“…In contrast to Neff's () results on L . macrochirus , the energy replenishing hypothesis was not supported in this study as no significant relationship between body condition and the number of embryos cannibalized for guarder males was observed (Rohwer, ; Sargent, ; Sargent et al ., ; Bose et al ., ). Conversely, other studies have instead found a positive relationship between condition and number of cannibalized offspring in other species including the long‐snout clingfish Diademichthys lineatus (Sauvage 1883; Gomagano & Kohda, ) and three‐spined sticklebacks Gasterosteus aculeatus L. 1758 (Mehlis et al ., ).…”

The macroscopic and microscopic diversity of potential food items available in the nests of plainfin midshipman Porichthys notatus were quantified and compared with items that were found in the stomach and intestine (digestive tract) of the guarding males. In this species, males occur as one of two possible reproductive morphs: guarder males that care for young and sneaker males that parasitize the courtship and care of guarder males. Although it was predicted that guarder males would have fewer feeding opportunities due to their confinement to the nest, they in fact had more food items in their digestive tracts than did sneaker males and females. Date in the breeding season (a proxy of care duration) and body condition were not correlated with the amount of food consumed by guarder males. The main type of food consumed was P. notatus embryos; 69% of all guarder males sampled had cannibalized offspring. By comparing the diet of both sexes and tactics, this study sheds light on some of the strategies designed to cope with the costs of providing parental care.

“…Cannibalism is defined as the act or practice of one individual of an animal species consuming all of or part of another individual of the same species, and has been documented in several animal taxa [Fox, 1975;Polis et al, 1984;Elgar and Crespi, 1992;Richardson et al, 2010], e.g., insects [Bayoumy and Michaud, 2015;Lesne et al, 2016; reviewed by Richardson et al, 2010], fishes [Manica, 2002;Bose et al, 2014], birds [Jensen et al, 2006], and mammals [Steyn and Funston, 2006;Dorward, 2014]. Although a relatively rare event in wild non-human primates, cannibalism has been reported in 13 of over 470 species.…”

Placentophagia or the consumption of the afterbirth is reported in many primate species, whereas cannibalism is a relatively rare event. Based on our field observations over the course of 3 years, we present evidence of placentophagia and mother-infant cannibalism in a free-ranging population of the Taihangshan macaque, Macaca mulatta tcheliensis, in the Mt. Taihangshan area, Jiyuan, Henan, China. We documented 1 case in which a mother consumed the afterbirth of her infant. In a second instance, we observed a fresh placenta discarded on the ground by an unknown individual. We also present a description of the first documented instance of mother-infant cannibalism in the same group of free-ranging rhesus macaques.

“…This energy can be invested in the remaining progeny or in future reproduction. This Benergy-based hypothesis^re-ceived considerable attention in the literature (Manica 2002), with studies presenting both support (e.g., Mehlis et al 2009) and contradictory evidence (e.g., Bose et al 2014).…”

“…Thus, recognizing unrelated young already at the egg stage appears to be adaptive. Interestingly, few studies have demonstrated that animals assess their parenthood already at that stage (e.g., Mehlis et al 2010;Bose et al 2014) and evidence for recognition of single eggs is even more scarce (but see Loiselle 1983).…”

“…However, it is best investigated in teleost fishes, thus far, probably because it is especially common in this taxon (Manica 2002). At first, cannibalizing own offspring appears highly detrimental; however, under some conditions, this paradox behavior bears fitness benefits (summarized in Manica 2002; Mehlis et al 2009;Bose et al 2014;Deal and Wong 2016). For example, parents may remove sick or dead embryos from their clutch to reduce the risk of spreading diseases to healthy offspring.…”
