This appears to echo the greater need for REM sleep among newborns than among adults in most mammal species. Many mammals sleep for a large proportion of each 24-hour period when they are very young. [66] The giraffe only sleeps 2 hours a day in about 5–15 minute sessions. Koalas are the longest sleeping-mammals, about 20–22 hours a day.
They are most active in cold temperatures, specifically between 9.1 and 20.2 degrees Celsius. [16] [17] During the day, N. maculosus seeks refuge under rocks or logs and plant debris. [15] They forage during the night and eat a variety of prey, but have preference for crayfish. [4] During the winter and spring, N. maculosus will also eat fish. [5]
The eggs are not pigmented and are about 5–6 mm (0.20–0.24 in) mm in diameter. The female stays with her eggs during the incubation period (around 40 days). Hatchlings are about 2.5 cm (0.98 in) long and grow to 3.6 cm (1.4 in) before the yolk is completely consumed. [7]
Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.
During the day, amphiumas hide in vegetation, and at night they become active hunters. Their prey includes frogs , snakes , fish , crustaceans , insects and even other amphiumas. Hunting and eating habits have been observed to be very similar to that of the axolotl , including the sucking in of food by their stomachs with vacuum force.

The glass frogs belong to the amphibian family Centrolenidae (order Anura), native to the Central American Rainforests.The general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent, giving the glass frog its common name.
The list below largely follows Darrel Frost's Amphibian Species of the World (ASW), Version 5.5 (31 January 2011). Another classification, which largely follows Frost, but deviates from it in part is the one of AmphibiaWeb , which is run by the California Academy of Sciences and several of universities.
