Intra-egg oxygen dissolved in Octopus maya embryos

Those data show, for the first time, oxygen concentration levels in the perivitelline liquid of Octopus maya embryos. Data are shown as a percentage of oxygen saturation, measured at 24°C, using a Needle-type oxygen microsensor (Loligo Systems, Denmark). The sensor was placed in an automated micromanipulator (PreSense, Germany), and the eggs were placed in a supporting device at 38° of inclination. In such form, the sensor was inserted in the perivitelline liquid, registering the oxygen dissolved inside the eggs. The final oxygen level was recorded between one and three min after the sensor insertion. Data of oxygen dissolved during embryo development were grouped as blastulation, organogenesis, activation, and growth phases. A negative power curve was constructed for the relationship between oxygen dissolved in the perivitelline liquid and embryo development

Data of Mitochondrial respirometric data of adult males of Octopus maya: supporting the method to evaluate heart metabolic activity

Mitochondrial respirometry is key to understanding how environmental factors model energetic cellular processes. Until now, no reports have shown temperature effects and other environmental variables on cephalopod mitochondria activity because of the lack of a method to evaluate mitochondrial respiratory parameters on those groups of species. In this sense and for the first time, it showed the mitochondrial respirometry data of adult Octopus maya’s heart. Following the protocol is illustrated a step-by-step procedure to get the corresponding respiratory parameters.

Data of the study of Maternal temperature stress modulates acclimation and thermal biology in Octopus maya (Cephalopoda: Octopodidae) juvenile progeny

These data shows the effects of temperature and exposure time on octopus juveniles  obtained from thermal-stressed (30°C) and non-stressed (24°C) females when exposed to optimal (25°C) and high temperatures (30°C) for 20 and 30 days, respectively. Data of  survival, and oxygen consumption (MR) were obtained, also in routine (RMR) and resting conditions (SMR). The high metabolic rate (HMR) was used to obtain the thermal metabolic scope (TMS) That was defined as: TMS = HMR - SMR Data on the  antioxidant defense enzymes and radical oxygen species (ROS) were used to evaluate if transgenerational effect of temperature provoked changes in the hability of juveniles to neutralize ROS.

Raw data of Octopus maya embryos along the development: wet weight, oxygen consumption, antioxidant defence mechanisms and oxidative damage.

Raw data on oxygen consumption and antioxidant defense mechanisms of Octopus maya embryos were maintained in laboratory conditions at 24°C. Those data were obtained during the embryo development. The antioxidant defense mechanisms and oxidant damage were also obtained from the ovary and the un-spawned eggs, allowing to us known how is the oxidant damage translated from the females to embryos in this octopus species.
