Summary Previously, giant water bugs (BeloslOma sp. , Belostomatidae) were thought to be the only predators of the cavedwelling fish Poecilia mexicana (Poeciliidae) in a southern Mexican sulphur ca ve (Cueva del Azufre). Here, we report on th ree species of Araneae [Ctenidae ge n. sp. , Tinus sp. (Pisauridae), and Hemirrhagus pernix (Theraphosidae)] from that cave, which also prey on P. mexicana. To our knowledge, this is the first report of spider predation on a cave fish. 
Giant water bug (Belostoma sp.) predation on a cave fish (Poecilia mexicana): effects of female body size and gestational state
TLDR
Pregnant females and pregnant females are targeted by giant water bugs in a sulphidic cave in Tabasco, Mexico, and water bugs clearly preferred pregnant over non-pregnant prey.
Population Structure, Habitat Use, and Diet of Giant Waterbugs in a Sulfidic Cave
TLDR
It is inferred that waterbugs reproduce inside the cave despite the toxic properties of the water, as evidenced by the presence of nymphs of all sizes and males carrying developing zygotes, and stable-isotope-analysis indicated that waterbug likely derive their carbon from a combination of fish, dipteran larvae, and chemoautotropic bacteria.

TLDR
This work provides a general overview of the spider families recorded in hypogean habitats worldwide, a review of the different adaptations of hypOgean spiders to subterranean life, and summary of the information gathered so far about their origin, population structure, ecology and conservation status.
Fish Predation by Semi-Aquatic Spiders: A Global Pattern
TLDR
It is provided that fish predation by semi-aquatic spiders is geographically widespread, occurring on all continents except Antarctica, and that fish prey might be an occasional prey item of substantial nutritional importance.
Extreme habitats are not refuges: poeciliids suffer from increased aerial predation risk in sulphidic southern Mexican habitats
TLDR
It is demonstrated that extreme environments do not necessarily represent a refuge from predation, and it is hypothesized that natural selection via avian predation may play an important role in maintaining reproductive isolation between divergent poeciliid populations.
Predator Avoidance in Extremophile Fish
TLDR
The results indicate that predator avoidance is still functional in extremophile Poecilia spp.
Behaviour, feeding habits and ecology of the blind catfish Phreatobius sanguijuela (Ostariophysi: Siluriformes).
TLDR
The subterranean fish Phreatobius sanguijuela, originally described from Bolivia, was captured in different wells near São Francisco do Guaporé, Rondônia State, Brazil and exhibited cryptobiotic habits and two behaviours under stressful conditions.
Toxic hydrogen sulphide and dark caves: pronounced male life‐history divergence among locally adapted Poecilia mexicana (Poeciliidae)
TLDR
Strong evidence for local adaptation as a result of ecologically based divergent selection in the neotropical fish Poecilia mexicana is found and it is proposed that apparent conservatism of male life histories is the result of other (genetically based) changes in physiology and behaviour between populations.
Insights into the Social Behavior of Surface and Cave-Dwelling Fish (Poecilia mexicana) in Light and Darkness through the Use of a Biomimetic Robot
TLDR
This is the first study to use biomimetic robots for the investigation of social behavior in mollies and to compare responses to BRs both in light and darkness.

Predation of a cave fish (Poecilia mexicana, Poeciliidae) by a giant water‐bug (Belostoma, Belostomatidae) in a Mexican sulphur cave
TLDR
The predator–prey interaction of a belostomatid (predator) and a cave fish (prey) occurring in the Cueva del Azufre (Tabasco, Mexico) was investigated with two separate experiments.
Male-biased predation of a cave fish by a giant water bug
TLDR
It is found that males typically exhibit more ASR activity than females, which leads to increased exposure to the sit-and-wait predator that catches fish near the water surface.
FISHING BEHAVIOR IN A GIANT WHIP SPIDER
TLDR
A remarkable foraging strategy adopted by the giant tropical whip spider Heterophrynus cheiracanthus inhabiting rocky outcrops adjacent to mountain streams running through primary tropical rainforest on the Caribbean island of Tobago is reported.
Does a predatory insect contribute to the divergence between cave- and surface-adapted fish populations?
  • M. Tobler
  • Environmental Science, Biology

  • 2009
TLDR
This study investigated whether a predatory aquatic insect selects against migrants between cave and surface populations of a fish (Poecilia mexicana), finding cavefish were more susceptible to attacks in the light, whereas surface fish were more susceptibility in darkness.
A ‘SWIMMING’ HETEROPODA SPECIES FROM BORNEO (ARANEAE, SPARASSIDAE, HETEROPODINAE)
TLDR
Heteropoda natans new species (Araneae, Sparassidae, Heteropodinae) is described from Borneo and the lectotype of H. hosei is designated.
Life on the edge: hydrogen sulfide and the fish communities of a Mexican cave and surrounding waters
TLDR
The study revealed high concentrations of H2S in the cave and its outflow and discussed that P. mexicana is one of the few extremophile vertebrates, which supports the idea that extreme habitats lead to an impoverished species diversity.
A Cavernicolous Form of the Poeciliid Fish Poecilia sphenops from Tabasco, Mexico
TLDR
The reproductive behaviour of the ten-spined stickleback (Pygosteus pungitius L.) and the cottid fish Oligocottus snyderi Greeley are studied.
The role of sexual harassment in cave and surface dwelling populations of the Atlantic molly, Poecilia mexicana (Poeciliidae, Teleostei)
TLDR
In the cave molly, small males are at a disadvantage in female choice, but predation by an aquatic heteropteran selects against large male body size.
Survival in an extreme habitat: the roles of behaviour and energy limitation
TLDR
It is demonstrated that a behavioural adaptation, aquatic surface respiration (ASR), allows for the survival of P. mexicana in this extreme, sulphidic habitat, while without the possibility to perform ASR, the survival rate was low even at comparatively low H2S concentrations.
The end of regressive evolution: examining and interpreting the evidence from cave fishes.
TLDR
It is argued that evolution of hypogean fauna can be explained by well-known mechanisms within the current context of evolutionary biology.
