A female bottlenose dolphin performing with her trainer. They are considered one of the most intelligent cetaceans. Cetacean intelligence is the overall intelligence and derived cognitive ability of aquatic mammals belonging in the infraorder Cetacea (cetaceans), including baleen whales, porpoises, and dolphins.
You can see dolphins about 80-90% of the time on a dolphin sightseeing tour. According to Richardson, the best time to go earlier in the day to see dolphins, because the ocean waves will be calmer.
However, at higher speeds dolphins and porpoises will seek out the pressure wave and its maximum energy zone in order to ride the wave by holding their flukes in a fixed plane, with only minor adjustments for repositioning. [19] Wave-riding reduces the energetic cost of swimming to the dolphin, even when compared to slower swimming speeds. [19]
[57]: 233–235 [56] Dusky dolphins can also benefit from encounters with boats by riding the waves produced by them (bow-riding), which saves energy while travelling. [60] The effect of mussel farming on dusky dolphins has been studied in Admiralty Bay. Apparently, dolphins rarely enter farms, and when they do, they quickly swim through them. [61]
About 400 people help count the population each year. ... They’re all watching with one goal in mind: to tally the number of dolphins cruising local waters. It’s the annual dolphin count, and ...
Encounter between a solitary wild dolphin and human children in 1967. Educational anthropologist Dr. Betsy Smith of Florida International University is usually credited with starting the first line of research into dolphin-assisted therapy in 1971, building on earlier research by American neuroscientist Dr. John Lilly on interspecies communication between dolphins and humans in the 1950s.

Marmontel said most of the dolphins that perished last year were in Lake Tefé, a 45-km-wide (27-mile) expanse of water where the dolphins like to be located, just off the Solimoes River.
The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...
