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".

What is systematic position of protochordata?
Protochordata is a subphylum within the phylum Chordata. It includes three groups: Hemichordata, Urochordata (Tunicata), and Cephalochordata. These organisms exhibit some characteristics of chordates, such as a notochord and dorsal hollow nerve cord, but lack some of the defining features found in more advanced chordates like vertebrates.
What characteristics do Hemichordata share with Echinodermata?
No cephalization Radial symmetry All are Deutorosomes. Another 3, that are better, and more common, are: 1. Entirely marine 2. Water vascular system 3. Spiny skin, which is what Echinoderm means
What animals have a true coelom?
Depending upon the coelom, the animals are divided into1)Acoelomates - Eg: Platyhelminthes2)Pseudocoelomates Eg: Nematyhelminthes3)Eucoelomates: - Eucoelomates are further divided into two typesa) Schizocoelom -Eg: Annelida, Arthropoda, Molluscab) Enterocoelom -Eg: Hemichordata and Chordata

Is hemichordata same as protochordata?
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.

What is the scientific name of acorn worm?
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.
What are the examples of phylum hemichordata?
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.

What symmetry are the 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.
What are the general characters of hemichordata?
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
What are the three other groups of vertebrae animals?
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

What are the Classification of invertebrates?
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)
