This holiday is well known around the world as well as in the grand plan of products, Dolphin Day is possibly probably the most well-known unofficial holidays around the globe. Getting acquired steam within the the nineteen nineties and ongoing into todays, this holiday concentrates on the world plight from the whales. Thinking about how similar whales seem to be to ourselves, we might even call Dolphin Day one of the most “human” holidays which are celebrated.Occurring every year in September, Dolphin Day doesn't have one “official” location. On the other hand, events and awareness conferences occur in main metropolitan areas around the world. A number of biggest venues include Bay Area, New You are able to City and Tokyo, japan. Typically, Dolphin Day places a specific focus on limiting Japanese dolphin tracks, because these have obtained much publicity throughout the final decade. Every year, this worldwide event is constantly on the gain an increasing number of supporters. Hopefully, the long run will discover a complete prohibit of dolphin hunting even though this holiday may no more be needed, it'll indeed be considered a happy ending for the whales as well as their human advocates!

How do dolphins sleep?

Dolphins have to be conscious to breath.[1] This means that they cannot go into a full deep sleep, because then they would suffocate. Dolphins have "solved" that by letting one half of their brain sleep at a time. This has been determined by doing EEG studies on dolphins. Dolphins sleep about 8 hours day in this fashion.

A dolphin's behavior when sleeping/resting depends on the circumstances and possibly on individual preferences. They can either:

1. swim slowly and surface every now and then for a breath

2. rest at the surface with their blowhole exposed

3. rest on the bottom (in shallow water) and rise to the surface every now and then to breath. [2]

How smart are dolphins?

The short answer to this is that we do not know. There is no reliable method to measure intelligence in humans across cultures, so it is not surprising that comparing humans, dolphins, apes, dogs, etc. is impossible. There are some indications of their potential: they are fast learners and can generalize (which is also true of pigs). Also they can learn to understand complicated language-like commands (which is also true of the great apes).

How much do dolphins eat?

Bottlenose dolphins eat several kinds of fish (including mullet, mackerel, herring, cod) and squid. The compostion of the diet depends very much on what is available in the area they live in and also on the season. The amount of fish they eat depends on the fish species they are feeding on: mackerel and herring have a very high fat content and consequently have a high caloric value, whereas squid has a very low caloric value, so to get the same energy intake (calories) they will need to eat much more if they feed on squid than if they feed on mackerel or herring. On average an adult dolphin will eat 4-9% of its body weight in fish, so a 250 kg (550 lb) dolphin will eat 10-22.5 kg (22-50 lb) fish per day.

How long do dolphins live?

The maximum age for bottlenose dolphins is between 40 and 50 years. The average age a dolphin can get (the life expectancy) can be calculated from the ASR Annual Survival Rate (the percentage of animals alive at a certain point, that is still alive one year later). For the dolphin population in Sarasota Bay, the ASR has been measured to be about 0.961. This yields a life expectancy of about 25 years. For the population in the Indian/Banana River area, the ASR is between 0.908 and 0.931. This yields a life expectance between 10.3 and 14 years. So the actual life expectancy differs per region. [3]

How deep can a dolphin dive?

The deepest dive ever recorded for a bottlenose dolphin was a 300 meters (990 feet). This was accomplished by Tuffy, a dolphin trained by the US Navy. Most likely dolphins do not dive very deep, though. Many bottlenose dolphins live in fairly shallow water. In the Sarasota Bay area, the dolphins spend a considarable time in waters that are less than 2 meters (7 feet) deep.

Other whale and dolphin species are able to dive to much greater depths even. The pilot whale (Globicephala melaena) can dive to at least 600 meters (2000 feet) and a sperm whale (Physeter macrocephalus) has been found entangled in a cable at more that 900 meters (500 fathoms) depth.

Recent studies on the behavior of belugas (Delphinapterus leucas) has revealed that they regularly dive to depths of 800 meters. The deepest dive recorded of a beluga was to 1250 meters. [1]

Do dolphins drink salt water?

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 comes 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 live as desert animals with no direct source of drinkable water.

Mass strandings: Why?

If a single whale or dolphin strands, it usually is a very sick (and exhausted) animal. Such an animal often has some infections (pneumonia is almost always one of them) and a lot of parasites (worms in the nasal passages are very common). Sometimes these animals can be rehabilitated, but often they are so sick they won't make it.

