To be or not to be . . . a flower? A test of possible cues influencing hunting site selection in subadult females of the crab spider Epicadus heterogaster (Guerin 1812) (Araneae: Thomisidae)
(Taylor & Francis Ltd, 2012-01-01)
Females of some Thomisidae species are known to use visual and olfactory stimuli to select high quality hunting sites. However, because studies about foraging behavior in this family are concentrated on a few species, the ...
Unidirectional Optomotor Responses and Eye Dominance in Two Species of Crabs
(Frontiers Media S.A., 2019-05)
Animals, from invertebrates to humans, stabilize the panoramic optic flow through compensatory movements of the eyes, the head or the whole body, a behavior known as optomotor response (OR). The same optic flow moved ...
The crab Neohelice (=Chasmagnathus) granulata: An emergent animal model from emergent countries
(Springer, 2010-05)
Neohelice granulata (previously known as Chasmagnathus granulata and C. granulatus) is a burrowing semiterrestrial crab found in the intertidal zone of estuaries, salt marshes and mangroves of the South-western Atlantic ...
Visuo-motor transformations involved in the escape response to looming stimuli in the crab Neohelice (=Chasmagnathus) granulata
(Company of Biologists, 2012)
Escape responses to directly approaching predators represent one instance of an animal s ability to avoid collision. Usually, such responses can be easily evoked in the laboratory using two-dimensional computer simulations ...
Feeding behavior of a crab according to cheliped number
(2015-12-01)
Cheliped loss through autotomy is a common reflexive response in decapod crustaceans. Cheliped loss has direct and indirect effects on feeding behavior which can affect population dynamics and the role of species in the ...
Organic matter affects fiddler crab distribution? Results from field and laboratorial trials
(2018-11-15)
Fiddler crabs are a key benthic macrofauna group in estuarine environments. Species distribution is determined by relatively distinct zones, based on biotic and abiotic factors. As sediment organic matter is thought to be ...
Differences in the escape response of a grapsid crab in the field and in the laboratory
(Company of Biologists, 2015-09)
Escape behaviours of prey animals are frequently used to study the neural control of behaviour. Escape responses are robust, fast, and can be reliably evoked under both field and laboratory conditions. Many escape responses ...
