The AmphibiaWeb app provides mobile access to AmphibiaWeb and gives information about all amphibian species (frogs and toads, salamanders and newts, and caecilians), including pictures, sounds, as well as range maps and specimen collection points. The app will find all amphibians around one's current location, or, one can search for amphibians in any location around the world or by name. One can browse through the amphibians by name or image.
This app is based on data from AmphibiaWeb, an online system that provides access to information on amphibian declines, conservation, natural history, and taxonomy.
Range maps displayed derive from the IUCN Global Amphibian Assessment, 2010-2012.
An internet connection (wifi or cellular) is required.
This list may not be complete but is based on published studies.

The name Salientia generally has referred to †Triadobatrachus + Anura (Milner, 1988). Ford and Cannatella (1993) defined it as a stem-based name for amphibians that are more closely related to Anura than to Caudata or Gymnophiona. Synapomorphies that unite all of the currently known taxa in Salientia include 14 presacral vertebrae, elongate and anteriorly directed ilium, presence of a frontoparietal, and a toothless dentary (Milner, 1988). To these, Trueb and Cloutier (1991) added the absence of a lacrimal and unicapitate ribs as other unique synapomorphies, and four other synapomorphies that showed homoplasy among closely related dissorophoid temnospondyls.

NAAMP volunteers contribute their time to help states and USGS to assess frog and toad population trends. Data are collected using a calling survey technique, in which volunteers identify local amphibian species by their unique breeding vocalizations or calls.
Volunteers are needed to document the statewide distribution of Maryland’s amphibians and reptiles. The goal of the MARA project is to document the current distributions of Maryland’s amphibian and reptile species using a systematic and repeatable approach.
Amphibians are vertebrates of the taxonomic class Amphibia including animals such as frogs and toads (order Anura), salamanders (order Caudata), and caecilians (order Gymnophiona). Thought of as cold-blooded, amphibians are ectotherms, meaning they are unable to regulate their own body temperature independently of the temperature of their surroundings. Amphibians are generally small with thin skin permeable to air and water. With few exceptions, amphibians do not actively care for their young. In general, amphibian reproduction strategy consists of egg-laying and external fertilization of a large number of eggs in a moist or fully aquatic environment. Fertilized eggs develop into amphibian larvae that live part of their lives dependent on an aquatic environment requiring gills and specialized feeding habits. Following a pattern of development unique to amphibians, amphibian larvae undergo marked changes and metamorphose into a terrestrial form that lives on land. Typically, this metamorphosis is demonstrated by loss of gills, changes in overall appearance, and changes in diet.Amphibians live in diverse habitats, often in large numbers, and play several important ecological roles. As consumers, amphibians help regulate populations of the organisms they consume, chiefly invertebrates. As prey items, amphibians are consumed by a variety of larger predators such as reptiles, birds, mammals, fish, predatory invertebrates, and other amphibians. When consumed by larger predators, amphibians transfer the energy and nutrients from amphibian prey items such as small invertebrates to larger predators.
