Larva
Larva, especially the structure seen during the embryonic development of the lower vertebrates and insects. The developmental stage from the formation of the fertilized egg to the cracking of the chorion membrane. The larvae undergo metamorphosis and become adults. They are especially important forms for fixed animal groups. Corals, lice, some dericidens, overalls, etc. they also spread. The larvae, mostly seen in water and land animals, are simple living organisms that meet their own nutrition. As they are in an era-like structure, the environments in which adults and larvae live are also different. Sometimes, the larval forms of different animals differ in their similar, progressive developments. ▪ Socenters in Planula, Veliger, ▪ Oncospheres, Cystoserkus, ▪ Parasitic butterflies in Miracidium, Sposist, Redi, Serkariya, Metacercaria, ▪ Crocuses and ringworms in Trochophore, ▪ Derisidikenlerde Bipinnaria, Branchiolaria, ▪ Crustaceans in Nauplius, Zoea.
