..a small species of microhylid frog that its native to Papua New Guinea. P. amauensis was discovered recently (2009) and was described in 2012. Paedophryne amaeuensis is largely considered to one of the smallest known vertebrates with adults only growing to 7.7 mm in length. Interestingly P. amauensis lives its entire live on land and goes not have a tadpole stage, instead they hatch as miniature adults. Due to their small size their skeleton is reduced and only seven presacral vertebrae are present. Like other members of Paedophryne, P. amauensis is crepuscular and lives in leaf litter and likely feeds on small insects and springtails.
Scaphiophryne spinosa is a species of frog in the Microhylidae family. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, subtropical or tropical moist montane forests, intermittent freshwater marshes, and heavily degraded former forest. It is threatened by habitat loss.

It’s also known as Black-spotted narrow-mouthed frog, or Rufous-sided sticky frog. The Black-spotted sticky frog is found in South Asia from southern China, Burma and Thailand through peninsular Malaysia to Sumatra, Java, Borneo and parts of the Philippines.
This species is only known from the forests of Betampona Reserve, in eastern Madagascar. Within the protected area it is known from six sites.
Morphology & Colouration:
Platypelis karenae belongs to a group of particularly small Platypelis species, and reaches a maximum length of around 18 mm. It possesses round, expanded toe pads, unwebbed fingers and toes, and smooth dorsal skin. Its hindlimbs are fairly short, and tibiotarsal articulation reaches only the tympanum.
Adults are yellowish to greenish, with a dark dorsolateral stripe extending from the eye beyond the forearm. Juveniles have a red snout and iris, and possess lighter spots on the dorsum. The venter is whitish.
This species inhabits phytotelms within Pandanus and Crinum plants (related species are only known from Pandanus), not more than ten metres from streams. Females lay small clutches of around 2-3 eggs, and guard them. The call of the male consists of repeated melodious notes over many minutes. Peak calling activity is during rainfall. Males ascend to the outer parts of their plants to call.
Platypelis karenae was proposed to be Near Threatened on the IUCN Red List, but is such a new species that it has not yet been listed. This status was proposed because it is at risk of becoming vulnerable to extinction by invasive guava plants that threaten to displace the phytotelmic plants it inhabits, as well as typical threats such as deforestation and decline in habitat quality. It remains relatively well protected within Betampona, but has probably been lost from most of its range because the lowland forests of Madagascar have been so drastically deforested.
Taxonomy & Systematics:
Platypelis karenae is genetically most closely related to P. tuberifera, but differs strongly from that species in its call (much slower than the three calls per second of P. tuberifera) and appearance (it is much smaller and has a different pattern). In appearance it most resembles P. tetra, but is lighter in colour, lacks speckling in the adults, has different relative toe lengths, and lacks dorsal tubercles.
