the difference is that a duetrostome (second mouth) is the end and the protostome(first mouth) is the begining.
Coelomates that develop with the blastopore becoming the mouth are protostomes. An example of a protostome would be the Caribbean reef squid.
deuterostomes
protosome
Yes, annelids belong to the protostome group of animals. Protostomes are a group of animals whose blastopore develops into the mouth first during embryonic development. Annelids, such as earthworms and leeches, exhibit characteristics consistent with protostome development.
An example of a protostome is a snail. Protostomes are organisms in which the blastopore, the opening of the developing embryo, becomes the mouth of the adult organism.
The plural of perch, when referring to a bird's perch, is perches. The plural of perch, when referring to the fish, remains perch.
protostome development
Deuterostome and protostome are two different ways in which animals develop. In deuterostome development, the first opening that forms becomes the anus, while in protostome development, the first opening becomes the mouth. This difference in the formation of the digestive tract is a key distinction between the two processes.
There are three species of the perch: Percaflavescens (Yellow perch), Perca fluviatilis(European perch) and Perca schrenkii (Balkhash perch).
