“…Predation is achieved with a pair of modified legs (forcipules) located ventrally and preceding the head and mouth. Venom from a gland at the forcipule base kills prey via injection (Malta et al 2008;Dugon and Arthur 2012a,b). Centipedes are thought to feed predominantly on prey alive (Voigtländer 2011), which are generally seized with the anterior legs then envenimated via a stabbing motion of the forcipules (Dugon and Arthur 2012b).…”

Centipedes are opportunistic carnivore predators, and large species can feed on a wide variety of vertebrates, including bats. The aim of this study was to report the third record of bat predation by centipedes worldwide, the first record in the Amazon region, while covering aspects of foraging, capture and handling of prey. We observed the occurence in a fortuitous encounter at Cristalino State Park, located in the Amazon region of the state of Mato Grosso, Brazil. The attack took place in a small wooden structure, at about three meters from the floor, and was observed for 20 minutes. During the observation, the centipede stung the neck and abdominal region of the bat several times, grabbing the prey with its 15 pairs of front legs while hanging from the ceiling with its hind legs. This type of observation suggests that vertebrates can be important preys for invertebrates such as giant centipedes, both for its nutritional composition and for the amount of energy available in a single prey.

Predação de morcego (Molossus molossus: Molossidae) pela centopeia Scolopendra viridicornis (Scolopendridae) no sul da Amazônia RESUMOCentopeias são predadores carnívoros oportunistas e grandes espécies podem se alimentar de uma grande variedade de vertebrados, inclusive de morcegos. O objetivo desse trabalho é reportar o terceiro registro de predação de morcego por centopeia, e o primeiro para a região Amazônica, abrangendo aspectos do forrageamento, captura e manipulação da presa. O registro foi realizado de forma fortuita, no Parque Estadual do Cristalino, região de Floresta Amazônica, no estado de Mato Grosso, Brasil. O ataque ocorreu em uma estrutura de madeira a cerca de três metros de altura e foi observado por 20 minutos. Durante a observação, a centopeia picou várias vezes o pescoço e região abdominal do morcego, agarrando a presa com seus 15 pares de pernas anteriores e se pendurando ao teto com as pernas posteriores. Esse tipo de observação sugere que vertebrados podem ser importantes presas para invertebrados, como centopeias gigantes, tanto por sua composição nutricional quanto pela quantidade de energia disponível em uma única presa.

“…The variety of active proteins contained in the venom of S. viridicornis (MaLta et al 2008), as well as its size and most offensive behavior, favor a wider alimentary variety, including the intake of sizeable prey items. The biochemical properties of the venom of O. tibialis and C. iheringi, along with smaller body size, seem to be limiting factors to food diversity, but may indicate more specificity in their venom.…”

“…Protein samples dissolved in SDS-probe buffer without heating were loaded on 10% SDS-polyacrylamide gels (10% 13 cm Â 10 cm Â 0.1 cm) containing 0.04% gelatin or 0.2% casein (Laemmli, 1970;Malta et al, 2008;Já mbrik et al, 2010). The gels were run at 4 8C in dark (Schlereth et al, 2000).…”

“…It is well known, that venoms of snakes and centipede with haemorrhagic and haemolytic activities contain proteases (97-15 kDa and 121, 44-15 kDa, respectively) with gelatinolytic and weak caseinolytic activities (Hasson et al, 2004;Malta et al, 2008). Gelatin zymography (SDS-PAGE incorporating gelatin, that is denatured collagen) was demonstrated as an efficient and reasonable method for identifying proteolytic enzymes and measuring gelatinolytic activity as infallible measure of venom haemorrhagic activity (Bee et al, 2001;Hasson et al, 2004).…”
