1) How long do dolphins in captivity live?
Dolphins in captivity can live up to 60 years old, while a study research in the Indian River Lagoon found that in the wild they were living for 10 years. The causes for the early losses in nature are due to environmental stressors, diseases, water pollutance, absence of health care and food availability.
2) Do the dolphins get enough food?
Dolphins at IDC have high quality food available, according to each animal needs. The food is inspected, and carefully prepared, being delivered 3 to 10 times a day, depending on dietary needs, enrichment activities, play time and schedule. The food is also supplemented by vitamins, minerals and hydration. Everything is prescripted by a veterinary specialist, and all the dolphins are weighed frequently to guarantee that they are healthy.
3) How are the dolphins trained?

All animals are exposed to stressors in their life. However, we try to manage that they don't have to deal with more stress that they are able to cope. In the wild, they can be exposed to extreme levels of stress.
5) How many fishes do they eat per day?
A nursing calf eats 1-3 pounds/day, an adult eats 17-35 pounds/day and a lactating female eats 44-55 pounds/day.
6) Are dolphins fishes?
Although some people think that dolphins are fishes, because they live in the water, they are mammals. They have the same characteristics that we have, they nurse, they deliver live birth, they have warm blood and they have hair.
7) Do dolphins sleep?
They do sleep, but there is no clear rest periods because they are subject to predators. For the same reason, one brain hemisphere sleep at a time, so they can watch who is approaching. The sleep behavior is also affected by environmental conditions and it changes seasonally.
8) How to tell them apart?
Each dolphin has individual characteristics, such as vocal patterns, behavioral patterns, body marks and body shape.
9) Were all the dolphins born at
Killer Whales that live in SeaWorld are unhealthy to the ones compared in the wild. In the documentary Blackfish they went to SeaWorld to ask about the lifespan of a whale. They workers at SeaWorld responded saying they live from 20-30 years and that in SeaWorld they live more (Cowperthwaite). Killer whales life span is like a humans were males will live from 60 to 70 years and females live from 80 to 100. Killer whales that are kept in captivity are cutting their
Dolphins live in packs also known as pods. All dolphins don't live in the same pod forever they might move from pod to pod. That's why there are smart because they ned brain capacity to move from pod to pod and not break chemistry. Most pods don't care for the leader beside the bottlenose dolphins. regardless most species pods do not have any membership. a lot of pods are separated from male to female. Male pods can live with the same members ranging from 10 to 25 years. Male pods cooperate during mating season so each dolphin gets a specific female. Most male pods compete and team up to defend themselves. There are three different types of pods, nursery, juveniles, and males. Nursey pods are full of females and their calfs. Juvenile pods
Orcas in captivity will live at only half their lifespan then which they would've lived in the wild. They only live to be about 30-50 years old in Seaworld's care. However in the wild males live to be at least 60-70 and among females about
David and Melba Caldwell were the first investigators postulating that signature whistles may represent a unique vocalization, different for each dolphin. These stereotyped whistles seem to be stable for a long time (Sayigh et al. 1990, 2007; Bruck, 2013; Luís et al., 2015), suggesting that these signals may be involved in individual identification (Caldwell & Caldwell, 1965; Tyack 1986; Caldwell et al., 1990; Sayigh et al., 1990; dos Santos et al., 2005).
Have you ever saw something move around you in the ocean ,or saw someone run out the ocean because there something in there? Sharks and dolphins can be similar or different by their trait, diet, and habitat.
