Animal defenses are often studied as a coherent and functional group of mechanisms that work against multiple predators, but that is usually not the case. Not much is known on the possibility specific defensive mechanisms are used against specific predators and that distinct defensive mechanisms have distinct efficiencies against different predators. Another unexplored aspect is the impor…
Chemoreception is a sensory modality used by many species of vertebrates and invertebrates, but not well understood in several groups such as harvestmen (Opiliones, Arachnida). Recent studies have shown that not only contact chemoreception but also olfaction is important, but there are no olfactory receptors described, no extensive behavioral study on olfaction, and no studies on the evol…

Scorpion envenomation represents a serious concern for public health worldwide, causing thousands of deaths yearly, in special in tropical and subtropical countries. In Brazil, these animals are the second leading cause of human poisoning, with the northeastern region being the most affected. These accidents are mainly associated with the scorpion Tityus serrulatus, whose population growt…
Present on practically all continents, with the exception of Greenland, scorpions represent a timeless problem that affects a large portion of humanity. Thousands of children die every year from scorpion accidents. Physical control, with the active collection and removal of these animals from large urban centers, has not reduced the number of accidents and chemical control is still ineffi…
Almost all harvestmen (Arachnida, Opiliones) species produce chemical secretions that vary in nature and some harvestmen species have conspicuous coloration, the latter being putative signals. However, up to now, the effectiveness of those different compounds has not been compared in the light of a wide range of selective pressures predators might exert. And even though bright colors have…
Behavioral syndromes are correlations between the behavior of the individuals in different contexts or different times of their life. The behavioral syndromes have been shown in vertebrates and invertebrates. The goal of this study is to investigate the presence of behavioral syndromes in Charinus asturius (Amblypygi), a group relatively poorly studied in respect to its general aspects an…

When compared with other arachnids, the sensilla' fine morphology of the four suborders of Opiliones is poorly know. Specially in Laniatores, the largest suborder, no olfactory receptor has been identified, and only one study, in the suborder Eupnoi, has provided detailed information on gustatory receptor's internal morphology. This is a considerable gap in sensory biology of Opiliones, c…
Fleeing from predators envolve the detection and decision about when to start fleeing. Two hypotheses that exist in the literature are that (1) prey must flee when the distance of the predator is such that it offers real danger and (2) that the cost of monitoring the predator must also be considered and therefore prey must flee earlier. Therefore, whereas the first predicts fleeing only w…
