A sperm whale is the largest of all the toothed whales, and the largest toothed predator. Reaching lengths of up to 67 ft. long the.The sperm whale also happens to have the largest brain and cerebrum of any known mammal in existence today.In fact the sperm whales brain weighs 5 times that of a humans brain!Although brain size has previously been used to correlate intelligence among various animal species recent research has shown that brain size does not always equal high intelligence, so the sperm whales brain size cannot be used as the only determining factor of intelligence.However despite whether or not their brain size has an impact on their intelligence the cetacean family overall has displayed a high level of intelligence as a species.For those of you who aren’t familiar with cetaceans the cetacean species includes all species of whale.Most of what we know about cetacean intelligence has been gathered from research done on dolphins.Unfortunately most whale species are too large in nature to perform similar tests on, so intelligence gathering is often limited to observations of large whales and tests performed on smaller cetacean species.Among the dolphin population researchers and trainers have performed various tests on their ability to learn comprehensive tasks, problem solve and respond to various commands.Dolphins have also shown the ability self recognize and observe markings placed on their body when facing a mirror; a characteristic that is common among only a few highly intelligent species.In fact dolphins have even been trained by the military to locate underwater mines and military personnel lost at sea.Because dolphins and whales (such as the sperm whale) possess many of the same abilities and cognitive skills it is likely that many of these same mental strengths also exist among the sperm whale species.To help the sperm whale navigate the ocean and survive these marine mammals are equipped with a pair of large retractable eyes and an enlarged auditory system to help find their way around.And because sound travels 4 times faster in water than it does on land having excellent hearing can be essential to their survival.Furthermore these whales possess excellent echolocation abilities and some scientists believe the sperm whales large head and the waxy substance that is created from the.Echolocation allows these marine mammals to locate prey and navigate the ocean in complete darkness, which is especially useful for the sperm whale since they often hunt for food in the dark.Overall sperm whales are considered intelligent.For a long time brain size was correlated directly with intelligence and even though considerably more is known about the brain then in the past intelligence and brain size continues to be a debatable topic among researchers and scientists.Part of this continuing debate has to do with observations from different tests and case studies.In one study a group of city mice that were compared to a group of country mice and showed that mice that lived in the city had larger brains than those that lived in the city which was believed to be a clear indicator of increased intelligence among city dwelling animals that dealt with higher levels of cognitive stress, however observations of other mammals showed little or no increase in brain size despite living in city/urban environments.Interestingly a number of other animal species showed larger brain sizes in rural areas than those living in city environments which challenged the nature vs nurture theory and negated the idea that animals living in a city area are more intelligent than those in rural areas.The reason this research was considered compelling at first is that there was a belief that animals that lived in areas where more intelligence is required for survival would grow larger brains to deal with the additional cognitive needs of living in such an area, however this idea as well as others have since come under scrutiny as more compelling arguments and tests have been conducted.Furthermore while animals with larger brains such as elephants and whales show significant capacities for self recognition, problem solving, language, culture and family many researchers believe that they still have less cognitive capacities and intelligence than humans.While there is no argument that these animals are intelligent there are regular arguments in regards to how intelligent they are and whether or not they are as intelligent as humans.Rather than basing intelligence on brain size alone some researchers believe that a better correlate of intelligence or cognitive skill should be based on the size of specific parts of the brain and how they compare to the rest of the brain and overall body size.Areas such as the frontal lobe, temporal lobe, parietal lobe and visual/auditory systems among others may be measured separately to determine an animals level of performance related to that specif brain function.Studies among children and adults show that when one part of the brain has abnormal growth/reduced size it can alter the brains ability to function and either enhance or reduce specific functions associated with that part of the brain.This can include sensory perception, emotional responses and capacity, motor skills, problem solving and memory among other mental functions.Individuals that suffer from mental disorders often show impairments in the specific regions of the brain where that specific skill is developed or used.By measuring the size of specific regions of the brain researchers may have a better understanding of how a specific function performs when compared to other species with smaller/larger regions.In order to better understand the brain and how it functions tests are now often performed using MRI scans during specific activities in order to measure the brains response to certain impulses.Humans and monkeys are often the subject of MRI tests as their size and cognitive capacities are often easy to compare and study.From research that has been performed on primate and other animals some researchers believe that brain size, the size of the frontal lobes, gray and white matter and overall thickness of the cortex may correlate with social bonding, culture and interaction with other animals.Under this theory animals with larger and more developed brains can deal with a more complex social society and the stresses associated with bonding, culture development and social interaction rather.Under this theory social intelligence may be associated with brain size and development as complex social interactions and culture tend to be the result of higher intelligence.This idea also suggests that brain size is correlated more with social development than motor skills.If this theory is correct than it can be concluded that brain size and development may have some correlation with intelligence, social bonding and culture development among various animal species, however this correlation only accounts for a portion of the animals level of intelligence as animals with smaller but more developed brains may show equal or higher levels of overall intelligence than those with larger brains.When it comes to animals of the same species brain size appears to be less of a correlate of intelligence as humans of various brain sizes have shown extremely small correlations of intelligence relative to the size of their brain when compared to that of other human beings.We use cookies to ensure that we give you the best experience on our website.
