Arachnids that feed on vertebrate carrion: necrophagy by the whip spider Paraphrynus raptator (Amblypygi: Phrynidae) and its relation to the feeding behavior of the woolly false vampire bat Chrotopterus auritus (Chiroptera: Phyllostomidae)

Resumen:
Necrophagy is a feeding strategy in which animals feed on carrion; most
scavengers are facultative and can also be predators or consumers. For
amblypygids, necrophagy is a poorly documented phenomenon and there are
literature records of individuals of three different species feeding on
dead bats inside caves. In the present note, we document for the first
time a necrophagic behavior in the whip spider Paraphrynus raptator
(Pocock, 1902) which was observed feeding on Otonyctomys hatti Anthony,
1932 (Rodentia: Cricetidae) and a yucatan poorwill, Nyctiphrynus
yucatanicus Hartert, 1892 (Caprimulgiformes: Caprimulgidae) carrion. We
made the observations inside a small chamber in an ancient Mayan temple
inhabited by a group of woolly false vampire bats (Chrotopterus auritus
Peters, 1856) in southeastern Mexico. Carrion consumption in P. raptator
is directly related with the carnivorous feeding behavior of the C.
auritus group with which they coexist.
