What is the meaning of Chordata phylum?
Introduction to Phylum Chordata. The phylum Chordata consists of animals with a flexible rod supporting their dorsal or back sides. The phylum name derives from the Greek root word chord- meaning string. Most species within the phylum Chordata are vertebrates, or animals with backbones (subphylum Vertebrata).
What is the meaning of the word Arthropoda?
Definition of arthropod : any of a phylum (Arthropoda) of invertebrate animals (such as insects, arachnids, and crustaceans) that have a segmented body and jointed appendages, a usually chitinous exoskeleton molted at intervals, and a dorsal anterior brain connected to a ventral chain of ganglia.
What organisms are in the phylum Chordata?
Chordata contains five classes of animals: fish, amphibians, reptiles, birds, and mammals; these classes are separated by whether or not they can regulate their body temperature, the manner by which they consume oxygen, and their method of reproduction.
What are the fundamental characters of phylum Chordata?
Phylum Chordata possesses the following characteristic features:
- Notochord. It is a longitudinal, cartilaginous rod running between the nerve cord and the digestive tract.
- Dorsal Nerve Cord.
- Pharyngeal Slits.
- Post anal Tail.
- Urochordata.
- Cephalochordata.
- Vertebrata.
- Lampreys.
What are the members of phylum Chordata?
1 Answer. Chordata is a familiar phylum that includes organisms like mammals, fish, birds, reptiles, and amphibians (all vertebrates); sea squirts (tunicates); and lancelets (cephalochordates). All chordates have a notochord, a dorsal nerve cord, and pharyngeal slits at some point in their development.
Which is the second largest phylum?
Mollusca
Mollusca is the second largest phylum in the animal kingdom.
Which phylum is most closely related to Chordata?
Why are echinoderms more closely related to chordates? Echinoderms are the most closely related phylum to the phylum Chordata, which includes many complex organisms such as humans. Their shared common ancestor was likely a bilaterally symmetrical organism with a cephalized (centralized in a head region) nervous system.
What are the common characteristics of the phylum chordates?
Pharyngeal pouches and pharyngeal gill slits
