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.
Do pharyngeal slits disappear before birth in all chordates?
No, pharyngeal slits do not disappear before birth in all chordates. In some chordates, such as fish, these slits persist throughout their life and play a role in respiration and feeding. In other chordates, such as mammals, the pharyngeal slits do not persist through adulthood but are present during embryonic development.
Do all chordates have fins?
Not all chordates have fins. While many aquatic chordates, such as fish, possess fins for swimming, other groups, like mammals (including humans) and birds, do not have fins. Instead, these animals have evolved different structures for locomotion, such as limbs for walking or wings for flying. Thus, fins are characteristic of certain chordate lineages but not a universal feature of all chordates.
Where can chordates be found?
First off, a Chordate is anything with a Notochord, aka, a spinal column. So, of course, all vertebrae are Chordates. But also nearly any animal that has an endoskeleton, be it bony or cartilaginous. So sharks are also chordates as are most fish.
Which type of animals are close to chordates from evolutionary point of view?
Chordates are the common ancestors of fish and sharks. They include lampreys and other types of primitive fish species that live in the sea.
What is the popular name for chordates?
There isn't a "popular name" for them. The most familiar chordates are the vertebrates, but not all chordates are vertebrates (tunicates, for example, are chordates).
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
What is a characteristic shared by all chordates the phylum in which humans are classified?
All chordates are deuterostomes, meaning that in all chordates, the anus develops first during embryological development. All chordates are bilaterally symmetric. Most chordates have a complete digestive tract, and a body cavity. Note: not all chordates have these features, but it is believed that their absence in some chordates is secondary. All chordates are of course animals and eukaryotes.
Is not a characteristic shared by all chordates the phylum in which humans are classified?
Yes, all chordates share the presence of a notochord at some stage in their development. However, the phylum Chordata is not specific to humans; it includes a diverse group of animals like fish, birds, reptiles, and mammals.
How are invertebrate chordates such as lancelets different from vertebrates such as fish and mammals?
They don't have a backbone
What do all Chordates have?
a backbone
Do all chordates have jaws and limbs?
Well, no they don't... There's a group of chordates called Agnatha which basically contains all the jawless chordates. And there are obviously limbless chordates present, the fishes and the snakes being the most well-known of the examples...
