both have a nerve cord
What else can I help you with?
Do chordates and echinoderms have a common ancestor?
yes
Are Chordates and echinoderms are both protostomes?
Neither are protostomes. Chordates, Hemichordates, and Echinoderms are all deuterostomes (in that the blastopore forms the anus first). In protostomes, the blastopore forms the mouth first.
What are echinoderms considered to be closely related to chordates?
both have deuterostome development...(:
Why are Echinoderms considered to be closely relate to chordates?
both have a nerve cord
how do lower chordates survive on their adaptive features?
echinoderms, cnidaria and other forms
Why are Echinoderms classified into phylum Chordata?
Echinoderms are not classified in phylum Chordata. They belong to their own phylum called Echinodermata. Chordates, on the other hand, are characterized by the presence of a notochord, which echinoderms lack.
What phylum your invertebrate specimen belong to?
Echinoderms are marine animals that are invertebrates, while Chordates are animals with backbones. Hope this helps!
Does echinoderms have a close evolutionary relationship with chordates?
Yes they do. Echinoderms, which include starfish, and chordates, which include humans are closely related in an evolutionary sense due to the way their embryos are formed in the early stages of development. Once past that point, the very obvious differences form.
Why are echinoderms closely related to chordates?
most chordates are vertebrates, but some are not. invertebrate chordates belong to two of the subphylum of chordates. Cephalochordata and Urochordata. both invertebrate and vertebrate chordata have a dorsal nerve cord, a notochord, pharyngeal pouches and a postanal tail.
Why are starfish considered to be most similar to the chordates?
because
How is the embryology of echinoderms similar to vertebrates?
Echinoderms such as starfish and similar marine animals with radially symmetrical bodies have bone-like calcareous skeletal plates in their skin
Why are echinoderms considered to be closely related to corroded?
Echinoderms, such as starfish and sea urchins, are considered closely related to chordates, including corals, due to their shared evolutionary lineage within the deuterostomes, a major group of animals characterized by specific developmental features. Both echinoderms and chordates exhibit bilateral symmetry at some stage of their development and share common genetic and embryological characteristics. Moreover, molecular studies have shown significant genetic similarities between these groups, supporting their close evolutionary relationship.