One such area where dolphins were needed was Operation Iraqi Freedom. In order to speed up the process to detect underwater mines during Operation Iraqi Freedom, dolphins were deployed in the Middle East to locate them, this allowed ships entering the harbor to travel much safer than if the dolphins would not have done that (Barfoush). To train dolphins for operations like this the Navy has a practice minefield set up in San Diego where their dolphins quickly learn how to locate their mines in only a few trials; every few days the mines are moved around so the dolphins can have a fresh challenge (Barfoush). For a dolphin to be ready to search for underwater mines, they undergo a three year training course where they will be taught very strict
The eating habits of the dolphin can vary by habitat, location and the food accessibility and availability. Bottlenose dolphins may eat many various aquatic organisms. Usually bottlenose dolphins eat fish and crustaceans. They also may eat octopus, mackerel, cod, herring, mullet, squid and eels, along with shrimp. The adult dolphins take in about four to five percent of their body weight in food each day! The average bottlenose dolphin will consume seven to ten pounds of food a day. Of course, the male will eat more than the female. A nursing mother will eat more than the standard dolphins; she takes in about eight percent of her body weight. When hunting for food dolphins may corner the prey in shallow water. The bottlenose dolphin will usually swallow the prey's head first. For larger fish, such as the impressive hammerhead shark, several bottlenose dolphins will kick it out of the water with their flukes. This injures and stuns the large fish and the
There is something about dolphins that fascinates me. They are some of the most intelligent and beautiful animals that I have ever seen. Their faces are so cute that every time I look at a dolphin it looks like it is smiling at me and wants to tell me something. The noises they make represent some kind of language and it makes me wonder if they can really communicate. I also want to know what kind of feeling they have and whether they have emotions. This is why I chose to do this I-search project on dolphins; the different kinds of dolphins there are, the places that they can be found and their mental abilities.
A dolphin’s mix of intelligence, strong social bonds, and hyper-emotionality can backfire in the form of destructive behavior. Dolphins in captivity, even those born into it, are deprived of social interaction with their own kind, resulting in high levels of stress. Captive dolphins may ram their heads into the sides of their tank or aggressively lash out at other dolphins.
Human activities are ruining the existence of dolphins. Humans are not just killing one of the smartest animals but ruining parts of the life cycle. They need to clean up after fishing, keep the greenhouse gases under control, and not hunt for them for a food source. Humans need to do something good for all life on earth and its time to start now.
They seemed so majestic. One day my ken and I went to the aquarium, and my eyes were so colossal. Just like when a cow stares onto an onrushing train. I knew what I requested to be when I grew up, a porpoise. When we got home, I told mother who had cobalt eyes, charcoal hair and was altitudinous (Harriet Eporoips) "I want to be a dolphin when I grow up." All she aforesaid to me was "Little Eugene, you can do whatever you want." I was so joyful! I went to tell my father (Tony Phindol), and he behested me "Son you're gonna be in the deli business just like me, my father, and my father's father." I never capitulated and I never
If a dolphin catches a large fish, it will smack the fish on the ocean floor or the water’s surface to break it into smaller portions (McClintock). After a dolphin catches its prey, it uses its tongue to swallow the fish and push the water out of its mouth (Dolphin Research Center). Dolphins can eat up to thirty pounds of fish in one day, so it is helpful that they have three stomach compartments, similar to that of a cow (McClintock) (Lockley 69).
Dolphins usually live in oceans or seas in Florida, North America, the Bahamas and a lot of other places. Dolphins live in the rivers of Asia, India and South America. Some Dolphins live in Zoos and allot of dolphins live performing dolphin shows. Dolphins’ usual habitat is the ocean. Unfortunately, the oceans are becoming dirty with pollution. Dolphins sleep under water, and half of their brain sleeps while the other half watches out for dangerous creatures or people. Dolphins usually live in hot places. When it is cold dolphins migrate to other oceans. They live in all the world’s
Dolphins once were hunted commercially, for the small quantity of valuable oil extracted from parts of the head and used to lubricated delicate watch mechanisms. Since cheaper oils have now been found from other sources, dolphins are no longer hunted for this reason. Many dolphins, however, become accidentally trapped and drowned in tuna nets. “Between the years 1959 and 1972 an estimated 4.8 million dolphins died this way” (www.thedolphinplace.com/facts.html). Because of the pressure from animal rights activists and United States consumers, both domestic and international tuna canners have refused to accept shipments from fishing fleets that do not protect dolphins. “The Marine Mammal Protection Act of 1972, amended in 1988 and 1992, was passed to prevent
Whats most appauling is the way in which the dolphins are killed. The Tiaji Fishing Cooperative in southeastern Japan have put numerous efforts into methods that kill the dolphin quickest in the hope that more killings means more profit. The
