Introduction to the Deuterostomia [2]
The Deuterostomia comprise one of the major groups within the animal kingdom, and it is probably the most familiar to you, since you are a deuterostome! Most of the deuterostomes belong to one of two groups that include the majority of its members — the echinoderms (the spiny skinned starfish, sea urchins, and their relatives) and the chordates (which include fish and other vertebrates). It may be surprising to some that chorates and echinoderms are related — most people do not feel close kinship with sea urchins and sea cucumbers — but both groups share a number of important morphological and developmental features.
Obviously this is not true for adult echinoderms like starfish, and you may wonder what radially symmetric critters are doing in this group. If you were to watch an embryonic starfish develop, you would see that it begins life bilaterally, but switches to radial symmetry as it matures.
To understand this feature, a little animal embryology is necessary. In the earliest stages of embryo development, when there are only a few cells and the embryo resembles a tiny globe of cells, a small pucker develops on one side of the embryo
Deuterostome [3]
‘second mouth’ in Greek)[2][3] are animals typically characterized by their anus forming before their mouth during embryonic development. The group’s sister clade is Protostomia, animals whose digestive tract development is more varied
In deuterostomy, the developing embryo’s first opening (the blastopore) becomes the anus, while the mouth is formed at a different site later on. This was initially the group’s distinguishing characteristic, but deuterostomy has since been discovered among protostomes as well.[4] This group is also known as enterocoelomates, because their coelom develops through enterocoely.
Together with Protostomia and their out-group Xenacoelomorpha, these compose the Bilateria, animals with bilateral symmetry and three germ layers.. Initially, Deuterostomia included the phyla Brachiopoda,[5] Bryozoa,[6] Chaetognatha,[7] and Phoronida[5] based on morphological and embryological characteristics

15.5: Echinoderms and Chordates [5]
Deuterostomes include the phyla Echinodermata and Chordata (which includes the vertebrates) and two smaller phyla. Deuterostomes share similar patterns of early development.
The phylum includes about 7,0001 described living species, such as sea stars, sea cucumbers, sea urchins, sand dollars, and brittle stars. Adult echinoderms exhibit pentaradial symmetry and have a calcareous endoskeleton made of ossicles (Figure \(\PageIndex{1}\)), although the early larval stages of all echinoderms have bilateral symmetry
These animals have a true coelom, a portion of which is modified into a unique circulatory system called a water vascular system. An interesting feature of these animals is their power to regenerate, even when over 75 percent of their body mass is lost.
Biology, Biological Diversity, Vertebrates, Chordates [6]
Vertebrates are members of the kingdom Animalia and the phylum Chordata (Figure). Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development
Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.
In some groups, some of these are present only during embryonic development.. The chordates are named for the notochord, which is a flexible, rod-shaped structure that is found in the embryonic stage of all chordates and in the adult stage of some chordate species
Nodal signaling and the evolution of deuterostome gastrulation [7]
Nodal signaling and the evolution of deuterostome gastrulation. Nodal signaling and the evolution of deuterostome gastrulation
All holoblastic deuterostomes gastrulate at the vegetal pole and the blastopore becomes the anus, while a mouth is formed at the anterior or to the oral side. Nodal is a member of the TGF-beta superfamily of signaling molecules that are important in signaling between cells during many embryonic processes in vertebrate embryos
Nodal has been shown to be particularly important in determining left-right asymmetries in vertebrate embryos, but less information is available for its developmental role in the invertebrate deuterostomes. We review gastrulation in the deuterostomes, then examine nodal expression early during mesoderm formation and later during the establishment of asymmetries in both vertebrates and invertebrates

The word deuterostome comes from the Greek word meaning “mouth second,” indicating that the anus is the first to develop. There are a series of other developmental characteristics that differ between protostomes and deuterostomes, including the mode of formation of the coelom and the early cell division of the embryo

Recent molecular phylogenetic studies suggest that the deuterostomes include only the echinoderms, hemichordates, and chordates. Among the echinoderms, sea urchins are most widely used for developmental studies
Although sexual reproduction is predominant, reproduction by asexual budding occurs in a number of groups that have colonial forms, including pterobranch hemichordates and the colonial ascidians. Experimental work with invertebrate deuterostomes has played an important role in developmental biology, cell biology, and genetics
Difference Between Protostomes and Deuterostomes [10]
The animal kingdom is diverse in terms of morphology, anatomy, and physiology. Despite the differences, one thing that remains common among most animals is that they all start life as a single cell
One such group of animals are called the metazoans whose body cells are differentiated into tissues and organs. Based on the embryonic development of these metazoans, they are classified into two groups – protostomia and deuterostomia (or protostomes and deuterostomes).
The reason for this naming is based on their mode of embryonic development. When the embryo develops, the protostomes first form the mouth from the blastopore, and the anus develops later after the mouth has been created.

Invertebrate deuterostomes, which include echinoderms (e.g., sea urchins, starfish, and sea cucumbers) hemichordates (e.g., acorn worms), cephalochordates (e.g., amphioxus), and urochordates (e.g., ascidians), occupy an “intermediate” phylogenetic position with respect to vertebrates and protostomes (e.g., arthropods, nematodes, annelids, mollusks). Therefore, these animals are important model organisms in the fields of evolutionary biology, developmental biology, comparative physiology, and comparative genomics.
Difference Between Protostomes and Deuterostomes [12]
Based on the embryonic development, metazoans are divided into protostomes and deuterostomes. Protostomes are primitive invertebrates while deuterostomes include chordates and echinoderms
The main difference between protostomes and deuterostomes is that the blastopore in protostomes are developed into a mouth while the blastopore in deuterostomes is developed into an anal opening. Given below in a tabular column are the differences between protostomes and deuterostomes.

Altering levels of endogenous RA signaling during early embryology leads to severe malformations, mainly due to incorrect positional codes specifying the embryonic anteroposterior body axis. In this review, we present our current understanding of the RA signaling pathway and its roles during chordate development
We find that some of the control mechanisms governing RA-mediated patterning are well conserved between vertebrates and invertebrate chordates, such as the cephalochordate amphioxus. In contrast, outside the chordates, evidence for roles of RA signaling is scarce and the evolutionary origin of the RA pathway itself thus remains elusive
Biology 2e, Biological Diversity, Vertebrates, Chordates [14]
Vertebrates are members of the kingdom Animalia and the phylum Chordata (Figure). Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development
Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.
In some groups, some of these key chacteristics are present only during embryonic development.. The chordates are named for the notochord, which is a flexible, rod-shaped mesodermal structure that is found in the embryonic stage of all chordates and in the adult stage of some chordate species
