No Hemichordata is a separate phylum , but related to Chordata , Protochordates are part of chordates
No, hemichordata and protochordata are not the same. Hemichordata is a phylum of marine deuterostome animals, while Protochordata is a subphylum of chordates that includes organisms like tunicates and lancelets. Both groups are primitive chordates but belong to different taxonomic classifications.
Examples of Protochordata include Lancelets (Cephalochordata) and Tunicates (Urochordata). These organisms are marine chordates that exhibit characteristics of both invertebrates and vertebrates.
Examples of phylum Hemichordata include acorn worms (enteropneusts) and pterobranchs. These are marine organisms that exhibit characteristics of both invertebrates and chordates. Hemichordates play a crucial role in marine ecosystems, contributing to sediment processing and nutrient cycling.
depends on which species you are talking about - there are about 30 different "species" of Acorn worm and all are under the class hemichordata. -one of these Acorn worm is the Balanoglossus sp., the common representative organism under phylum hemichordata.
Adult Hemichordates exhibit bilateral symmetry, meaning their bodies can be divided into two similar halves along a single plane. However, during their larval stage, some species of Hemichordates show a form of metameric or radial symmetry.
Phylum. Organisms in the same class belong to the same phylum, which is a higher taxonomic rank that groups organisms based on shared characteristics.
same as protochordata ----------------------------------------------------------------------------------------- The hemichordata are a a small phylum of marine invertebrates that have a vertebrate like hollow nerve cord and an echinoderm like larval stage. The "hemi" prefix means "half".

The notochord is a characteristic of the 9th & 10th division of the kingdom animalia ,i.e., Protochordata and Vertebra
irum mustafa is hemichordate and kiran is urochordate SIMPLE

1 . The animals are bilaterallysymmetrical , triploblastic and have coelem .2 . They have a notochord , at least some stages during their lives . The notochord run along the back of the animal separating the nervous tissue from the gut . It provides support and a place for muscles to attach .3 . Protochordates are marine animals . Examples are Balanglossus , Herdemania , Amphioxus , etc
Characteristics of Hemichordata:-1)Bilaterally symmetrical.2)Body has more than two cell layers, tissues and organs.3)Body cavity a true coelom.4)Body possesses a through gut, straight or U-shaped, with an anus.5)Body divided into three sections, a proboscis, a collar and a trunk.6)Nervous system normally diffuse, but variable.7)Has a partially open circulatory system.8)Possesses glomerulus as an excretory organ.9)Reproduction normally sexual and gonochoristic.10)Feeds on fine particles in the water.11)All live marine environmentshttp://www.earthlife.net/inverts/hemichordata.html
In phylum Chordata there are 4 sub phylums. 1.Vertebrata 2.Hemichordata 3.Urochordata 4.Cephalochordata Vertebrata consist of 6 classes. 1.Chondrichthyes 2.Osteichthyes 3.Amphibia 4.Reptilia 5.Aves 6.Mammalia
They can be divided into essentially nine subdividions (phyla): -Porifera -Cnidaria -Platyhelminthes -Nematoda -Annelida -Mollusca -Arthropoda -Echinoderma -Chordata (most chordates are those with backbones, so they are usually vertebrates, but some are invertebrates)
