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.
What do all choradates have?
all chordates have notochord, gill slits, postanal tail, and nerve chord.
Is ventral nerve chord non chordate character?
Yes, the ventral nerve cord is a character found in chordates, not non-chordates. It is a defining feature of chordates, running along the belly side of the body and often involved in coordinating motor functions.
Do dugongs have nerve cords?
Yes. Being a vertebrate in the animal kingdom, all chordates have a "hollow dorsal nerve chord'' aka vertebral column or spine or backbone.
Is an earthworm a chordate?
Yes, all chordates have a nerve chord running down their back and an earthworm has a nerve chord running down it's back therefore it is a chordate
What is chordates?
Chordates are the family of organisms that have a spinal column which supports their body structure. A chordate's nerve chord is the organ contained and protected by the spinal bones. The nerve chord is what transmits signals to and from the brain.
Are chordates a central solid nerve cord?
Yes, chordate's nerve cord is hollow as opposed to animals that are non chordate with a nerve cord which are solid.
The elaboration of a notochord and a dorsal nerve chord the key developmental event that marks the evolution of the chordates is referred to as?
The elaboration of a notochord and a dorsal nerve chord the key developmental event that marks the evolution of the chordates is referred to as neurulation. The hollow crater formed during gastrulation is known as the archenteron.
What animals have a tubular nerve cord and gill slits at some point in their lives?
No, not all vertebrates have tubular nerve cord.
What characteristics does the Arizona black rattlesnake have to make it part of the chordata phylum?
It has a nerve chord running down its back, the defining trait of all chordates.
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.

What is the common name for chordates?
Chordate is the common name for a very large group of animals (kingdom Animalia) that, at some stage in their life cycle, have something resembling a spinal chord or column, and gill slits. The phylum is called Chordata, and includes humans (we have gill slits in our fetal stage.
