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 phyla of animals have a segmented body plan?
Animals with a segmented body plan belong to the phyla Arthropoda, Annelida, and Chordata. Segmentation involves the repetition of body units along the length of the organism, which can be seen in arthropods with their jointed limbs, annelids with their repeated segments, and chordates during embryonic development.
Animals are classified according to body plan as?
Animals are classified according to body plan as symmetrical or asymmetrical. Symmetrical animals are usually bilateral (two-sided) or radial (multiple planes of symmetry), while asymmetrical animals have no defined body plan. These classifications help scientists understand the evolutionary relationships between different groups of animals.
What is the grouping of animals into phyla based on?
no idea what the anwser is
What is vertebrate zoology?
Within the Animal Kingdom there are many phyla, or categories of animals. One such category is chordata. All chordates have, at some time in their development, a notochord. For some animals this notocord later develops into a spinal column Vertebrates are members of the subphylum vertebrata: chordates with backbones or spinal columns. Vertebrate zoology is the study of non-human vertebrates.
Does a sea sponge has radial symmetry?
No Animals display different kinds of symmetry. The Radiata include radially symmetrical Ctenophora and Cnidaria (previously Coelenterata). Echinodermata are also largely radially symmetrical. Many other phyla, such as all worm phyla are termed bilaterally symmetrical. Sponges (Porifera) are very primitive and display neither of these types of symmetry. In fact they are usually very irregular and asymmetrical in shape.
What is non chordata?
Non-chordata is a zoological group that includes all animals excluding the chordates. These animals lack a notochord or backbone, which is a defining feature of chordates. Non-chordates belong to diverse phyla such as Arthropoda, Mollusca, and Annelida.
What phylums are the horses in?
Phyla Chordates, they are vertebrates.
On what basis do taxonomists group animals into phyla?
1.Level of organisation-Either cellular level,tissue level or organ level. 2.Symmetry-Whether the organism is asymmetrical,bilaterally symmetrical or radially symmetrical. 3.Whether the Organism is Diploblastic or Triploblastic. 4.Presence of coelom-acoelomate,pseudocoelomate or acoelomate. 5.Presence of Notocord-Absent, Present for some time in life cycle or present throughout life cycle.
Kingdom of organisms that have characteristics from the other phyla?
The kingdom of organisms that exhibit characteristics from various phyla is the kingdom Animalia. Animals encompass a wide range of phyla with diverse characteristics, such as chordates, arthropods, and mollusks, among others. This diversity is a key feature of the animal kingdom.
Are humans part of the chordates section of the animal phyla?
yes we are! Because we have a backbone.
What are 3 ideas regarding the evolutionary position of the radiate phyla?
The radiate phyla are considered to be primitive invertebrates that diverged early in evolution, before the emergence of more complex phyla such as the chordates. They exhibit radial symmetry, distinguishing them from bilaterally symmetrical animals, suggesting an evolutionary divergence from a common ancestor that gave rise to both radial and bilateral symmetry. Their simple body plans and lack of specialized organs indicate an early evolutionary divergence, suggesting they represent an ancient lineage with limited evolutionary changes over time.

Give an example of asymmetrical animals?
Butterflies. Many animals are more or less symmetrical, with exceptions like crabs and lobsters which have one much larger claw, and some animals like flatfish which have evolved from a symmetrical ancestor in such a way as to favour one side only. Among humans, asymmetrical bodies or features are perceived as uglier, or as deformed, so there may be strong selection pressures to choose a more symmetrical mate. Animals which are super-symmetrical include peacocks, butterflies and patterned mammals such as tigers, leopards and ocelots. The last three are particularly symmetrical in their facial markings, which suggests that it gives a selection advantage.
Do arthropod have coelom?
Yes, phylum Arthropoda is classified as coelomate along with about half of all known phyla, including molluscs, annelids, and chordates.
What are the three kinds of chordates?
Phylum chordata is divided into three sub-phyla: 1) Urochordata or Tunicata 2) Cephalochordata 3) Vertebrata
