A. Genus Two characters Class/phylum Salamandra (i) A tympanum represents ear (ii) Fertilization is external Amph
Step-by-step solution
Pteropus (flying foxes) belongs to Class Mammalia. The only platypus is an egg-laying mammal and thus flying foxes are viviparous. Aurelia is a jellyfish. These belong to Phylum Coelenterata. These are also known as Cnidaria due to the presence of Cnidoblast stinging cells. This phylum shows the tissue level of organization. Ascaris belongs to Phylum Aschelminthes and these are hermaphrodites. Salamanders are tailed amphibians. These lack external ears and fertilization is external.
