Exploratory Behavior

Improved Essays
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, …show more content…
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

    Crayfish are freshwater crustaceans that use their claws called chelipeds,for warning off predators. When frightened, these crayfish lift their chelipeds to make threatening gestures, all while moving backwards or staying still. We examined how long it would take for crayfish to calm down once removed from the water and if the temperature had any influence to this observation. To do this, we placed two crayfishes in room temperature water and another two in colder water for an interval of five minutes and again for ten minutes. Once the time was up,we measured how long it took for the crayfish to lower their claws.…

    The Pacific Northwest tree octopus (Octopus paxarbolis) can be found in the temperate rainforests of the Olympic Peninsula on the west coast of North America. Their habitat lies on the Eastern side of the Olympic mountain range, adjacent to Hood Canal. These solitary cephalopods reach an average size (measured from arm-tip to mantle-tip,) of 30-33 cm. Unlike most other cephalopods, tree octopuses are amphibious, spending only their early life and the period of their mating season in their ancestral aquatic environment. Because of the moistness of the rainforests and specialized skin adaptations, they are able to keep from becoming desiccated for prolonged periods of time, but given the chance they would prefer resting in pooled water.…

    The researcher, examined the data in detail and found the patterns underlying the summary statistics were not obviously unreasonable. Furthermore, the survey responses revealed male participants are no more likely to oppose a female youth’s decision to obtain an abortion than a woman. But, exploratory analysis, aimed to answer (a) whether a subject’s annual income would change their personal opinion of a female youth victim’s right to obtain an abortion without parental or court consent, and (b) would the subject’s level of education alter their viewpoint of consent in comparison to the other survey participants. Does a subject’s annual income influence their support of a youth female rape victim obtaining an abortion without parental or court consent? To begin with, the research results showed all participants, no matter gender or annual income bracket, disagreed with the notion youth female rape victims needed to obtain court consent to have an abortion.…

    If it was established that other animals (excluding apes) possess MSR, it would prove that humans and apes aren’t the only species to perceive their own identity. While there have been promising results regarding dolphins’ ability to display MSR, prior to this experiment, the results have remained inconclusive. This uncertainty is based on problems with control methods capable of obtaining solid results in an animal that isn’t able to display self-recognition by touching a marked part of its body. If dolphins are able to exhibit MSR, this information may prove beneficial in helping to explain evolution and would be a huge breakthrough in determining if MSR capacity is a result…

    Being that over 90% of Earth's oceans left untouched, it is impressively fascinating to observe the mysterious forms of life that science has uncovered in regards to deep sea organisms. With an ambient environment that is unlike any other, organisms who span the ocean floor are amongst the most diverse populations of animals known to man. Dr. Goffredi's memorable talk presented a compelling call for exploration, as she details the diversity and mystery of deep sea organisms. The two main organisms discussed in her talk were the Kiwa hirsuta (affectionately named the “yeti crab”), and the Osedax rubiplumus. Dr. Goffredi places importance on the idea that symbiosis equates biological innovation.…

    The deep ocean is considered an extreme environment because of the low temperatures, high pressures, lack of oxygen and no sunlight. These conditions have caused the organisms which live there to evolve, often through unusual and unique adaptations, so they can live, reproduce, and thrive. An extreme environment is a place where humans normally do not live or could die there. There are organisms caused extremophiles that live there and are so well-adapted that they readily grow and multiply in order to survive. An example of an extremophile which lives in the deep ocean is the Anglerfish.…