Some species of whales and dolphins occassionally strand in groups. A stranding of 2 or more animals is usually called a mass stranding. There are a number of theories that try to explain the occurrence of mass strandings. No theory can adequately explain all of them. In some cases it will be a combination of causes. The most common explanations are:

deep water animals (the species that most often are the victim of mass strandings) can not "see" a sloping sandy beach properly with its sonar. They detect the beach only when they are almost stranded already and they will panic and run aground. [1]

Dolphins!?!!??!!?

A lot of people want that job and there aren't enough slots for everyone. You would need to start volunteering at your local zoo and stuff like that. Anything with animals, not just dolphins and whales, will help you. Some zoos have a trainer-for-a-day program, I have done one myself and it was a lot of fun. There is a neat sounding program in the Florida Keys, where you learn about training dolphins. It lasts a week and it sounds like it would a good thing to do if you are that interested. There's the website, you should check it out, if you are serious.

Hope I helped.

Jobs involving being around dolphins...?

Working with dolphins is not about 'playing in the water' with them. Even in the few jobs where you get into the water with them, there is little 'play' involved.

Few jobs allow interactions, apart from the ones in a captive setting and if you love dolphins, you wouldnt' want to be part of that industry as it has a lot of negative effects on them: they get sick more easily and suffer from a variety of respiratory and stress related diseases, they have to perform for food and they often live only about half as long as in the wild. In the wild they may travel hundreds of miles in a day, yet in a tank they are confined to continuously swimming in circles and often made to interact with people during 'swim with the dolphin' programs or training.

As a dolphin trainer, yes, you will get to interact with the dolphins, sometimes you will be in the water with them but you will not be 'playing' with them, you will be controlling them. As a trainer, you cannot afford to be their friend, you need to be at every point of the interaction, the person in charge. There is little space for play. What looks like play in these shows, is the dolphin trainer telling the dolphins how to behave every step of the way.

Another job you would be in the water with them would be working in rehabilitation, but there would be less play there as you would be dealing with ill animals that need medical attention and involves a lot of supporting and walking animals around in circles to keeping them breathing and getting very cold and wet. This in my opinion would be a whole lot more worthwhile than dolphin training as you would be actually aiding the animal.

The only other thing I can think of is something like dive or snorkel operator, taking people to dive/snorkel to see dolphins however actually getting into the water with wild dolphins is restricted (for very good reasons) in a number of countries, so you would have to check if it was legal where you live, I know for sure it is not in the US (at least Florida) and the UK. Also, there would not be much play and touching either as responsible tour operators maintain a complete 'hands off' approach.

Scientists or wildlife film makers may occasionally get into the water to film dolphins and dolphin behaviour but the key to these dives are maintaining a complete neutral position and pretty much ignoring the dolphin should it approach to make yourself as uninteresting as possible in order to capture natural behaviour.

A lot of people love dolphins and want to get close to them, touch them, play with them. They are pretty amazing so it's understandable, however, consider this; how would you feel if a bunch of people came into your room while you were trying to do an important piece of homework that would determine your mark for an important course and started crowding around you wanting to touch your hair or asking you to play, sure it may be mildly entertaining at first but I bet you would get pretty annoyed with it after a bit!

It's the same with dolphins, you may want to play with dolphins, but the dolphins do not neccessarily want to play with you! They have a lot of things vital to their survival to do in the wild and playing with people is not one of them. Some populations of dolphins have even been driving out of their home ranges by over enthusiastic people trying to swim with them all the time!

Well and in captivity, captivity is just a terrible existence for such a magnificent predator and it has severe effects on them, many dolphins get aggressive and as many as 50% of people working with marine mammals have reported that they have been injured or attacked by the animals they are working with. They are not cute and cuddly as they are made out to be, their are admirable apex predators, but as such they have what some people may refer to as a nasty side too. They harass other dolphin species, sometimes people, some populations kill harbour porpoise for sport, males commonly commit infanticide (killing baby dolphins)....There are instances were people have been killed by them or at least severley injured, they are a force to be reckoned with.

The best way to appreciate dolphins is to do just what you don't want to do, watch and observe, it's the best for the animal and yourself.
