Dolphins and Porpoises
Considered not a fish, dolphins and porpoises belong to the group of toothed whales that have skin, not scales. The significant difference between them is that dolphins have a beak, a melon-shaped head and a dorsal, while porpoises have none.

How many dolphins are there usually in 1 pod?
There are a bunch of them. Sorry, but they all have different amounts.
What are some thoughts and opinions about dolphins?
Advantages:
There are many pros for whaling, mainly that whaling, if controlled, can be sustainable, and in fact, have less ecological impact than Western-style farming.
Many people don't think that we will quite happily eat beef, bacon, venison but compare that to the size of a whale. A whale will people for the same amount of 100's of cows being cut up for beef. I bet people are a hundred birds being chopped up to mice, so why don't mice hunt us? That's why Japan is so obsessed with killing them. It's obvious, Japan is after the big money.
Disadvantages:
The cons are that there is only a small population of whales, and numbers are declinging from 3,000 worldwide, but in fact, the main species that are being whales right now, the Minke, is actually growing in population. It is okay to me, if Japan limits how many Minke whaled they kill. AND NOT BABIES! Seriously, just kill adults and no bluewhales, one of many endangered or threatened specimens.
"The IWC (International Whaling Commission) The IWC is the organisation responsible for regulating whaling. It was formed in 1946 to manage sustainable hunting of whales. Now it is responsible for conservation of whales, but it is still an imperfect system reflecting its pro-whaling origins.In 1982 the IWC voted to introduce a Moratorium on Commercial Whaling, to take effect in 1986, however Japan never stopped killing whales (see 'Scientific whaling' below).In fact, more than 25,000 whales have been killed since the Moratorium was supposed to come into force.IWC decisions are based on a vote, and Japan "encourages" small third world countries to join the IWC and vote on their side. Japan is alleged to have handed out more than $400 million in bribes so far.
Japanese 'Scientific Whaling' Japan exploits a loophole in IWC legislation, and has never stopped killing whales despite the Moratorium. They simply assign themselves a permit to undertake 'scientific whaling' (ie. killing whales for the purpose of scientific research) and continue hunting whales as before.This practice has been described as "commercial whaling in disguise" - particularly as the meat ends up for sale in high class Japanese restaurants.Japanese claim to be undertaking research by killing whales. However, most of the data collected by the Japanese 'Scientific whaling' programme is not required for management or conservation of whale stocks and is never published in reputable scientific journals.Many Japanese 'research' objectives are based on unsubstantiated or incorrect scientific assumptions. The few relevant research objectives they have (relating to population makeup etc) can be much better addressed using non-lethal methods (e.g. tagging, DNA profiling, and photo-ID etc), or by analysing a century's worth of commercial catch statistics, plus data from the previous 20 years of Japan's lethal research programme.Most Japanese 'research' objectives are directed towards finding data to support a return to commercial whaling, and/or studies on how to make whaling more efficient.
Whales and whaling Blue whales are the largest, and also the rarest whales. There were once 220,000 Blues in Southern Ocean, reduced to around 500 now (maybe 3000 worldwide) by past overhunting. This represents a reduction to approximately 0.2% of their original Antarctic population (or 1.5% worldwide). Despite being protected since the 1960s, their numbers have not recovered.Minke whales are the commonest of the rorquals ('Great whales') - mainly because they are the smallest so have not been subjected to the same hunting pressure yet (they were not targeted by whalers until the 1970s when larger species became too rare). Recent estimates show there could already be as few as 250,000 Minkes from 3 different sub-species in the Southern Ocean, despite Japanese claims of close to 1 million.The whales Japan hunts are the same ones that migrate past the coasts of NZ and Australia, and breed in the Pacific Islands. In addition to the 'scientific' whaling loophole Japanese whalers defy the Southern Ocean whale sanctuary declared in 1994 by killing them right in the heart of the protected area.A lot of the legitimate science is disputed by Japan which comes up with its own (dubious) figures to justify the supposed sustainability of a continued kill. They also argue it is a cherished cultural tradition for Japanese people to keep killing whales - However a recent Japanese Newspaper poll found only 4% of Japanese regularly eat whale meat.Massive industrial-scale Antarctic whaling 10,000 km from Japan is definitely not a tradition and only began around World War II when whale stocks around Japan were already commercially extinct (unviable for continued hunting). Whales were initially targeted by the Japanese for oil as a source of foreign currency!
Recent Developments Japan initially claimed they were taking only Minke whales, but covert genetic analysis by New Zealand scientists revealed some meat for sale in Japan in the 1990s came from dolphins, and some from endangered species such as Sei, Fin, and Humpback whales.The NZ Conservation Minister said anti-whaling nations struggled to comprehend Japan's rationale for continuing whaling. "There is no financial value in it, there is certainly no science in it, so it has to be a twisted nationalism."Japan continues to demand an end to sanctuaries, and an abolition of the Moratorium to allow a return to commercial hunting. Following Japan's example, Norway and Iceland have also resumed whaling in the Northern Hemisphere in recent years, killing hundreds of Minke whales, along with Fin and Sei whales (both species listed as 'Endangered' i.e. facing a very high risk of extinction in the wild in the near future).At the 2006 IWC meeting Japan managed to (buy enough support to) win the vote declaring that the Moratorium on Commercial Whaling is unnecessary and blaming whales for depleting the world's fish stocks.Following this success, Japan announced its plans to expand its whaling effort to kill the following numbers whales per year, beginning in the 2006-07 season:
In the Antarctic: Double their current Minke whale kill to 93550 Humpback whales [the total population estimated to pass through New Zealand waters is only 2000!] (species listed as 'Vulnerable' i.e. facing a high risk of extinction in the wild in the medium-term future)up to 50 Fin whales (species listed as 'Endangered' i.e. facing a very high risk of extinction in the wild in the near future)
In the North Pacific: 220 Minke whales50 Bryde's whales (species listed as 'Unknown Status' due to lack of data)50 Sei whales (species listed as 'Endangered' ie. facing a very high risk of extinction in the wild in the near future)10 sperm whales (species listed as 'Vulnerable' ie. facing a high risk of extinction in the wild in the medium-term future)
What is the kingdom phylum class order family genus and species for the dolphin?
