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.
Two species belonging to the same class must also belong to the same?
Phylum. Organisms in the same class belong to the same phylum, which is a higher taxonomic rank that groups organisms based on shared characteristics.
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 is protochordata?
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
