Lateralization of eye use in cuttlefish: opposite direction for anti-predatory and predatory behaviors. [PDF]
Frontiers in Physiology, 2016 Vertebrates with laterally placed eyes typically exhibit preferential eye use for ecological activities such as scanning for predators or prey. Processing visual information predominately through the left or right visual field has been associated with ...

Physical evidence of predatory behavior in Tyrannosaurus rex. [PDF]
Proc Natl Acad Sci U S A, 2013 Feeding strategies of the large theropod, Tyrannosaurus rex , either as a predator or a scavenger, have been a topic of debate previously compromised by lack of definitive physical evidence. Tooth drag and bone puncture marks have been documented on suggested prey items, but are often difficult to attribute to a ...

Predatory behavior of the land flatworm Notogynaphallia abundans (Platyhelminthes: Tricladida) [PDF]
Zoologia (Curitiba), 2009 Land flatworms are carnivorous, mainly predators. However, knowledge on their predatory behavior and prey preference is very scarce. This paucity of data is a limiting factor in the study of their biology and organismal ecology, resulting in a very ...

Serotonin Drives Predatory Feeding Behavior via Synchronous Feeding Rhythms in the Nematode Pristionchus pacificus [PDF]
G3: Genes, Genomes, Genetics, 2017 Feeding behaviors in a wide range of animals are regulated by the neurotransmitter serotonin, although the exact neural circuits and associated mechanism are often unknown.

Predatory Behavior of the Basilica Spider, Mecynogea Lemniscata (Araneae, Araneidae) [PDF]
Psyche: A Journal of Entomology, 1992 Females of Mecynogea lemniscata (Walckenaer) are generalist predators. Sixteen behavioral acts were described for M. lemniscata preying on house flies, carpenter ants, and Asiatic oak weevils in the field and laboratory.

Predatory Luring Behavior of Odonates [PDF]
Journal of Insect Science, 2014 Organisms in the order Odonata are highly predatory insects that have a wide distribution globally. To date, there has been zero evidence that odonates employ luring as a means of prey acquisition. However, in this study, we show that Aeshna palmata larvae use abdominal movements to lure larval Argia vivida, subsequently consuming the lured organism ...

The predatory behavior of Pheidole megacephala
Comptes Rendus. Biologies, 2007 We studied the foraging and predatory behaviors of the invasive African myrmicine ant, Pheidole megacephala (F.) in its native range. Workers can singly capture a wide range of insects, including relatively large prey items.

Frontiers in Physiology, 2020 Cuttlefish are highly efficient predators, which strongly rely on their anterior binocular visual field for hunting and prey capture. Their complex eyes possess adaptations for low light conditions.

Acta Biológica Colombiana, 2021 The Channel-billed Toucan (Ramphastos vitellinus ariel) is an omnivorous bird that eventually is nest-robbers. Several birdsongs display anti-predatory strategies such as attacks and mobbing calls to face this kind of predators.
