Although harvest of Octopus maya (Mexican four-eyed octopus) is one of the most important fisheries in the Yucatan Peninsula, little is known about the parasites of these cephalopods and how they affect host physiological processes. We analyzed the spatio-temporal variation of infection of O. maya by the cestode larva Prochristianella sp.

The Yucatan coastal zone is an area that contributes to many anthropogenic activities resulting in substantial contamination (metals, pesticides) in aquatic organisms. The dolphin is an excellent sentinel animal used in studying contamination in this area. Some substances found in dolphins have been identified as toxic causing alterations in the properties of membranes and produce lipid peroxidation especially heavy metals.

Invasive fungal infections represent a global health threat. They are associated with high mortality and morbidity rates, partly due to the ineffectiveness of the available antifungal agents. The rampant increase in infections recalcitrant to the current antifungals has worsened this scenario and made the discovery of new and more effective antifungals a pressing health issue.

Article Synopsis
  • * The study aimed to analyze the presence of trace metals in dolphin blubber and understand their relationship with lipid composition using advanced analytical techniques.
  • * Findings revealed toxic elements like cadmium and arsenic, which correlated with various lipid types, indicating potential physiological impacts on dolphins and highlighting the risks posed by human activities in coastal areas.

Article Synopsis
  • The common bottlenose dolphin is an apex predator in marine environments, making them vital for monitoring coastal ecosystem health due to their ability to accumulate environmental contaminants.
  • Using proton nuclear magnetic resonance spectroscopy, researchers identified 51 metabolites across 74 metabolic pathways in the skin and blubber of stranded dolphins, revealing significant differences in metabolism between the two tissues.
  • Results highlight that blubber is associated with fatty acid metabolism and fat synthesis, while skin is linked to gluconeogenesis, suggesting different metabolic roles for these tissues in the dolphins' physiology.
