Results Yasumuro and Ikeda (2011) discovered statistically significant differences between the poor and enriched environments through exploratory behavior, various body patterns, and reactions to stimulus. The duration of exploratory behavior witnessed in the octopuses in the poor environment were notably less frequent than the standard or enriched environments, while the enriched environments displayed the most exploration of all three environments. Variations of exploratory behavior were seen on different days within the environments. For example, the second and third days of the experiment showed gradual increase exploratory behavior in the poor and standard environments while decreasing in the enriched environment on the second day. However,

The Uniform White Phase (UWP) and Chronic General Mottle (CGM) body patterns were witnessed somewhat similarly in all three environments. However, variations of the UWP were significantly different in the environments while active or inactive. The octopuses in the poor environment displayed UWP more often while active; contrastingly, the standard and enriched environments displayed UWP frequently while inactive. Notable variations were observed with the Acute Mottle (AM) body pattern, which was displayed drastically more in the poor environment than the standard or enriched environments. This body pattern was displayed frequently in the poor environment while the octopuses were inactive. Additionally, the octopuses in the poor environments displayed significantly less Uniform Darkening (UD) and Dark Head (DH) than the standard and enriched …show more content…
They also noted that the decrease of exploratory behavior in all three environments may be due to lack of live prey and recommended more stimuli and live prey for captive octopuses to prevent abnormally recurrent lethargy. Additionally, it was noted that octopuses need objects for sensory stimulus and that more objects promote more exploration. Enriched environments may also aid in commercial benefits, namely reproduction and rearing. Conservation and reintroduction programs may increase survival after release. The previously mentioned scientists also believe aquariums will benefit from the findings, by allowing spectators to witness cephalopod’s intelligent capabilities. Clearly, humane practices are necessary for these clever invertebrates, just as they are for the
