What is the different between the Protostomia and Deuterostomia give an example?
Complex and higher organisms like humans, other terrestrial animals like tigers, monkeys, etc. are examples of deuterostomes. Simpler and lower organisms like Arthropods, Flatworms, Annelids, etc. are examples of protostomes.
What are deuterostomes examples?
What is a Protostome and Deuterostome?
Based on the embryonic development, metazoans are divided into protostomes and deuterostomes. Protostomes are primitive invertebrates while deuterostomes include chordates and echinoderms. This division is helpful in understanding the relationships between different groups of animals.
What is Deuterostomia in biology?
Definition of deuterostome
: any of a major division (Deuterostomia) of the animal kingdom that includes the bilaterally symmetrical animals (such as the chordates) with indeterminate cleavage and a mouth that does not arise from the blastopore.
What does Protostomia mean?
Pro·to·sto·mia. : animals in which the definitive mouth develops directly from the blastopore (as most worms, bryozoans, brachiopods, mollusks, and arthropods) compare deuterostomia.
What makes something a protostome?
A protostome is a type of animal that has spiral determinate cleavage, a mouth that develops before the anus in embryos, true tissues, and is bilaterally symmetric. Protostomes are classified using their similar internal body plans. Humans are not protostomes because their anus develops before the mouth.
What defines a protostome?
protostome in American English
(ˈproutəˌstoum) noun. Zoology. any member of the lower invertebrate phyla in which the mouth appears before the anus during development, cleavage is spiral and determinate, and the coelom forms as a splitting of the mesoderm.
Are humans a protostome?
Humans are deuterostomes, which means when we develop from an embryo our anus forms before any other opening.
Are humans protostomes?
Thus, humans are deuterostomes.
Is an ant a protostome?
A few examples of the protostomes are an octopus, squid, spiders, ants, bees, oysters, etc.

Is a Butterfly a protostome?
Butterflies (Arthropoda) are protostomes. Bats (Vertebrata) are deuterostomes.

Are spiders protostomes?
Some of the most common protostomes are flatworms (such as tapeworms), nematodes (such as heartworms), mollusks (such as snails and slugs), annelids (such as earthworms), and arthropods (spiders, insects, lobsters, ticks, barnacles, and more!). Some of these groups are more diverse than others.
