What the heck is a Podcast?
Podcasts are audio and video files that you can download to your computer and listen to whenever you want. The name ‘podcast’ is a bit misleading – you do not need an iPod to listen to a podcast; anyone with a computer and an internet connection can download podcasts. Podcasts often sound a lot like a traditional radio broadcasts, but style and content vary depending on the subject matter. For instance; NPR offers podcasts of their popular radio programs, MIT provides podcasts of lectures for undergraduate classes. There are lighthearted podcasts dedicated exclusively to Harry Potter, as well as a plethora of amateur podcasts about, well, nothing at all.

To have episodes downloaded automatically to your computer, you need to subscribe to The Dolphin Pod feed. To do this, you will need a software program that knows how to look for and download podcasts from the internet – these are called ‘podcatchers’ or ‘aggregators’, and are usually free. The most popular podcatcher is iTunes, which you can download for free for both Mac and PC. Other popular software includes Juice, and Yahoo Podcasts. Once you have installed one of these podcatchers, you need to enter in the subscription feed for The Dolphin Pod, which is:

To manually subscribe to The Dolphin Pod with iTunes, do the following: open iTunes, click on advanced from the menu option at the top of your player and select ‘Subscribe to Podcast’, in the window that appears type or paste the following address: http://www.dolphincommunicationproject.org/thedolphinpod.xml
*NOTE: You will often see a little button like this , but if you simply click on it, meaningless XML script will appear in your browser. If you find one of these buttons for a podcast you want to subscribe to, you need to copy the link location shortcut that it is associated with (right click for PC) into your podcatcher in order to subscribe.
Does it cost anything to subscribe?
Not at all! The Dolphin Pod, like almost all podcasts, is free!

What is the Dolphin Communication Project?
The Dolphin Communication Project is a private, non-profit research foundation organized to further the following goals: 1) To promote awareness of marine mammal conservation, 2) To increase knowledge of communication behaviors between and among all dolphin species. The Dolphin Communication Project works toward advancing these goals by organizing/conducting underwater research expeditions/studies in dolphin communication, encouraging cetacean intern experiences, and fostering collaborative endeavors with scientific and educational programs.
The Dolphin Communication Project (DCP) looks at how dolphins communicate and attempts to shed more light on the meaning of their interactions. With research ongoing since 1991, our questions focus primarily on communication among dolphins. As a team, DCP research scientists study four groups of dolphins in three countries: Japan, Honduras, and The Bahamas. In Japan, we study Indo-Pacific bottlenose dolphins around Mikura Island. In Honduras, we study common bottlenose dolphins at the Roatan Institute for Marine Sciences (RIMS). In The Bahamas, we are studying dolphins at two sites: around Bimini Island, we are focusing on wild Atlantic spotted dolphins and bottlenose dolphins; and at Dolphin Encounters in Nassau, we focus on bottlenose dolphins in human care.

You haven’t answered my question….
Hmm, you had better contact us with your question…
Dolphins are mammals. This means that they breathe air, give birth to live young and nurse those young. Fish however, lay eggs and breathe underwater through their gills. Sharks are a bit different. They are fish, but some give birth to live young. However, all sharks also breathe through their gills. Sharks' skeletons are made out of cartilage, not bones.
In the Bahamas, spotted dolphins have to be on the look out for three species of sharks. The hammerhead shark, the tiger shark and the bull shark. Their best defense against these sharks is avoidance. Contrary to popular belief, dolphins do not seek out shark interactions. If they should be threatened by sharks, however, they can defend themselves with their strong rostrums and powerful flukes. Also, sharks in this area tend to travel alone, while dolphins travel in groups-anywhere from 3-30 dolphins. The more dolphins, the more eyes, ears and echolocation to keep an "eye" out for sharks! Aside from sharks, spotted dolphins in the Bahamas have to be concerned about fast boats. Boats that are driven erratically and fast than the dolphins can swim (up to 25 mph), put the dolphins at risk for painful and sometimes fatal propeller wounds. Improperly used and discarded fishing hooks and lines can also cause grave injuries to the dolphins. An important reason to remember to keep our oceans clean!
Although there have been reports of dolphins giving birth to twins, they most often give birth to one calf at a time. When two dolphins are born together, one usually doesn't survive. They can stay with mom until she gets pregnant again, between 3-5 years. Gestation period is11-13 months.
No, dolphins are very promiscuous. Males and females do not stay together; a calf will stay with its mother. Males are not involved in the care of calves.
Cetaceans is a collective term for whales, dolphins and porpoises. The name is derived from the scientific (Latin) name of these animals: Cetacea.
Dolphins are marine mammals, but there is also a fish species that's often called "dolphin" or "dolphin fish". Its scientific name is Coryphaena hippurus. To avoid confusion with the mammal species its Spanish name "dorado" or its Hawaiian name "mahi mahi" is often used. Because of the confusion between the mammal and the fish species dolphins have in the past erroneously been called porpoises, especially in some US regions, where the fish species is common. In older books you can encounter the name "bottlenose porpoise" for the bottlenose dolphin, for instance. Dolphins and porpoises are however members of different whale families. You can find more information about the dolphin fish, including its common name in other languages, in the FishBase database, online at http://www.fishbase.org/
There is not really one smallest species. The smallest species include: True dolphins (Delphinidae): * Tucuxi (Sotalia fluviatilis) - 1.3 to 1.8 m * Hector's dolphin (Cephalorhynchus hectori) - 1.2 to 1.5 m * Black dolphin (Cephalorhynchus eutropia) - 1.2 to 1.7 m * Commerson's dolphin (Cephalorhynchus commersonii) - 1.3 to 1.7 m River dolphins (Platanistidae): * Franciscana (Pontoporia blainvillei) - 1.3 to 1.7 m Porpoises (Phocoenidae): * Vaquita (Phocoena sinus) - 1.2 to 1.5 m * Finless porpoise (Neophocaena phocaenoides) - 1.2 to 1.9 m
The killer whale (Orcinus orca). Male killer whales can grow up to 9.6 m (31.5 ft). Spotted dolphins get to be about the size of a grown human-between 4-6 feet, up to 250 pounds. When they are born, they are much smaller-usually between 2-2.5 feet. Bottlenose dolphins grow to be between 6-8 feet.
The taxonomy of whales and dolphins is still subject to change. But in the most common view, the family of dolphins (Delphinidae) consists of 32 different species. Closely related families (the white whales (Monodontidae) and river dolphins (Platanistidae) have 2 resp. 5 species).
Most dolphins live in the ocean and the ocean water is too salty for them to drink. If they would drink sea water, they would actually use more water trying to get rid of the salt than they drank in the first place. Most of their water they get from their food (fish and squid). Also, when they metabolize (burn) their fat, water is released in the process. Their kidneys are also adapted to retaining as much water as possible. Although they live in water, they have live as desert animals, since they have no direct source of drinkable water.
