The decrease in ammonia being excreted is also related to the metabolism of the octopus due to its need to spend more energy as the temperature increases. Octopus vulgaris will reduce the amount of ammonia excreted in order to use the excess solutes that it would have otherwise excreted due to the increased metabolic rate.
Ammonia excretion diminishes in octopuses, including Octopus vulgaris, due to elevated energy needs and increased metabolic rates at higher temperatures. To handle the excess solutes that would have been excreted, they decrease ammonia release.
