- Protostomia | Mollusks, Annelids, Arthropods | Britannica
Protostomia, group of animals—including the arthropods (e g , insects, crabs), mollusks (clams, snails), annelid worms, and some other groups—classified together largely on the basis of embryological development
- Protostome - Wikipedia
Protostomes are divided into the Ecdysozoa (e g arthropods, nematodes) and the Spiralia (e g molluscs, annelids, platyhelminths, and rotifers)
- What Is a Protostome? - Encyclopedia. com
Animals in which the blastopore becomes the mouth are called protostomes; those in which the mouth develops after the anus are called deuterostomes (from the Greek "deutero," meaning second, and "stoma," meaning mouth)
- 11. 3 Protostomes – VCU BIOL 152: Introduction to Biological Sciences II
Protostomes are animals whose blastopore (initiated by gastrulation) becomes the mouth of the future digestive system This is called protostomy or “first mouth ” In protostomy, solid groups of cells split from the endoderm or inner germ layer to form a central mesodermal layer of cells
- Protostome - an overview | ScienceDirect Topics
Two major lines of more complex animals were derived from the coelomates: the protostomes, which became the higher invertebrates, and the deuterostomes, which eventually gave rise to the vertebrates
- (Protostomias) - Marine Life Identification
Protostomias (or Protostomia) is a diverse clade in the animal kingdom that encompasses a variety of invertebrates, including arthropods, mollusks, and annelids
- Why Are Earthworms And Insects Called Protostomes
Common examples of protostomes include insects, snails, and earthworms Protostomes exhibit spiral and determinate cleavage during early embryonic development, and the coelom in protostomes is formed by splitting of the mesodermal mass, known as schizocoely
