Axolotl larva belongs to the order
A. Urodela
B. Anura
C. Apoda
D. Stegocephalia

Answer 1

Hint:Axolotl refers to a group of animals, which can live both on land and in water, Neoteny, a peculiar phase, exhibits Axolotl, in which the adult organism retains some of its larval characteristics and it is not lost until it reaches maturity.

Complete answer:
Axolotl is known as Larva Ambystoma or Tiger Salamander. It has three pairs of outer gills and a caudal fin that bears the tail. Caudal fins are assisting with the swimming process. They belong to the order of the Urodela class of the Amphibians. Urodela is the order of the amphibians that are tailed. They have been characterized by the IUCN as fundamentally (critically) endangered species. Although they are the top predators in their lake climate, this has not been the case recently. The introduction of large fish into the lake, followed by the drainage and depletion of the lake, has decreased their population. They were also used in food menus in Mexico, so they were captured by the fishermen.
Some of Axolotl's ideal characteristics are:
It exhibits sexual dimorphism where it is possible to distinguish between males and females externally. There is a wider cloaca, a longer tail, and a narrow head in the male. There are narrow cloaks and plump bodies for females.
The surface area for gas exchange is extended by fimbriae or fine filaments around the outer gills.
They are endowed with regenerative capacity.
This involves the recurrence of any detached or damaged appendages for a period of months.

Hence, option A- Urodela is the correct answer.

Note: Amphioxus is a member of the Cephalochordata subphylum, where the notochord persists throughout the life of the organism. It extends over the length of an individual's body. The anterior and posterior ends are both pointed and are thus commonly referred to as lancelets. The members of the Phylum Aschelminthes are Roundworms. The syncytial epidermis is a non-segmented pseudocoelom, i.e., the epidermis is a continuous long layer with several scattered nuclei. E.g., Ascaris. -Silkworms or Bombyx mori are insects commonly cultivated in their silk fiber cocoon.
