you can tell the difference between the mouth and anus because the mouth is darker then the anus and the mouth is a little bit larger than the anus
Anus itself is,in a different view, the last ending of the digesting system that works as a valve to hold "dirt" from going out the inner part of the anus MUST be so dirty if you Wash it with a mild soap and water the anus will be clean.
The digestive system, a tube, connects the mouth to the anus.
The alimentary canal runs from the mouth to the anus.
Mouth, pharynx, epiglottis, stomach, small intestine, large intestine
deuterostomes
The mouth is formed second, after the anus.
blastopore
blastopore
blastopore.
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.
No. All animals have one mouth and one anus.
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
All animals except for echinoderms (such as starfish) and chordata (mammals, reptiles, fish and birds), haemichordata (vermiform creatures and chaetognatha (worms with "hairs".).
Its a deuterostome
A planarian has a mouth located in the middle of the underside of their bodies. They don't have anuses.
The anus for a jellyfish is its "mouth".
