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)
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 ...

bioRxiv, 2021 The diet of an individual is a result of the availability of dietary items and the individual’s foraging skills and preferences. Behavioral differences may thus influence diet variation, but the evolvability of diet choice through behavioral evolution ...

Emotions and Dog Bites: Could Predatory Attacks Be Triggered by Emotional States?
Animals, 2021 Dog biting events pose severe public health and animal welfare concerns. They result in several consequences for both humans (including physical and psychological trauma) and the dog involved in the biting episode (abandonment, relocation to shelter and ...

Interaction between spiders and ticks-ancient arthropod predatory behavior? [PDF]
Parasitol ResAbstractTicks are ectoparasite vectors of pathogens affecting human and animal health worldwide. Rational integration of different control interventions including plant-derived repellents and acaricides, management of natural predators, and vaccines is required for innovative approaches to reduce the risks associated with ticks and tick-borne diseases.

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 ...