All whales belong to the same phylum, class and order (listed below). What family, genus and species a whale belongs to depends on the whale.
Phylum: Chordata
Class: Mammalia
Order: Cetacea
How many dolphin are left in the world?
170,243,000 dolphins live on this world
yes there is but when they have babys what is going to happen?... more dolphins see so there going to be more then that, at the same time there is an immense slaughter of dolphins going on worldwide, in places such as Taji(sorry for spelling) for more info on that check out the cove. :-)
The dolphin's blowhole is used for breathing. Like us dolphin's are warm blooded animals. So dolphins also need air. So when the dolphin goes out of the water it squirts out water!
What country does dolphins live?
Mostly from the pacific ocean but can come from 3 other oceans.
Dolphins are found worldwide
there is no specific part dolphins originated from
Dolphins can also be said to have 'come from' or evolved from a carnivorous mammal that lived on land, and eventually evolved to live in the sea.
Their souls originate form the Sirious stars. They are here as protectors of waters (oceans, rivers...). They came here because (many people don't know this) they hold knowledge about human race, it's past (Atlantis) and maybe it's future too. They are super intelligent creatures, 2nd most intelligent, right after mice. Also they are supposed to vome here becuase their home, star sirious b reckoned.
On Atlantis, dolphins were very respected, just like other animals, but they not only were there to protect waters, they spoke to those who listened, to deliver their knowledge onto the human race. In those days, people were on such high vibrations, that they could telepathicly communicate with each other as well as the animals. Still, dolphins do have the knowledge, the problem is, we forgot how to properly communicate with them.
What exercise does a dolphin need?
They need polluted water, water, gills ( if born with), and flesh>
How do dolphins jump out of the water?
With the design of their flukes, also known as their tail fins, and dorsal fins a dolphin is able to jump out of the water. These fins are controlled by powerful muscles that allow the animals to leap out of the water and take in air that is needed for their survival.
A baby dolphin is called a calf. However, a young dolphin that is 4-6 years old is past the calf stage of life. They are called juveniles.
When was the first dolphin born?
Portraits of dolphins can be found in the artwork of ancient Babylon. Babylonian art dates back to 2300 B.C. It is likely that man has seen dolphins as long as he has had contact with the sea.
Is a bottlenose dolphin an invertebrate?
Herbivores eat plants, and dolphins eat fish (meat) so they are carnivores.
Bottlenose dolphins eat mainly small fish and occasionally squid, crabs, and shrimp, among other small animals.
How do dolphins depend on great white sharks?
Dolphins may depend on sharks in an indirect way, in that seals and dolphins are competing for the same food source to survive, and sharks eat seals, therefore making it easier for dolphins to eat and thus, survive.
What is the biggest dolphin in the world?
Technically the 'Killer Whale', otherwise known as the Orca is the largest species of dolphin.
Why are dolphins different to fish?
fish kingdom are cold-blooded, they use gills to breathe and they lay eggs (external coldblooded whales and dolphin are warmblooded, they use lungs to breathe and they give birth( internal fertilition). they also feeds their Young consider mammals like humans.
Do people still hunt dolphins?
The Japanese are still whaling, so even though the Blue Whale is a proctected animal, it still might be hunted by Japanese whalers. Maybe not intentionally, but they certainly won't throw it back, and even if they did they whale would probably bleed to death. That's the sad facts. :(
Dolphins are mammals, meaning they nurse their young with milk. So, young dolphins will often stay very close to their mothers while they are fed by their milk. In fact, dolphin calves often stay with their mothers for up to 6 years as they learn necessary survival skills. The maternal instinct in female dolphins can be very prominent, as another dolphin will often help a mother deliver and take care of her baby dolphin for the first few years. On the other hand, fathers are known to eat their own babies in some dolphin species, such as bottlenose dolphins.
Can dolphins breathe underwater?
No, a whale is a mammal and therefor needs oxygen. Whales breath air at the surface of the water by taking quick breaths through their blowhole. A flap of skin controlled by muscles opens the blowhold when the whale breathes and closes when the whale goes underwater. Whales can hold their breath from 7-30 minutes.
Is Dolphin Tale a non-fiction book?
Gurl you best be trippin' because Dolphin Tale is definately based on a true story.
Because it is. There's not really a "why".
If you mean "what are the characteristics of a dolphin that show that it's a mammal and not a fish or amphibian", it's warm-blooded, produces milk, and gives birth to live young.
