What is Schizocelom and enterocoelous
True coelom is categorised into two types- schizocoelom and enterocoelom. They are categorised based on ways in which true body cavity or coelom arises in different animals. Schizocoelom arises from mesoderemal split. This body cavity is formed from blocks of mesoderm around the gut that enlarge and hollow out. All the schizocoelomates are protostomains.It's cleavage is holoblastic,spiral and determinate. . Example- animals belonging to the Phyla Annelida, Mollusca and Arthropoda.
Enterocoelom arises from outpocketing of the embryonic gut(endoderm). This type of body cavity is formed by outpocketings of the primitive gut that break off and form the coelom. All the enterocoelomates are deuterostomes. Cleavage is radial and indeterminate . Example- animals belonging to the Phyla Echinodermata , Hemichordates and Chordata.
