What is the animal which are chordates and craniates but not vertabrate?
Myxini (hagfishes) are chordates and craniates. they have a cartillagenous skull but no vertebra or jaws.
A few characteristics of the turtle are listed below Segmented body Jaws and limbs No hair No placenta used during reproduction Where does the turtle belong in the cladogram shown below?
E, limbs (apex)
What happened during evolution that led to the appearance of jaws and skulls in chordates?
The appearance of jaws and skulls in chordates is attributed to evolutionary advancements in early vertebrates, specifically the development of cartilaginous structures that provided support and protection. These features emerged from modifications of the pharyngeal arches, which initially served a respiratory function. Over time, natural selection favored individuals with stronger, more effective jaws for improved feeding strategies, leading to the diversification of vertebrate species. This evolutionary transition marked a significant step in the complexity and adaptability of chordates.
Do chordates have a coelom?
Yes, chordates typically have a coelom. The coelom is a body cavity lined with mesoderm that surrounds the internal organs, providing space for organ movement and protection. It is considered an important characteristic of chordates, although not all chordates have a well-developed coelom.
How are vertebrates and chordates the same?
Vertebrates and chordates share fundamental characteristics, as all vertebrates are a subgroup of chordates. Both groups possess a notochord at some stage of development, a dorsal nerve cord, pharyngeal slits, and a post-anal tail. While chordates include a wider range of organisms such as tunicates and lancelets, vertebrates specifically have a backbone or spinal column, which distinguishes them within the chordate phylum. Thus, all vertebrates are chordates, but not all chordates are vertebrates.
What is the animal which are chordates and craniates but not vertabrate?
Myxini (hagfishes) are chordates and craniates. they have a cartillagenous skull but no vertebra or jaws.
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.
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 does this cladogram tell you about evolutionary relationship of the traits of jaws and limbs?
The cladogram shows that the traits of jaws and limbs have evolved independently in these species. There is no clear correlation between the evolution of jaw traits and limb traits in this specific scenario. This suggests that these traits may have adapted to specific environmental pressures and constraints in a lineage-specific manner.

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 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.
Are all fish chordates?
All fish are chordates. Chordates are vertebrates that have a hollow dorsal nerve called a notochord. They also have a central nervous system and gill clefts.
What do all Chordates have?
a backbone
Do chordates have a coelom?
Yes, chordates typically have a coelom. The coelom is a body cavity lined with mesoderm that surrounds the internal organs, providing space for organ movement and protection. It is considered an important characteristic of chordates, although not all chordates have a well-developed coelom.
What are jaws and limbs characteristics of?
Jaws and limbs are characteristics of vertebrates, particularly within the phylum Chordata. Jaws, derived from modified gill arches, allow for more efficient feeding mechanisms, enabling animals to grasp and process food. Limbs, which may vary in form and function across species, facilitate movement and interaction with the environment, supporting activities such as walking, swimming, or flying. Together, these features contribute significantly to the adaptability and evolutionary success of vertebrate animals.
