One of the major behavioral adaptations of marine mammals is their ability to swim and dive. Pinnipedsswim by paddling their flippers while sirenians and cetaceans move their tails or flukes up and down.
Some marine mammals can swim at relatively high speeds.Sea lions swim up to 35 kph and orcas can reach 50 kph . The fastest marine mammal, however, is the common dolphin, which reaches speeds up to 64 kph . While swimming, these animals take very quick breaths. For example, the fin whale can empty and refill its huge lungs in less than 2 seconds. During dives the larynx and esophagus close automatically when marine mammals open their mouths to catch prey. Oxygen is stored in hemoglobin in the blood and in myoglobin in the muscles. The lungs are also collapsible so that air is pushed into the windpipe preventing excess nitrogen from being absorbed into the tissues. Decreasing pressure can cause excess nitrogen to expand in the tissues as animals ascend to shallower depths, which can lead todecompression sickness aka "the bends." Bradycardia, the reduction of heart rate by 10 to 20%, also takes place to aid with slowing respiration during dives and the blood flow to non-essential body parts. These adaptations allow sea otters to stay submerged for 4 to 5 minutes and dive to depths up to 55 m . Pinnipeds can often stay down for 30 minutes and reach average depths of 150-250 m . One marine mammal with exceptional diving skills is the Weddell seal, which can stay submerged for at least 73 minutes at a time at depths up to 600 m . The length and depth of whale dives depends on the species. Baleen whales feed on plankton near the surface of the water and have no need to dive deeply so they are rarely seen diving deeper than 100 m . Toothed whales seek larger prey at deeper depths and some can stay down for hours at depths of up to 2,250 m .
Marine mammals are often very social animals. Dolphins travel in pods (schools) and catch rides on the bow waves of boats. Marine mammals are also known to help each other when one member of the group is injured. There have been accounts of members of a pod refusing to leave the wounded or dying, a trait often exploited by whalers. Cetaceans (whales and dolphins) often hunt together, often with one leading the pod to act as a scout when entering unfamiliar territory. This close knit socialization is thought to be a factor in some whale strandings when a pod follows one or more members of the group that have become disoriented due to storm, illness, or injury.
Many marine mammals also participate in yearly migrations, either in groups or individually. Toothed whales are an exception and only move about in search of food, but some baleen whales (such as gray whales) embark on extremely long migrations, moving from tropical breeding grounds in winter to feeding areas in colder waters during the summer.

What are 2 behavioral adaptations?
Behavioral Adaptations:Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.A cat learns to lean on its haunches to keep quiet when huntingA giraffe's long neck is a physical adaptationAn elephant's trunk to suck in water and blow it out over its body to keep cool.
What a behavioral adaptation is?
Behaviour adaptation is the response an animal gives to environmental stimulus and a change in that behaviour. This change is often for the health of the animal. An example of this is found in sheep. If sheep are put in a paddock near a road, and a car drives past they will immediately run in the opposite direction. This obviously wastes a lot of energy and takes up precious eating time, gradually over time they realise there is no danger from the car passing on the road and no longer run away. Their behaviour has adapted. This is obviously a simple example but can be applied to any animal in nature.Behavioral adaptations are the things animals do to survive. Like bird calls or migrating are forms of adapting. When certain species are born they have to watch their parents or others surrounding them to understand what they have to do to survive. They have to learn to cope with the weather, enemies, and environment in a "suvival of the fittest" way.Here are some examples of Behavioral and Structural Adaptations:Behavioral Adaptations:Birds---migrate/fly south in the winterBears---hibernate in the winterPossums---play "dead" to avoid predatorsDesert animals---(1) nocturnal/inactive during the daytime and (2) below-ground dwellings to avoid harsh raysStructural Adaptations:Duck---webbed feetFish---gillsGiraffe---long neckBeaver---large, pointed teethWhale---blubberCactus---shallow rootsSnake---flexible jawAn adaptation is any trait that changes to better suit the organism for its environment. Adaptations are genetically-based and can be passed on from generation to generation. Behavioral adaptations are those adaptations that have a behavioral component to them.Behavioral adaptapations are adaptations like a sea turtle going into the ocean. Insticts and learned behaviors are behavioral adaptations.basically what an animal does to survive in the habitatBehavioral adaptations are different to physical adaptations because behavioral adaptations are (like the name suggests) changes in behavior that increase an organisms fitness/survival, whereas physical adaptations are changes to an organisms body structures. The two are not exclusive, you can have behavioral AND physical solutions to the same problem.Best illustrated with some examples: heat and heat regulation; if an organism gets too hot it can move out of the sun and into shade, that is a behavioral adaptation. Or, over millions of years it can evolve mechanisms of cooling, humans do it by sweating, dogs pant, birds fluttering their throat muscles (called "gular fluttering" but it is essentially panting!)Another example: deer respond to the presence of a predator by running away, or joining together in groups (herds) - these are changes to its behaviour that decrease its chances of getting eaten. Physical adaptations to not getting eaten would be having highly developed leg muscles for quick acceleration and running away, or maybe camouflage colouration, or confusing colouration (such as the stripes on zebras, which make it hard to see one individual from another when they are in a group)

What are the adaptation of the lemur?
Even as a proffessor of anatomy at Sydney University, I have extensively studied a broad range of animals, including the colugo (flying lemur), however i only know of three adaptations. 2 of which are structural and one behavioral adaptation which could also be physiological. The two structural adaptations of the colugo of South East Asia are its large eyes which allow it to see and hunt more efficiently at night and the membrane (patagium) that goes around its whole body allowing it to glide from tree to tree and hunt more efficiently. The behavioral adaptation is that the colugo is nocturnal, yet this could possibly even be a physiological adaptation on the colugo, not a change in its behaviour in response to different foods available in different times throughout the day and night. If anyone has 1 more behavioral adaptation it would really help me out as a student asked me the same thing and I would prefer to not look a fool. So if anyone knows another behavioral adaptation of the colugo (flying lemur) of South-East Asia please post it OMG i cant belive that coolieo Not sure about behavioral but camouflage counts as an adaptation, right? ?? ^_^If you are a professor of anatomy, shouldn't you be reading primary literature to determine the behavioral / structural / physiological adaptations of mammals?
