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 do you know that the dolphin is the smartest animal?
well its like this dolphis is the smatest because in a non-fiction book i found out that dolphins is smartest because when your lying about in the water (like wow)they go out and save you & they look very preety
Can Crocadiles breath under water?
No, but crocodiles can hold their breath under water for long periods of time if needs be (some large adult crocs have been known to hold their breath for 2 hours or more!)
People use dolphins for food I think its stupid and cruel you should see the videos on u tube their horrible
(((sigh....I guess the fact that dolphins are cute makes eating them cruel even though they're carnivores and eat countless fishies :/ ... but they're used for entertainment mostly, and have been used therapeutically in China to help autistic children. They're also used for EOD (explosive ordnance disposal) by the US Navy. But yes, people eat them. Get over it hippie that's just the way the nature you love so much happens to be.)))
How long are a dolphin's life span?
•The maximum age for bottlenose dolphins is between 40 and 50 years. The average 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.
The male dorsal fin averages 6' tall.
The orca is the fastest marine mammal able to swim 35 mph.
A Killer whale weighs up to 1000 stone which is 14000 pounds, they are members of the dolphin family and their average length is 26-32ft
Males typically range from 6-8m (19-26 ft). They can weigh up to 6 tonnes.
Females are smaller, generally ranging from 5-7m (16-23 ft) and they may weigh from 4 to 5 tonnes.
The largest Killer Whale ever recorded was a male off the coast of Japan, measuring 9.8 m (32 ft) and weighed over 8 tonnes(17,636 lb).
Calves at birth weigh about 180 kg (350-500 lb) and are about 2.4 m long (6-8 ft).
The Killer whale's large size and strength make them among the fastest marine mammals, often reaching speeds in excess of 56 km/h (35 mph). The males dorsal fin is about double the size of the females.

Ive done a big big big big big!!!!!!!!!!!!!!!!! project on Orcas (also know as killer whales) so i should know and i do know here you go MALE(bull):5,8 to 6,7 meters long can way up to about 500kg Female(cow): 4,9 in length and can weigh up to about 3500kg.What does plankton get eaten by?
Many creatures dine on zooplankton. Baleen whales and blue whales are the largest creatures to eat zooplankton. Tiny fish and snails also eat zooplankton.
Fish move by swimming. They move their fins back and forth to swim. Some fishes have a swim bladder which is an organ that help bony fish stay in different depth.
Can dolphins survive in salt water?
Dolphins do not necessarily need salt water. Most species of dolphins live in salt water (although they do not drink the water because it is far too salty). Freshwater dolphins, also called river dolphins, usually live in fresh water, with the exception of the La Plata dolphin. As noted, dolphins do not drink salt water because synthesizing the salt water would cause water loss as opposed to water gain (and also why humans should not drink sea water either). Rather, dolphins get their water through the metabolism of their food, much like Australian Desert mice.
Dolphins talk to each other by using clicks and whistles. Some people use click languages. Some people use whistle languages. No group of people speak a language consisting of both clicks and whistles and no spoken words. Perhaps if someone created one it would become possible to talk to dolphins.
What is the body of a dolphin covered with?
A dolphin is covered with a very thick skin, over 10 times the thickness of land animals. This skin is constantly flaking off and being replaced by new skin, in fact it is being replaced as quickly as every two hours. This helps keep the dolphin swimming quickly.
Yes. Their camouflage is they blend in to the ocean, what I mean is if you are under a dolphin and look up, it will be hard to spot because of its white under belly. If you look at it from the top you will see its blue top side and it will blend into the ocean.
How do dolphins go to the bathroom?
I think dolphins let out their waste in the water. They have no other place to go unless they use it on land but other than that i would think that they either use it in the water, or on land.
How many babies can a bottlenose dolphin at a time?
Normally only one at a time. Dolphins virtually never have twins, they nurse their calves anywhere from 3 to 10 years. Since a female dolphin can live to be late 40's, she may have many young throughout her lifetime.
dolphins are not asexeual, meaning they reproduce without the aid of a mate, they do infact need a mate to reproduce and are the only other mammals on earth that, like humans, have sex for fun.
Do dolphins eat plants or meat?
Dolphins are meat eaters, because they eat fish and squid. They can eat up to 40 pounds a day. They need this much food to keep up their energy, because they can swim up to 70 miles a day. Just a fact: When they sleep, they shut off half of their brain so they can be alert of any enemy's. The brain that is not shut off, also needs to make sure the dolphin doesn't drown in the water. This is because dolphins are conscience breathers, meaning they have to remember to breath, unlike us.
How long can a crawdad stay under water?
I believe they can live up to a few months if the area is humid. Their gills just need to remain wet, but can pull oxygen from air.
they are diurnal because they are never spotted during the night. they always apear at the surface during the day not the night. eventhoug people say that they are nocturnal i think that they are diurnal. if you think that you are a smart person please think. when have you ever seen a picture of a killer whale are any whale at night? think and dont be and idiot
WELLLL.. i beg to differ..
I know for a fact that blue whales do not sleep. This is because if they did, then they would drown. Think about it, how to whales breath? through their blowholes. How do they breath if they are sleeping? They don't. That's why most whales, it not all, are neither nocturnal or diurnal, because they dont sleep. Also, whales dont have involuntary breathing, they have to think about breathing and they have to make sure that they actually breath every 30 minutes or so. They do, however, take little napes now and then, but other than that, they get their energy from their food. Now it's time for you to think and stop being an idiot because CLEARLY most of the whales would be dead if they slept. If you dont believe me, then look up 'do whales sleep', and you'll find that they either dont sleep, or half of their brain sleeps at a time, like dolphins.
dolphins swims so fast not because of their skin structure but because of large force exerted by their tail . dolphin can exert a force of 400lb by their tail as compared to olympic swimmers (produce only 60-70lb of force).
Do all dolphins have pointy noses?
The nose is on the top the dolphins head. This is why a spray of mist comes up when it breathes. And not all dolphins have pointy beaks. The beak is where the mouth is. Porpoises have blunt heads. They have no beak at all.
