Abstract:
Worm lizards (Amphisbaenia) are burrowing squamates that live as subterranean predators. Their underground existence should limit dispersal, yet they are widespread throughout the Americas, Europe and Africa. This pattern was traditionally explained by continental drift, but molecular clocks suggest a Cenozoic diversification, long after the break-up of Pangaea, implying dispersal. Here, we describe primitive amphisbaenians from the North American Palaeocene, including the oldest known amphisbaenian, and provide new and older molecular divergence estimates for the clade, showing that worm liza

Abstract:
We studied the thermal ecology of the amphisbaenian Trogonophis wiegmanni at the Chafarinas Islands (North Africa). We aimed to evaluate the extent of thermoregulation in this fossorial amphisbaenian by analyzing the relationships between environmental available operative (Te) and body (Tb) temperatures of active individuals found under stones. Amphisbaenians are typical thigmotherms that obtain heat through contact with soil and, thus, Tb was closely correlated to Te under stones. However, the comparison of Tb with Tes available in the study area indicated that Tb deviated less from the set-p

Morphological adaptations for burrowing, such as an elongated body, and a small head may constrain feeding behaviour in fossorial reptiles. We experimentally examined the effect of prey type on prey capture and handling behaviour of the amphisbaenian Blanus cinereus. This amphisbaenian showed four different handling modes according to the characteristics of each prey type. When prey diameter was narrower than gape-size, prey were consumed without prey processing; when prey diameter was wider than gape-size, B. cinereus shifted handling mode to prey processing.

SUMMARYBlood parasites such as haemogregarines and haemosporidians have been identified in almost all groups of vertebrates. However, very little is known about biodiversity of these parasites and their effects on some major groups of reptiles such as amphisbaenians, a distinctive group with many morphological and ecological adaptations to fossorial life. Conditions of the fossorial environment might also affect host–parasite relationships.

Abstract:
Populations of terrestrial or freshwater taxa that are separated by oceans can be explained by either oceanic dispersal or fragmentation of a previously contiguous land mass. Amphisbaenians, the worm lizards (approx. 165 species), are small squamate reptiles that are uniquely adapted to a burrowing lifestyle and inhabit Africa, South America, Caribbean Islands, North America, Europe and the Middle East. All but a few species are limbless and they rarely leave their subterranean burrows. Given their peculiar habits, the distribution of amphisbaenians has been assumed to be primarily the result

The White-necked Hawk (Amadonastur lacernulatus) is an Atlantic Forest endemic bird of prey with a poorly known diet. Here, we describe three different predatory interactions between White-necked Hawks and worm lizards (Amphisbaenidae) from Ubatuba, São Paulo, Brazil. During these events, hawks were recorded grasping, killing and consuming amphisbaenids. Due to their fossorial life, worm lizards are uncommon prey items for most birds of prey and such predator-prey interaction can be related to flooded amphisbaenians galleries after heavy rain episodes.

Morphological adaptations of amphisbaenians to fossorial life might affect their antipredator-behavior decisions. Amphisbaenians exposed on the soil surface by a predator can escape by burrowing immediately or by using alternative defensive behaviors on the soil surface, and should decide where to burrow in order to return to their home range. We simulated in the laboratory predatory attacks toward individual amphisbaenians (Blanus cinereus), and examined whether their antipredator and burrowing responses were affected by site familiarity (familiar versus unfamiliar substrate) and their intern
