Amphibian Groups Flashcards
Amphibians
Cold-blooded tetrapods.
Most produce eggs that hatch into larvae then metamorphose into adults.
Their porous and glandular skin is kept moist.
Gymnophiona
Caecilians
Limbless, worm like amphibians that burrow in the soil or live in rivers.
Some species lay eggs, producing larvae; others give birth to live young.
Batrachia
Salamanders and Frogs
All Amphibians other than the limbless caecilians. This group includes all types of newts and salamanders and frogs and toads.
Caudata
Salamanders and Newts
Amphibians with elongated bodies, short legs and long tails.
Fertilization is mostly internal and most lay eggs, but some give birth to larvae or small adults
Cryptobranchian
Salamanders with external fertilization.
This group includes giant salamanders and a group of primitive Asiatic salamanders.
Diadectosalamandroidei
Salamanders with internal fertilization carried out using a spermatophore (sperm capsule) that is transferred from the male into the female.
Treptobranchians
Salamanders that as larvae are aquatic with external gills, and as adults are terrestrial and breath using lungs.
Perennibranchians
Permanently aquatic salamanders with bushy external gills both as larvae and adults.
Anura
Frogs and Toads
Tailless amphibians usually with large hind limbs adapted for jumping and swimming.
Most lay eggs that hatch into tadpoles, which metamorphose into adults.
Lalagobatrachia
Calling Frogs
All frogs other than tailed and New Zealand frogs. They communicate by calling and most have vocal sacs.
Neobatrachia
