Yep. Dolphin attacks on humans are about as common as shark attacks. The difference is that dolphin attacks are very rarely serious enough to require hospitalisation and never fatal. As a result people know that sharks are prone to attacking humans but largely ignorant of dolphin attacks on people.\n\nIt's amazing how many people believe that dolphins won;t attack people.\n\n\nIn the past few months there have been reports of dolphins “attacking” humans that have come to interact with them. The latest are those of a 12 year old girl, a 34 year old woman, a 26 year old mother of two, and a 10 year old boy. All of these victims were not seriously injured, but were very frightened by their experience.\n\nDolphins, as well as other mammals, have a natural instinct regarding eating, mating, and social interaction. By humans coming into the world of dolphins they may interrupt the dolphins routine. This may be distressing to the dolphins, which may show this by attempting to get the human to flee, as they would with anything else they see as a threat.\n\n Further damaging a reputation tarnished by reports of violence, a bottlenose dolphin off the coast of Florida bit a 14-year-old French tourist who tried to pet it this week. The girl, who was swimming in the Intracoastal Waterway near Nokomis, Fla., suffered only minor cuts and bruises. She was taken to a local hospital, treated and released.\n\nWhile this attack certainly wasn’t fierce, local whale and dolphin experts say it may serve to accelerate a changing view of dolphins in the wild. The incident comes just months after an extensive report published in The New York Times cited similar occasions on which the seemingly friendly creatures display violence toward humans. In this case, 14-year-old Pricilla Jones was the unassuming victim. Witnesses say that Jones, a tourist from Paris, swam out to greet the dolphin and tried to pet it on the back. In response, the dolphin thrashed around in the water around her, biting her on the hand.

Observations of bottlenose dolphins in aquariums and zoos, and of whales and dolphins in the wild, show two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal. Individual dolphins also enter a deeper form of sleep, mostly at night. It is called logging because in this state, a dolphin resembles a log floating at the water's surface.\nWhen marine mammals sleep and swim at once, they are in a state similar to napping\n\nAdult male dolphins, which generally travel in pairs, often swim slowly side by side as they sleep. Females and young travel in larger pods. They may rest in the same general area, or companionable animals may pair for sleeping while swimming.\n\nWhile sleeping, the bottlenose dolphin shuts down only half of its brain, along with the opposite eye. The other half of the brain stays awake at a low level of alertness. This attentive side is used to watch for predators, obstacles and other animals. It also signals when to rise to the surface for a fresh breath of air. After approximately two hours, the animal will reverse this process, resting the active side of the brain and awaking the rested half. This pattern is often called cat-napping.

Chlorine in the water is probably bad for us in the long run, but if it wasn't there we'd be dead already from cholera or typhus.  There is no such thing as "safe", you just need to gauge the amount of risk you are willing to tolerate for an enjoyable life for you and your family.

I was thinking this question only yesterday! How strange! I'd like to know the answer to this one too. I thought Tuna were smaller than Dolphins, so they can't escape through holes in the net.

I don't know about all the changes over the last 30 years, but I do know a few more recent ones.  With back they are allowing flip turns now.  With breast, they allow one dolphin kick during your pull out, you're head can now be completely submerged during the stroke, and when you do your turn you are now allowed to have your hands on different plains as long as they touch at the same time.

Dolphins live in a tribe.There can be up to 150 dolphins in each tribe.The mother is the centre of the family.\n\nWhen hunting they use a method called "Kettle technique".\nThey manage to gather the fish together into a ball shape by letting out piercing cries and by surrounding them with bubbles. In this way it is very easy to catch them.\n\norcas work in co-operation with one another, swimming in unison to create a wave pattern in an attempt to knock the seals off of the ice. This clever hunting technique quickly and efficiently could provide dinner for a pod of orcas.\n\nI once read about a incident where the orcas followed a young blue whale and its mother for 4 days and when it got exhausted they had eaten it.The mother was too big for them and they could possibly not harm it.

Let me see if I can explain this from the point of view of an Instructor. First, I cannot simply TELL you how to do something and expect you to do it correctly. I would need to see you do it and SHOW you what you are doing wrong. You would need to SEE it and understand how to do it correctly. \n   Second, if I do tell you how to do something, and you get hurt doing it wrong, or doing it right but without training, who's fault is it? Mine.\n   Hurting someone is very easy. Healing them is very hard. Knowledge without proper training is very dangerous. \n   So, do not take this wrong, because your enthusiasm is refreshing, please get proper instruction before you try these things. Your question is like asking a swimming instructor to tell you how to float...it sounds like fun until you get into the deep end and start hearing "glub, glub, glub..."

