“…These fish can accumulate heavy metals in their tissues over time through the ingestion of contaminated food and direct exposure to polluted water. This progressive accumulation of heavy metals in the tissues of S. cretense allows for the assessment of chronic exposure of marine organisms to pollution and, therefore, the estimation of potential impacts on the health of the biological community and potentially human health [81][82][83][84]. The selection of S. cretense as a bioindicator is based on its ability to reflect the variability in heavy metal levels within different marine environments of the Canary Islands.…”

This study investigates the impact of varying environmental conditions on the metal composition within the tissues of Sparisoma cretense, contributing to the understanding necessary to offer scientifically sound advice regarding the health status of this species. This knowledge extends beyond fishery production, encompassing implications for food security. The data span the years 2022 and 2023, encompassing both cold and warm climatic seasons. The concentrations of various metals, such as Al, Zn, Cd, Pb, Fe, and Cu, exhibited noteworthy variations across the islands, with significant increases recorded in 2023, particularly during the warm season. The intricate interplay between multiple factors shaped the availability of the analyzed elements in S. cretense. Factors such as rising temperatures during the warm season increased biological activity in marine ecosystems, seasonal fluctuations in weather conditions, water quality, and anthropogenic influences, all contributing to the observed variations in metal concentrations. Additionally, the geological composition of each island and the patterns of marine currents and sediment transport play pivotal roles in these differences. Comprehensive scientific research, monitoring, and environmental surveillance are essential for a holistic understanding of this variability and providing valuable insights for the conservation and management of marine ecosystems in the Canary archipelago.

“…In our study, the metal ranking showing accumulation in muscle tissue was calculated as Fe> Al> Cr> Cu> Cd. Escobar-Chicho et al (2019) found the levels of metal accumulation in different tissues of an anemone (Paraphelliactis pabista) in the Gulf of California Guaymas basin at 501.15 mg/kg, 132.35 mg/kg, 9.94 mg/kg, 0.24 mg/kg, 3.21 mg/kg, 645.79 mg/kg, 136.28 mg/kg, 23.46 mg/kg, 8.86 mg/kg (dry weight) Fe, Zn, Cu, Co, Ni, Al, Mn, Pb, and Cr, respectively. When the accumulation levels of A. equina individuals distributed in the bay were compared, it was determined that Zn, Cu, Co, Ni, Mn, Cr levels were higher than other studies, whereas Fe, Al, Pb accumulation levels were lower than other studies.…”

The purpose of this study was to determine the accumulation levels of ten metals (Fe, Zn, Cd, Cu, Co, Ni, Al, Mn, Pb, and Cr) in the muscle tissues of Actina equina indvduals. A total of 120 individuals of A. equina were collected at six different stations in İskenderun Bay in spring 2013. The accumulation levels of heavy metals in the tissues were found to vary significantly among stations. The mean concentrations of Fe were the highest at Samandağ station (105.11 ± 74.28 mg/kg) whereas the lowest average value of Co (0.84 ± 0.10 mg/kg) was obtained at Dörtyol station. Heavy metal concentratıons in muscle tissue of A. equina were ordered as Fe>Zn>Mn>Al>Cr>Cu>Pb>Ni>Cd>Co, respectively. This study is the first detailed bioaccumulation study conducted with A. equina in İskenderun Bay.

“…At deep-sea hydrothermal vents, many dissolved metal ions, which included iron (Fe 2+ ), zinc (Zn 2+ ), manganese (Mn 2+ ), cadmium (Cd 2+ ), cobalt (Co 2+ ), and copper (Cu 2+ ), are carried by the high-temperature plumes of vents and settle around them (4,7). Previous studies have demonstrated that invertebrates residing in proximity to hydrothermal vents accumulate enormous amounts of metal ions within their diverse tissues (8,9), but they exhibit no visible signs of stress or malformations (10). This suggests the potential presence of specialized metal ion detoxification strategies in these organisms.…”

Hydrothermal vent habitats are characterized by high hydrostatic pressure, darkness, and the continuous release of toxic metal ions into the surrounding environment where sea anemones and other invertebrates thrive. Nevertheless, the understanding of metazoan metal ion tolerances and environmental adaptations remains limited. We assembled a chromosome-level genome for the vent sea anemone, Alvinactis idsseensis sp. nov. Comparative genomic analyses revealed gene family expansions and gene innovations in A. idsseensis sp. nov. as a response to high concentrations of metal ions. Impressively, the metal tolerance proteins MTPs is a unique evolutionary response to the high concentrations of Fe 2+ and Mn 2+ present in the environments of these anemones. We also found genes associated with high concentrations of polyunsaturated fatty acids that may respond to high hydrostatic pressure and found sensory and circadian rhythm–regulated genes that were essential for adaptations to darkness. Overall, our results provide insights into metazoan adaptation to metal ions, high pressure, and darkness in hydrothermal vents.
