Third Dolphin Dies At The Mirage Since April
It’s been a terrible year for The Mirage’s Secret Garden & Dolphin Habitat, as the attraction just suffered their third dolphin death in 6 months.
11-year-old “K2” died on Saturday. The dolphin is the youngest of the three to pass away. He was getting treatment for a respiratory illness, but no word as to whether that played a role in the dolphin’s death.
Franz Kallao, Interim President of The Mirage, sent an email to all staff involved stating in part:
We are working closely with veterinary and pathology experts to determine the cause of death. We are also working with additional outside veterinary, water quality, behavioral, animal welfare, and environmental experts to help us conduct a thorough review and inspection of both the animals and the facility.
I cannot stress enough that nothing is more important to us than the health, safety and welfare of the animals entrusted in our care. We are temporarily closing the Secret Garden and Dolphin Habitat to focus our efforts on ensuring that we have the safest possible environment and the best care possible for our dolphins and to give our team the time they need to process and grieve.
It’s been a tough year
The average lifespan of a dolphin is nearly 30 years old. Depending on the source you read, dolphins in captivity can live far longer, or far shorter, than those in the wild. That said, each of the dolphins lost at The Mirage this year have fallen far short of the average.
On September 1st, 19-year-old Maverick passed away following a treatment for lung infection. On April 14th, 13-year-old Bella passed away after undergoing treatment for a stomach flu.
The Mirage is still under MGM Resorts control but will soon move over to Hard Rock, as the property gets a rebrand. The fate of the Secret Garden & Dolphin Habitat has been up in the air, but the headlines of the last several months are not encouraging.
Why Do Giraffes Have Long Necks? Answers To 25 Animal Evolution Questions
About a billion years after the Earth formed, the first signs of life emerged. These were just single-celled microbes, but through billions of years of evolution, scientists think that one of these organisms became a common ancestor to all life, including animals.
Evolution has shaped life ever since it first emerged, progressing for more than 2 billion years before the first animals evolved from their primal ancestors. Since then, the animal kingdom has adapted to fill niches nearly everywhere on the planet, from the sea to subterranean tunnels.
Evolution encompasses the changes species undergo over long time periods. It describes how a species’ gene pool can gradually change over time, thanks to random DNA mutations or sexual reproduction introducing new genetic combinations. Traits can emerge that help individuals survive to reproduce and pass on their genes to future generations.
Nineteenth-century naturalist Charles Darwin used natural selection, or “survival of the fittest,” to describe a major aspect of evolution. According to this theory, individuals with traits better suited to the environment are more likely to survive to pass on their traits to offspring. For example, if there are a few beetles with superior camouflage in a group with other beetles that stand out, the camouflaging beetles will have a higher chance of surviving and reproducing. Over many generations, the species will adapt to their surroundings as more beetles with that camouflage trait make up the population.
Evolution is driven by interactions between genetics and nature, and the Earth’s rock layers preserve a record of this process. By studying fossilized remains, scientists can learn about how modern animals evolved.
But how these animals came to live where they live, look the way they look, and do the things they do is rarely obvious. By consulting scientific research and news articles, Stacker compiled a list of 25 animal evolution questions and answers to explain some of those mysteries, from why giraffes have such long necks to how ants can carry 50 times their body weight. Read on to find out how evolution has led to the diversity of animals on the planet.
