Who Is Likely to Cheat? Linking Personality to Worthless Gift Production in a Spider
Ethology, Volume 131, Issue 12, Page 313-320, December 2025.Male spiders of Pisaura mirabilis use two strategies to court females: offering either nutritious gifts or worthless ones. Our study shows that aggressive and larger males are more likely to use worthless items, highlighting how individual differences in behaviour and body size influence these tactics. These findings reveal how personality and physical

Marine Biodiversity Records, 2011 Here we report on intraspecific cleaning behaviour between two adult bluestreak cleaner wrasse Labroides dimidiatus of similar size on coral reefs surrounding Lizard Island, Great Barrier Reef, Australia. During a SCUBA dive, we observed these individuals posing and the resulting cleaning interactions. While aggression in this species is common between

The influence of sleep disruption on learning and memory in fish
Journal of Sleep Research, Volume 34, Issue 6, December 2025.Summary Sleep is a ubiquitous process that has been conserved in animals. Yet, our understanding of the functions of sleep largely derives from a few species. Sleep is considered to play an important role in mental processes, including learning and memory consolidation, but how widespread this relationship is across taxa remains unclear.

The role of serotonin in the modulation of cooperative behavior [PDF]
, 2017 We examined the modulatory role of serotonin in cooperation between unrelated individuals. The identification of the neurohormonal candidates that may modulate levels of cooperation in marine cleaning mutualisms has been a major aim in recent years.

The Role of Live and Dead Corals in Shaping Fish Assemblages Across Life Stages
Ecology and Evolution, Volume 15, Issue 11, November 2025.We assessed the effects of experimental patches of live and dead corals on reef fish assemblages in different live stages. While dead and live corals provided equal shelter for mobile recruits, only live corals supported higher post‐recruit abundance, species richness, and functional diversity.

Journal of Zoology, Volume 327, Issue 1, Page 19-27, September 2025.The false cleanerfish (at the front), Aspidontus taeniatus (Blenniidae), mimics the bluestreak cleaner wrasse (Labroides dimidiatus, Labridae), a well‐known cleaner fish on coral reefs. What makes A. taeniatus mimic so precisely and perfectly? In this study, to explore the advantages of such mimicry, we used three‐dimensional (3D) recordings to examine

Beyond the Binary: Controlling Natural Sex‐Change in Hermaphroditic Fishes
Reviews in Aquaculture, Volume 17, Issue 4, September 2025.ABSTRACT Sex‐change in hermaphroditic fishes is a complex but natural biological phenomenon that has significant implications for aquaculture fingerling production, selective breeding, and grow‐out. Understanding the physiological, endocrinological, and molecular pathways underlying hermaphroditism in fishes offers unique opportunities to manipulate ...

Female-female Spawning and Sex Change in a Haremic Coral-reef Fish, Labroides dimidiatus [PDF]
Zoological Science, 2000 Abstract In the polygynous coral-reef fish, Labroides dimidiatus, the largest female may complete sex change within a few weeks if the male disappears. We conducted male removal experiments just prior to spawning time. The largest female possessing ovulated eggs spawned in the male role with smaller females, 1–2 hr after the male removal, suggesting ...

Cleaning in pairs enhances honesty in male cleaning gobies [PDF]
, 2017 A recent game theoretic model akin to an iterated prisoner's dilemma explored situations in which 2 individuals (the service providers) interact simultaneously with the same service recipient (the client). If providing a dishonest service pays, then each
