PH1. DOLPHINS CAN BE FOUND ALL OVER THE WORLD AND IN DIFFERENT ENVIRONMENTS
There are 36 species of marine dolphins - living in nearly all aquatic environments, including oceans, coastal, estuarine and freshwater - and in temperatures ranging from less than 0°C to more than 30°C. In Britain, bottlenose dolphins are concentrated around west Wales and eastern Scotland - with the coasts of Devon and Cornwall also having pods. Scotland is home to the most northerly pod of bottlenose dolphins in the world.2. FRESHWATER DOLPHINS
The Amazon river is home to four species of river dolphin that are found nowhere else on Earth.3. UNDERWATER NOISE POLLUTION IS A REAL THREAT TO DOLPHINS
Marine traffic around the British Isles is amongst the most intense of anywhere in the world. Noise pollution from naval activity, the oil and gas industry, seismic surveys and underwater construction can stress and injure cetaceans. It also severely interferes with their ability to communicate, reproduce, navigate and find prey - sometimes proving fatal.4. THEY’RE FAST SPRINTERS
Bottlenose dolphins are usually fairly slow swimmers, travelling at about 2 mph. However they can reach speeds of over 30 mph for brief periods!5. HOW DO YOU EAT A FISH?
Probably not the same as a bottlenose dolphin, that’s for sure! They swallow a fish head first so the fish's spines don't catch in their throat.(s)orgUK
