Coelomates that develop with the blastopore becoming the mouth are protostomes. An example of a protostome would be the Caribbean reef squid.

Does the blastopore forms a mouth?
In protostome ("first mouth") the blastopore, or the first opening formed becomes the mouth. In deuterostomes ("second mouth"), the blastopore forms the anus and the mouth develops from a second opening.
Among coelomates in which of these does development occur by radial cleavage and the anus forms before the mouth?
Protostomes
What is the organism whose blastopore becomes an anus?
All animals except for echinoderms (such as starfish) and chordata (mammals, reptiles, fish and birds), haemichordata (vermiform creatures and chaetognatha (worms with "hairs".).
What is the difference between protosome and deuterosome?
Protostomes Deuterostomes 1.Mouth develops first then anus 1. Anus develops first then mouth 2.Blastopore develops into mouth 2.Blastopore develops into anus 3.Coelom absent and a schizocoel 3. Coelom develops as enterocoel by fusion develops by a split of mesoderm of gut pouches. 4.Cleavage is spiral and determinate 4. Cleavage is radial and indeterminate. 5.Larva is trochophore. 5. Larva is bipinnaria or tornaria 6.E.g. Molluscs, annelida & 6.E.g. Echinodermata & Chordata arthropodes
Why don't mayflys have mouths?
The nymph form of the mayfly does have a mouth. It feeds on plant material. The adult does not have a mouth because they mate right away and die within 3 days of becoming an adult. they do not eat as adults
Does the blastopore forms a mouth?
In protostome ("first mouth") the blastopore, or the first opening formed becomes the mouth. In deuterostomes ("second mouth"), the blastopore forms the anus and the mouth develops from a second opening.
What does the blastopore become?
At the stage of development when the gut forms there is only a single opening into the digestive track, this opening may become either the mouth or anus. In the echinoderms, chordates, and hemichordates the blastopore becomes the anus and a new opening forms the mouth, these are called deuterostomes
What is the animal if the blastopore develops into a mouth?
protostomes:)
The structure that is found in an opening to the central cavity and develops into a mouth or an anus in the organism is called the?
blastopore.
How is a blastopore used to indicate evolutionary relationships?
The blastopore is an indentation that forms during early embryonic development. Its fate can differ between species, with some having the blastopore develop into the mouth (protostomes) and others into the anus (deuterostomes). This distinction is used to infer evolutionary relationships between organisms, as species that share similar blastopore fates are considered more closely related.
What is deuterostome development?
The mouth is formed second, after the anus.
What is the structure that is found in an opening to the central cavity and develops into a mouth or an anus in the organism?
blastopore
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.
The structure that is found in an opening to the central cavity and develops into a mouth or an anus in the organism is called?
blastopore
Among coelomates which of these develops by spiral cleavage and the mouth forms before the anus?
deuterostomes
Among coelomates in which of these does development occur by radial cleavage and the anus forms before the mouth?
Protostomes
What does proto and deutero?
Protostome means the blastopore becomes the mouth during embryonic development, and deuterostome, the anus. We're deuterostomes.
