Dolphins of many species release bursts pulses when they are excited or angry, and burst pulses are thought to convey information about a dolphin's emotional state.
The discovery of spindle cells in the brains of some whale and dolphin species provides good supporting evidence that these species may be capable of experiencing complex emotions such as empathy and indeed that this emotion may provide an important evolutionary advantage for these highly social species.
In general, dolphins make two kinds of sounds, “whistles” and “clicks” (listen to the false killer whales on this page). Clicks are used to sense their surroundings through echolocation, while they use whistles to communicate with other members of their species and very likely, with other species too.
There are dozens of photos and YouTube videos of grieflike behavior in dolphins: Some mothers have been seen carrying their dead infants in their mouths or on their backs for a week or longer, even as the body decomposes; a couple adult males have also been seen holding dead calves in their mouths.
As a child, you may remember squealing and screaming when you were excited about something. It turns out that humans aren't the only species that gets noisy when they're happy: New research shows that whales and dolphins “squeal with delight” to express glee, too.
Dolphins are very tactile and social. They show affection for each other by rubbing each other with their pectoral fins. When actual mating occurs, it is completed very quickly, with the two dolphins swimming belly-to-belly during intercourse.
Perhaps their mating behaviour does not point to what we typically perceive as “love”, but the indication of dolphin friendship and affection certainly demonstrates a capacity for the emotion to some degree. In several surprising instances, dolphins have also shown loving emotions towards humans.
One physical indicator of stress is elevated cortisol levels in blood work, which is commonly seen in lab results for captive dolphins. Much like in humans, dolphins release this hormone when under stressful conditions.
Most scientists agree that empathy is an evolutionary advantage reserved for the smartest mammals, including great apes, dolphins and humans.
Dolphins aren't smiling.
But a dolphin's toothy grin is not an expression of joy – this is simply an anatomical anomaly. Since dolphins always appear happy to us, the dolphin entertainment industry takes advantage of this misinterpretation to cover up their cruelty. The truth is: dolphins smile even when they're dead.
“The clitoris of dolphins has well-developed erectile spaces, is highly sensitive to tactile stimulation, and is likely functional,” the study notes. The animals do experience pleasure when having sex, due to their “large” clitorises.
Like happy kids, whales and dolphins often squeal with delight when something good comes along. Continue reading → Dolphins and whales squeal after pleasant moments, researchers noticed long ago, such as receiving a tasty fish treat. A new study supports that these happy sounds are genuine expressions of delight.
Dolphins often show aggression by raking — scratching one another with their teeth, leaving superficial lacerations that soon heal. Traces of light parallel stripes remain on the dolphin's skin. These marks have been seen in virtually all dolphin species.
Dolphin Depression Syndrome
There is plenty of evidence suggesting that dolphins show symptoms of being depressed in captivity. Dolphins can engage in stereotypic behaviors, ranging from repetitive motions or unnatural behaviors that are only seen in captive individuals.
Like humans, female bottlenose dolphins experience sexual pleasure through their clitoris, according to new study in Current Biology.
Whale and dolphin brains contain specialized brain cells called spindle neurons. These are associated with advanced abilities such as recognising, remembering, reasoning, communicating, perceiving, adapting to change, problem-solving and understanding. So it seems they are deep thinkers!
Elephants are considered to be one of the world's most empathic species. In my last blog, I wrote about how African elephants grieve and mourn their dead, proving that they're truly empathetic, social animals.
The science makes one fact undeniably clear: wild dolphins of some species are noted for seeking out social encounters with humans. The phenomenon of lone sociable dolphins – for whom human contact appears to substitute for the company of their own kind – is documented extensively in the scientific literature.

Dolphins are capable of learning skills based on human instruction and expressing certain desires. Any dolphin trainer will tell you that dolphins and humans can indeed communicate in a limited in fashion. This "limited fashion" involves learning certain trained tasks and expressing the desire for things such as food.
The ancient Greeks told stories of dolphins protecting sailors, and it even happened on an episode of Flipper. It isn't surprising that people are fascinated by this idea. Unfortunately, there just isn't any reliable evidence that it's true.
Dolphins appear to have a special affection for pregnant women.
It so simple, you need to approach the dolphin, hold the face and look into the dolphin's eyes. Then pucker up and kiss the dolphin on the mouth or general area. It will be a kiss you won't forget and make sure you get a photo of this so you won't forget it.
Swimming – Dolphins love to swim a lot. They are capable of performing the most bizarre tricks like jumping up high into the air and then diving into the water like a corkscrew.
Dolphins are not monogamous animals and do not typically mate for life. Atlantic bottlenose dolphins live in what are called fission-fusion societies, where pods are constantly changing in size and numbers. Some believe bonds between males are the strongest and most enduring in bottlenose dolphin societies.
