Cutaneous Respiration in Octopus Vulgaris
The skin of Octopus vulgaris consumes considerable quantities of oxygen in vitro, averaging 4.55×10−5±1.80×10−5 ml mm−2 h−1 (mean ± S.D.), if a flow is maintained over the skin sample (N=32). The consumption is higher still in vivo, 11.36×10−5±2.73×10−5 ml mm−2 h−1 (N=8), suggesting an additional net import of oxygen through the skin when the blood system is intact. If a substantial boundary la...
متن کاملObservational Learning in Octopus vulgaris.
Untrained Octopus vulgaris (observers) were allowed to watch conditioned Octopus(demonstrators) perform the task of selecting one of two objects that were presented simultaneously and differed only in color. After being placed in isolation, the observers, in a similar test, consistently selected the same object as did the demonstrators. This learning by observation occurred irrespective of the ...
متن کاملInfiltrated plaques resulting from an injury caused by the common octopus (Octopus vulgaris): a case report
Several species of octopus are considered venomous due to toxins present in the glands connected to their “beak”, which may be associated with hunt and kill of prey. Herein, we report an accident involving a common octopus (Octopus vulgaris) that injured an instructor during a practical biology lesson and provoked an inflamed infiltrated plaque on the hand of the victim. The lesion was present ...
متن کاملAccumulation of mercury in the tissues of the common octopus Octopus vulgaris (L.) in two localities on the Portuguese coast.
Mercury concentrations were measured in tissues of 12 individuals of Octopus vulgaris, captured by the commercial fishery at two points along the Portuguese coast, Viana do Castelo and Cascais, in spring 2002. Concentrations were determined in six tissues (digestive gland, branchial hearts, gills, mantle, arms, and gonads). Correlations between mercury concentrations in different tissues were e...
متن کاملMultiple paternity in the common octopus Octopus vulgaris (Cuvier, 1797), as revealed by microsatellite DNA analysis
Two microsatellite DNA markers developed for the common octopus, Octopus vulgaris, were used to determine genotypes of four brooding female octopuses and 11 embryos sampled from their respective clutches, in order to confirm the multiple paternity hypothesis within this species. Two well-known reproductive behavioural patterns are apparently conflicting in mating outcome: the often-observed mul...
