Eusocial insects can express surprisingly complex cooperative defence of the colony. Brood and reproductive castes typically remain in the nest and are protected by workers' various antipredator tactics against intruders. In Madagascar, a myrmicine ant, Aphaenogaster swammerdami , occurs sympatrically with a large blindsnake, Madatyphlops decorsei . As blindsnakes generally specialize on feeding on termites and ants brood by intruding into the nest, these snakes are presumably a serious predator on the ant. Conversely, a lamprophiid snake, Madagascarophis colubrinus , is considered to occur often in active A . swammerdami nests without being attacked. By presenting M . colubrinus , M . decorsei and a control snake, Thamnosophis lateralis , at the entrance of the nest, we observed two highly specialized interactions between ants and snakes: the acceptance of M . colubrinus into the nest and the cooperative evacuation of the brood from the nest for protection against the ant-eating M . decorsei . Given that M . colubrinus is one of the few known predators of blindsnakes in this area, A . swammerdami may protect their colonies against this blindsnake by two antipredator tactics, symbiosis with M . colubrinus and evacuation in response to intrusion by blindsnakes. These findings demonstrate that specialized predators can drive evolution of complex cooperative defence in eusocial species.

Worm-like snakes (scolecophidians) are small, burrowing species with reduced vision. Although largely neglected in vertebrate research, knowledge of their biogeographical history is crucial for evaluating hypotheses of snake origins. We constructed a molecular dataset for scolecophidians with detailed sampling within the largest family, Typhlopidae (blindsnakes). Our results demonstrate that scolecophidians have had a long Gondwanan history, and that their initial diversification followed a vicariant event: the separation of East and West Gondwana approximately 150 Ma. We find that the earliest blindsnake lineages, representing two new families described here, were distributed on the palaeolandmass of India+Madagascar named here as Indigascar. Their later evolution out of Indigascar involved vicariance and several oceanic dispersal events, including a westward transatlantic one, unexpected for burrowing animals. The exceptional diversification of scolecophidians in the Cenozoic was probably linked to a parallel radiation of prey (ants and termites) as well as increased isolation of populations facilitated by their fossorial habits.

We report the second known museum specimen of Typhlops tycherus, a blindsnake endemic to Honduras. This new specimen is from a locality about 240 km from the species’ type locality, thus documenting that T. tycherus has a broader geographical distribution than previously thought.

In this study we report on two new records of the blindsnake Typhlops brongersmianus for the municipality of Bauru, midwestern region of the state of São Paulo, Brazil. These records expand the geographic distribution currently known for this species in the state and contribute to the knowledge of snakes in southeastern Brazil.

Blindsnakes (Typhlopidae) represent one of the least known elements of the Australian herpetofauna. Mitochondrial DNA sequence data and morphology are used here to show that a widespread species of Australian blindsnake, Ramphotyphlops australis, comprises two distinct species. Ramphotyphlops bicolor (new combination) is resurrected from synonymy with R. australis and redescriptions are provided for both species. Mitochondrial DNA sequence variation within R. australis indicates that the central and south-coast populations are more closely related to each other than either is to the morphologically distinctive populations at the northern edge of the species' range. Observed levels of differentiation suggest historical isolation of populations from the Kalbarri/Shark Bay region of the western Australian coastline. However, lack of concordance between mitochondrial haplotype phylogeny and morphology for several individuals might reflect limited gene flow between the northern and south–central populations. We note that many taxa show restricted distributions or range disjunctions along the central Western Australian coastal margin, and we discuss possible models to explain population fragmentation in this region. Pliocene–Pleistocene sea-level fluctuations along the western Australian coast could have isolated sand plain communities in the Kalbarri/Shark Bay region from similar communities further south near Geraldton, possibly underlying the phylogeographic pattern in R. australis. Data from additional taxa will be needed to fully evaluate this hypothesis.

Most recent phylogenetic analyses of snakes have recognized two major clades within Serpentes: Alethinophidia and Scolecophidia. Alethinophidians feed predominantly on relatively large vertebrate prey, which they transport into and through the mouth via reciprocating ratcheting movements of the toothed palatopterygoid jaw arches. In contrast, scolecophidians are small-prey specialists, feeding almost exclusively on small arthropods. In addition, these diminutive, fossorial snakes lack many of the key morphological features which underlie the feeding mechanisms of alethinophidians, such as toothed palatopterygoid jaw arches and a distensible lower jaw. However, the functional significance of these morphological differences has remained poorly understood because there have been no detailed descriptions of feeding behavior in Scolecophidia. I used magnified high-speed videography, videofluoroscopy, and standard histological and gross morphological preparations to study the functional morphology of the feeding apparatus in representatives of two families of Scolecophidia, Leptotyphlopidae and Typhlopidae. In Leptotyphlops (Leptotyphlopidae), a mandibular raking mechanism is used to capture, ingest and transport prey. In this mechanism, the toothed anterior portions of the mandibular rami are rotated medially about the intramandibular joints in a bilaterally synchronous fashion. In contrast, Typhlops and Rhinotyphlops (Typhlopidae) feed via a maxillary raking mechanism, in which asynchronous rotations of the toothed maxillae are used to drag prey into and through the mouth. Both mandibular raking and maxillary raking involve exceptionally rapid (3–5 Hz) movements of the tooth-bearing elements of the jaws, thereby facilitating the ingestion of large numbers of small prey within relatively brief periods of time.

This chapter examines snakes, starting with the Boa Constrictor. The arrival of the Boa Constrictor to the United States was associated with the pet trade, where it was first reported from Miami, Miami-Dade County, Florida, in 1994 and thought to have been established. In light of its broad diet and potentially large body size, the Boa Constrictor places a wide range of vertebrates at risk through its depredations. Interestingly enough, however, unlike the Burmese python, the Boa Constrictor has remained confined to a small, if thriving, colony. The chapter then looks at harmless live-bearing snakes, including the Southern Watersnake, the Common Watersnake, and the Short-headed Gartersnake. It also considers pythons and blindsnakes.
