“…In such cases, thermally stressed females spawn, even when embryos are at thermal risk. However, the results obtained in the laboratory have demonstrated that in temperatures higher than 27°C, the octopus spawn is inhibited, suggesting that other more complex processes regulate O. maya reproduction during thermal stress ( Di Cosmo and Polese, 2014 ; Domínguez-Estrada et al, 2022 ; Juárez et al, 2015 , 2019 ; Ventura-López et al, 2022 ). Considering the previous results, a second question arises: Could the strength of the oxygen flow pumped from the systemic heart be the signal to the brain that triggers the complex regulatory mechanisms directed to preserve the embryos’ integrity, inhibiting spawning at high temperatures?…”

“…The results obtained in the present study show that at 26°C cardiac mitochondria of this acclimation group (26°C) have the highest State 3 respiration, indicating that this temperature is where the cardiac activity is the highest (maximum activity of the proton transport chain and ATP production) and consequently for the transport of oxygen to the rest of tissues, including the reproductive ones. Juárez et al (2015 , 2022 ), Domínguez-Estrada et al (2022) , and Ventura-López et al (2022) studied gene expression in O. maya females exposed to different temperatures. These authors found that in the interval from 24 to 26°C many genes are involved in biochemical processes that ensure the sperm maintenance and egg fertilization success, upregulating in O. maya brain and oviductal gland, probably due to high oxygen availability.…”

“…In a study conducted on O. mimus embryos, Olivares et al (2019) hypothesized that negative parental influence on offspring is related to ROS transferred from females to oocytes during oogenesis, causing an ulterior overload for embryos. In this regard, during spawning, female optic glands (located in the brain) focus on maintaining balance between energy and ROS production (Ventura et al, 2022), but high temperatures drastically affect this process (Domínguez et al, 2022). Moreover, at high temperatures, the optic gland in females up-regulates the expression of genes related to stress response and production of stress molecules like corticosterone (Dominguez-Estrada et al, 2022), which may alter embryonic development (Hayward and Wingfield, 2004;Vagnerová et al, 2008).…”

“…During the reproductive phase, females use their energy reserves for parental care (Lin et al, 2019; Roumbedakis et al, 2017; Ventura-López et al, 2022). Biological processes like oxidation-reduction process, respiratory electron transport chain and precursor metabolite and energy generation are conspicuous during spawning in this octopus species (Ventura-López et al, 2022; Meza-Buendia et al, 2021). However, thermally stressed females showed a lower metabolic scope than females maintained in thermally optimal conditions.…”

“…An example of the latter is the case of O. Maya, a species of octopus endemic to the Yucatan Peninsula, Mexico, whose maintenance conditions, from the egg stage to the adult stage, have been widely described [14][15][16]. This allows O. Maya, along with other species such as O. insularis [17], O. minor [18] and O. Vulgaris [19] to be considered laboratory animals for physiological, behavioral, and evolutionary studies [20]. As part of these studies, it is crucial to know as much as possible about general anatomy and, particularly in the case of neurobiology, the anatomy of the nervous system.…”
