if the organism would be considered a chordate.
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.
What animals have a tubular nerve cord and gill slits at some point in their lives?
No, not all vertebrates have tubular nerve cord.
Do all chordates have a postanal tail some time in the lives?
yes

Are lancelets not true chordates?
They are actually true chordates, however they are some of the simplest chordates.
Is chordates vertebrates?
Chordates are not vertebrates because although some vertebrates are chordates theres many reasons why chordates arent vertebrates.the first reason is because chordates consist of a notochord or a dorsal nerve.
What some chordates such as sea squirts and lancelets do not have?
Chordates such as the sea squirts and lancelets do not have a backbone that is why they are called vertebrate chordates.
Write some characters common to both Chordates and non Chordates?
Notochord
All vertebrates are chordates but not all chordates are vertebrates?
all vertebrates are chordates because vertebrates are the sub- group of phylum chordates and also it follow one of the important feature of the chordates i.e. presence of notochord whereas all chordates are not vertebrates because some chordates are cephalochordates, urochordates.
What are chordates and non chordates?
Some of these non-chordates are marine animals. These animals are without a backbone. Some of these animals are... Fish Coral Sea-Aneamone