I have been diving for 30 yrs. and used all kinds of things. True, you can use spit but it really doesn't seem to be as effective as defog that is sold in dive shops and some sporting goods stores. Baby shampoo works well too. My favorite is liquid dish soap! I know, it doesn't sound like a good idea but hear me out.\n\nWet your goggles and place one drop for goggles. Masks may need more. Spread the liquid evenly. RINSE WELL (I give my mask a few shakes in the water) to avoid stinging later on. Do not use your fingers to rinse because you will remove the film. Your fingers have oils that will cause your goggles to fog too.\n\nThe reason I like dish soap because it is cheap and readily available. Most are biodegradable.\n\nWhy it works...after washing, dish soap leaves a 'sheeting film' that prevents dishes from leaving water spots on dishes. It is gone after it evaporates. When you wear a mask or in this case goggles it traps moisture inside so it doesn't evaporate.\n\nYou may have to reapply if you remove your goggles for too long or often. Remember to rinse it well. I have used this for hundreds of diving customers with no allergic reaction but if you do get irritation, discontinue.\n\nHope this helps!

I recently saw a programme on National Geographic Channel where they showed many animals masturbating.  Can you believe that dolphins are pervs?LOL.I guess even animals need a little fun!

Dolphins are being protected now, and are growing in numbers again, and they seem pretty happy when I use to see them! But im not a dolphin, yes yes...believe it or not...I'm not. =)

As a former lifeguard, I agree with Mike_1am. With the side stroke, you carry the person with one hand and use the other to swim. With the back stroke, unlike the swimmers in competitions I was taught to carry the person with both hands and use only my feet to propel my way back to safety.

Take a look at the pyrotechnics chapter of this side.\n\nhttp://www.vk2zay.net/\n\nCareful: it is neither simple nor without danger.

Sonar has a few advantages.\n\nDolphin eyes and brains are set up in a way that each eye, and each part of the brain sees only in one direction. In other words, a dolphin can see to its left and its right at the same time, with different parts of the brain, but never can it see one image with both its eyes. This means that it can't see ahead very well, and that (and this is just a guess) it cannot see 3 dimensions, only 2. It's a lot like its whole world is like looking at pictures or tv. \nSonar gives the dolphin a good, 3-dimensional picture of what lies ahead in a pretty big cone.\n\nalso, sonar is not as easy to trick as vision. good camouflage can make an octopus or a fish invisible to the eye, but sonar can find them.\n\nsonar can see what is hidden. many dolphins hunt by detecting, with sonar, fish that are under the sand, and then using a concentrated beam to move the sand and get the fish out.\n\nand a no less important one is detail. dolphin sonar can be incredibly detailed. some dolphins can identify a specific shark species at, i believe, a distance of half a mile, and more importantly, tell whether the shark's stomach is full or empty. I can definitely see survival value in that!\n\nfinally, it's versatile. it's a sensory organ, a weapon, a pointing device (dolphins can point things out to each other by directing their echolocation beams), and even a healing device (dolphin sonar is thought to help healing through cavitation - hence dolphin assisted therapy).

Suppose if some dolphins/porposises were taught to jump out of nets at the right time and were released, they could teach others?\nThe japanese deliberately use nets they can't get out of because they see them as preditors of the fish.

I think the best adventures I have are when I'm surfing.  I'll paddle to the outside and wait for a set to roll through, sometimes while I'm waiting, a pod of dolphins will swim by or start feeding right in front of me.  One time a sea lion swam under my board - that was cool, but a little freaky.  It's nice being out in nature and getting to see up close some of the wildlife people take for granted.  \n\nAn adventure of a friend that I thought was scary:\nOne day my friend was out surfing with one of her friends and catching some really good waves.  She was waiting on the outside with her friend when she notices a large shadow under her board - she looked at her friend and asked, "What are the chances that's a sea lion?".  Turns out it wasn't, but a huge shark!  I almost pissed myself when she told me this story.  SCARY!

Mainly their thick outer layer of blubber is able to absorb a lot of the pressure.  Their immense size does help even it out.  Unfortunately, even though they are built to be able to dive that deeply, it's not a harmless thing.  Whales do get the bends.  Often whale bones, especially those of sperm whales, show signs of nitrogen bubbles in the blood and tissues.  Over time it does cause them pain and in some rare cases some deformity.  So they're designed to be able to do it, but it is not risk-free to the whale.  There is a biological cost.
