“…Parents that are infected with parasites may cannibalise offspring at different rates than uninfected parents. In damselfish, Stegastes planifrons , male parents infected with monogenean parasites exhibit increased partial brood cannibalism, potentially to offset the energetic costs of their infection (Sasal, 2006). Stott & Pulin (1996) also tested for a relationship between parental parasite load and cannibalistic behaviour in male upland bullies, Gobiomorphus breviceps , but failed to find a correlation.…”

Parents that kill and consume their offspring often appear to be acting against their own reproductive interests. Yet parentoffspring cannibalism is common and taxonomically widespread across the animal kingdom. In this review, I provide an overview of our current understanding of parent-offspring cannibalism, which has seen a proliferation in adaptive hypotheses over the past 20 years for why parents consume their own young. I review over four decades of research into this perplexing behaviour, drawing from work conducted on fishes, reptiles, insects, birds, and mammals among other taxa. Many factors have been hypothesised to explain parent-offspring cannibalism in nature, including poor parental energy reserves, small or large brood sizes, low or uncertain parentage, and high brood densities, and additional factors are still being uncovered. Parent-offspring cannibalism does not appear to have a single predominant explanation; rather, the factor, or set of factors, that govern its expression is largely taxon specific. Parents may either consume all offspring under their care (fullbrood cannibalism) or consume a fraction of their offspring (partial brood cannibalism). These forms of cannibalism are thought to provide adaptive benefits to cannibals under a range of circumstances, primarily by allowing parents to allocate parental efforts more optimallyenergy from eating (some of) one's current offspring can be redirected to other offspring, or to parental growth, survival, and ultimately to other future reproductive endeavours. Thus, parent-offspring cannibalism is a phenotypically plastic trait that responds to changing environmental, social, and physiological conditions. The expression of parent-offspring cannibalism in any given system is intimately linked to the reproductive value of current young relative to parents' expectations for future reproduction, and also to whether parental care is predominantly depreciable or non-depreciable. Furthermore, parent-offspring cannibalism has the potential to generate conflict between the sexes, and I briefly discuss some consequences of this conflict on patterns of mate choice. Finally, there still remain many aspects of this behaviour where our understanding is poor, and I highlight these topics to help guide future research.

“…Their territorial behavior is conspicuous and promotes the location and collection of embryos (Gumm, van Breukelen, Draud, & Itzkowitz, ; Haley & Muller, ; Saunders, Harvey, & Kendrick, ). Many species will readily deposit eggs in artificial structures that can promote sampling from the wild (Knapp, ; Petersen, ; Sasal, ). Damselfishes from the genera Amphiprion and Premnas (i.e., the Anemonefishes or Clownfishes; Subfamily Pomacentrinae, Tribe Amphiprionini; Cooper & Santini, ) will also readily breed in aquaria (Allen, ; Anil, Santhosh, Prasad, & George, ; Arbuatti, Amendola, Pantaleo, De Angelis, & Robbe, ; Dhaneesh, Kumar, Swagat, & Balasubramanian, ; Madhu, Madhu, Mathew, & Retheesh, ).…”

Functional morphogenesis from embryos to adults: Late development shapes trophic niche in coral reef damselfishes

The damselfishes are one of the dominant coral reef fish lineages. Their ecological diversification has involved repeated transitions between pelagic feeding using fast bites and benthic feeding using forceful bites. A highly‐integrative approach that combined gene expression assays, shape analyses, and high‐speed video analyses was used to examine the development of trophic morphology in embryonic, larval, juvenile, and adult damselfishes. The anatomical characters that distinguish pelagic‐feeding and benthic‐feeding species do not appear until after larval development. Neither patterns of embryonic jaw morphogenesis, larval skull shapes nor larval bite mechanics significantly distinguished damselfishes from different adult trophic guilds. Analyses of skull shape and feeding performance identified two important transitions in the trophic development of a single species (the orange clownfish; Amphiprion percula): (a) a pronounced transformation in feeding mechanics during metamorphosis; and (b) more protracted cranial remodeling over the course of juvenile development. The results of this study indicate that changes in postlarval morphogenesis have played an important role in damselfish evolution. This is likely to be true for other fish lineages, particularly if they consist of marine species, the majority of which have planktonic larvae with different functional requirements for feeding in comparison to their adult forms.
