In pursuit predation, predators chase fleeing prey. If the prey flees in a straight line, capture depends only on the predator's being faster than the prey. [40] If the prey manoeuvres by turning as it flees, the predator must react in real time to calculate and follow a new intercept path, such as by parallel navigation, as it closes on the ...
Prithee and pray you often coincide in Early Modern English texts, and the difference between the two terms has been debated by scholars. Scholars such as Roger Brown and Albert Gilman have suggested that prithee was an ingroup indicator.
Experiments on blue jays suggest they form a search image for certain prey.. Visual predators may form what is termed a search image of certain prey.. Predators need not locate their host directly: Kestrels, for instance, are able to detect the faeces and urine of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example.
The filament can move in all directions and the esca can be wiggled so as to resemble a prey animal, thus acting as bait to lure other predators close enough for the anglerfish to devour them. [8] Some deep-sea anglerfishes of the bathypelagic zone emit light from their escas to attract prey.
Fishers are generalist predators. Although their primary prey is snowshoe hares and porcupines, they are also known to supplement their diet with insects, nuts, berries, and mushrooms. They have been observed eating small apples during winter. Since they are solitary hunters, their choice of prey is limited by their size.
Durophagy requires special adaptions, such as blunt, strong teeth and a heavy jaw. [5] Bite force is necessary to overcome the physical constraints of consuming more durable prey and gain a competitive advantage over other organisms by gaining access to more diverse or exclusive food resources earlier in life. [6]
The skin is semi-permeable, making them susceptible to dehydration, so they either live in moist places or have special adaptations to deal with dry habitats. Frogs produce a wide range of vocalisations , particularly in their breeding season , and exhibit many different kinds of complex behaviors to attract mates, to fend off predators and to ...
Sharks and the orca basically eat their prey alive; but in sections for the larger prey, notably seals. Pearce argues, through analogy, how the idea of intelligent aliens creating stylised portrayals of human deaths for popular entertainment would be considered abhorrent; he asserts that, in reality, this is the role that humans play when ...
