why can we say that echinodermata and Hemichordata are correlated
Answers
Answer:
Their significant resemblance is their larval stage. Echinoderm larva is a bilateral in shape which is similar to the larval stage of hemichordates. They also have similarities in the arrangement of their coelomic cavities and early embryogenesis.
The echinodermata and hemichordata are known as the sister groups as they share the same features in two phyla.
Explanation:
They both have the bilateral larval stage. Echonodernata and hemichordate larva also have the similarities between the arrangement in their coelomic cavities and the early embryogenesis. The organisms of these chordates have no notochord. Their basic similarities present in their larval statge.
But there are some differences present which can separate them to different phyla.
