Remember that dolphins are protected by the Marine Mammal Protection Act. Email reports of sightings to David Anderson or call Cascadia’s office at 36. These can help identify individual animals and to monitor their overall body condition. I know you're playing in your head that stock dolphin sound that pretty much everyone's heard before. Pictures and videos are appreciated, especially if they are in focus and have enough detail to identify the species or to see marks or nicks on the animal’s fins or bodies. We are interested in tracking the presence, behavior, and condition of these animals. If you see unusual marine mammal species, please contact Cascadia Research. Many of these species, except for the harbor porpoise, are not commonly sighted in Puget Sound. It combines information about distinguishing features and video clips of six marine mammal species including harbor porpoise, common dolphins, bottlenose dolphins, Dall’s porpoise, Pacific white-sided dolphins, and killer whales.
We have created this short video to help people identify which species they are seeing. Sightings of common dolphins and bottlenose dolphins have increased considerably since 2016 and Pacific white-sided dolphins are seen from time to time.Ī few species of animals can look a lot like a dolphin, especially from a distance. Harbor porpoise returned to the Puget Sound around 2000, and sightings of several dolphin species have been increasing since 2010. Further out in the ocean, ambient sounds from wave action may serve the same purpose.In the late 20th century, the only small cetaceans you were likely to see in the Puget Sound were Dall’s porpoise.

These may allow cetaceans to ‘see’ fish without the need to use their own echo location – which might alert fish of their presence. Dolphins are highly social animals and can communicate with more than 1000 different vocalizations. For example, in shallow tropical and semi- tropical waters, snapping shrimp product continuous ‘clicking’ noises. 3.4K 724K views 1 year ago Please Subscribe. There are many ‘noise’ sources in the ocean that could act to ‘illuminate’ objects with sound that cetaceans detect. Singing dolphins and the sound of the ocean make your baby fall asleep. Therefore they may be able to convert sound into an acoustic image in a section of their brains which allows them to ‘see’ in the darkness of the ocean, or in the murky waters of river deltas. It is reported that cetaceans have a large portion of their brains devoted to auditory senses. The video showcases a diverse range of creatures, from the towering giraffe to the tiny duck, each. So people can easily hear them with the proper hydrophone ( underwater microphone). Video is an educational exploration of the different habitats that these animals call home. While echo location clicks can range up to about 150,000 Hz (about 8 times higher than the normal human hearing range), a lot of these clicks occur at frequencies as low as about 2,000 Hz. These dolphin sounds are well within the hearing range of people. The dolphin makes a ‘click’ which travels through the water, bounces off an object like a fish, and then hears the echo.Ĭhirps: which are tones of varying frequency – their purpose is not known.
Echolocation works like radar and is used by dolphins to find food – like schooling fish. Sort of like a sound ‘hand shake’ or greeting.Ĭlicks: which are generally used for some form of echolocation. You often hear a loud whistle from a nearby dolphin, followed by a similar sounding whistle from another dolphin. It appears that dolphins use these signature whistles like we use names. Whistles: which are unique to each individual animal – much like our own voices. Yet, we still don’t know what ‘they’ are talking about!ĭolphin sounds fall into several main categories:
People have been fascinated by dolphin sounds for millennia. Ancient Greek mariners listened to the sounds of dolphins through the hulls of their ships.
