Summary: This study examines the strategy of red lionfish in pursuing faster prey. The behavior of successfully capturing prey is defined as the "persistent-predation strategy", which includes pure pursuit, uninterrupted motion, and high success rate in strike.

Summary: This review analyzes the biology and ecology of lionfish as an invasive species, with a focus on Cuba. It is found that lionfish has successfully established in Cuban waters, with high population density and reproductive capacity. Further studies are needed to assess the impact of lionfish on ecosystems and develop effective control strategies.

Summary: The number of coral reefs is decreasing due to environmental and anthropogenic reasons, with Pterois volitans adding additional stress by decreasing herbivorous fish numbers. Algal overgrowth interferes with coral growth as they grow together on algal turfs. Parrotfish play a crucial role in coral enhancement by grazing, and this study analyzes the dynamics of the system with parrotfish and P. volitans as prey and predator respectively. The impact of prey refuge is considered, and stable coexistence regions for different parameter spaces are formulated and verified through numerical simulations.

Summary: This study assesses the population characteristics and removal efforts of Indo-Pacific lionfish in the Flower Garden Banks National Marine Sanctuary (FGBNMS) in the Gulf of Mexico. The results show that lionfish in FGBNMS have lower densities, slower growth rates, and can reach older ages compared to lionfish in other regions. This suggests that FGBNMS may exhibit natural resilience to the lionfish invasion.

Summary: The quality of coral reef habitats is declining due to heatwaves and other disturbances, resulting in reduced complexity and energy transfer to higher trophic levels. By using a size-based ecosystem model, researchers found that providing refuge for fish between 5 and 10 cm in length can significantly enhance fish biomass and fisheries productivity. The study also identifies refuge profiles that can improve ecosystem service provision by up to sixfold.

Summary: Fear of predators influences foraging behavior of herbivorous fishes over small spatial scales, with larger group sizes further from predators. These fear effects interact with herbivore group size to shape the distribution and intensity of herbivory, impacting macroalgal removal on coral reefs.

Summary: The study found that mercury levels in lionfish increase with size, vary by location and sex, but overall, the mercury levels in lionfish are lower than other commonly consumed marine fishes, posing a low risk to consumption.

Summary: Coral reefs, known as tropical rainforests in the ocean, have a rich diversity of fish species. China has 2855 species of coral reef fishes, which can be categorized into nearshore and offshore. The diversity of coral reef fish species has a significant positive correlation with coral species diversity.

Summary: This passage discusses the study of cannibalism in Bythotrephes cederstromii, demonstrating and quantifying the cannibalism rates through laboratory experiments. The results suggest that cannibalism could be an important food source during certain periods of the year and in particular places.

Summary: The evolution of bright warning colors in nontoxic animals is often attributed to mimicry of toxic species. By pulling snake-shaped models through the water and observing the response of predatory fish, the study found that banded color patterns reduce the vulnerability of non-venomous marine snakes to predation.

Summary: Interspecific interactions play a vital role in shaping wildlife populations and communities. However, there are limited assessments of such interactions, especially in aquatic systems over broad spatial and temporal scales. This study used acoustic telemetry to investigate the predator-prey dynamics between Atlantic tarpon and permit and two predator sharks, great hammerhead and bull sharks, in the coastal region of the Florida Keys over a 3-year period. The results show heterogeneous predation risk and elevated encounter rates at specific locations and times.

Summary: The discovery of fossils in Mayan tombs has fundamentally altered our understanding of the earliest origins of coral reef fishes and reconciled the conflict between fossil and phylogenetic evidence. These fossils indicate that the origins of reef fishes can be traced back to Mexico, just 3 million years after an asteroid impact, and reveal new insights into their early biogeography.

Summary: The settlement of coral larvae is crucial for the success and longevity of coral reefs. However, the proliferation of Ramicrusta sp., a red-brown encrusting alga, poses a serious threat to coral recruitment by overgrowing corals and causing high mortality rates in larvae compared to crustose coralline algae (CCA) and control groups.

Summary: This study investigates the expression of visual pigment gene (opsin) in coral reef fishes and finds that algivorous species with orange/red colors exhibit high expression of long-wavelength-sensitive (lws) opsin. This enhances their ability to detect algae and orange/red-colored conspecifics, possibly enabling social signalling.

Summary: This study assessed the function of artificial reefs as alternative habitats for two common reef-associated predatory fishes. The results suggested that artificial reefs have strong ecological adaptability for predatory fishes, but prey availability differs from natural reefs, leading to different degrees of resource partitioning between the two reef types.
