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.

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".

irum mustafa is hemichordate and kiran is urochordate SIMPLE

Hemichordata is a phylum of marine deuterostome animals, generally considered the sister group of the echinoderms.

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.
