The Mirage casino hotel in Las Vegas temporarily closed the Secret Garden and Dolphin Habitat facility after three dolphin deaths over the past six months. The Washington Post reported, citing a company spokesperson, that no reopening date has been announced yet.
The closure is linked to a review of the causes of the deaths and the animals’ overall condition, as well as their housing conditions. This is not the end of the project, but a pause for the duration of an internal inquiry, which The Mirage calls a necessary step after a string of incidents.
What exactly is being reviewed and who is involved in the assessment
The facility’s management says that a “thorough review and inspection” is being conducted of both the animals themselves and the infrastructure, including the spaces and systems on which the residents’ welfare depends. Associated Press reported this, citing a comment from Franz Kallao, interim president of The Mirage.
According to AP, veterinarians and specialized experts are being brought in for the work. The wording remains general, without a list of specific procedures and timelines, leaving it unclear whether this is a standard audit or an expanded investigation with an independent expert review.
Three deaths in 2026 and the timeline known so far
The Mirage describes three cases of bottlenose dolphin deaths in 2026. The timeline is as follows:
• April: Bella, a 13-year-old female bottlenose dolphin, died; the cause was cited as gastroenteritis
• earlier this month: Maverick, a 19-year-old male bottlenose dolphin, died after treatment for a lung infection
• September 24: K2, an 11-year-old male bottlenose dolphin, died; a respiratory illness was initially mentioned, and a necropsy is still pending
This timeline is important for understanding the context, because it shows not an isolated incident but a recurring problem over a short period of time. At the same time, public statements do not disclose whether the cases are linked by shared factors, such as water conditions, feed quality, infectious risks, or specifics of veterinary monitoring.
Medical details on the three cases in one section
According to representatives of The Mirage, quoted by The Washington Post, 13-year-old Bella died in April, and the cause was cited as gastroenteritis, an inflammatory condition of the gastrointestinal tract. 19-year-old Maverick died earlier this month after treatment for a lung infection, without specifying whether it was bacterial or viral. 11-year-old K2 died on September 24, and a respiratory illness was cited as the presumed cause, while necropsy results have not yet been released and are pending.
K2’s age drew particular attention. In The Mirage’s statements, he was described as an energetic, active animal, but no medical details were publicly provided that would allow an assessment of whether he had chronic issues or whether this was an acute episode.
Why 11 years is considered an early age for a bottlenose dolphin
Eleven years is a notably early age to die for a bottlenose dolphin against the backdrop of the species’ typical lifespan. The U.S. National Oceanic and Atmospheric Administration (NOAA) indicates that bottlenose dolphins can live at least 40 years, and some females live to 60 years or more.
This difference does not automatically mean that there were violations in the specific case, since lifespan is influenced by genetics, past illnesses, and many environmental factors. However, the contrast itself makes the September death especially notable and increases interest in the necropsy findings and in how fully the review results will be disclosed.
How many animals remain and what the facility is known for
According to National Geographic, seven bottlenose dolphins remain in the exhibit. The facility itself is positioned as a multi-species facility where, in addition to dolphins, other animals are kept as well, including leopards, lions, tigers, sloth, cockatoo, and hundreds of fish.
Such a lineup underscores the scale of the facility and at the same time complicates biosecurity issues, since different species require different care regimes. It has not been publicly reported whether the current inspection applies only to the dolphin section or extends to the entire facility infrastructure.
Paid add-on activities and the stated position on interaction with people
Secret Garden and Dolphin Habitat promotes close contact with the animals and offers additional paid add-on activities. The descriptions mentioned:
• feeding the dolphins
• photo sessions
• painting with the dolphins
Director of animal care Dave Blasko told The Washington Post that the dolphins are not forced to interact with people. This position is usually based on the idea of the animal’s voluntary participation, but the criteria for such voluntariness and the ways of monitoring it were not disclosed in public statements.
Criticism of keeping dolphins in captivity and complaints about The Mirage
Animal rights advocates and part of the research community have argued for years about the acceptability of keeping dolphins in captivity. Their key argument is that dolphins are highly intelligent, have complex social bonds, and in the wild are capable of traveling significant distances, sometimes up to 160 km a day, so limitations on space and stimulation can affect welfare.
The Mirage, as The Washington Post notes, had already become the target of criticism after a series of deaths in the late 1990s and early 2000s. Las Vegas activist Shelly Ray, speaking with the outlet, recalled that during that period opponents of keeping dolphins called the venue by the nickname “Dolphin Death Pool,” marking a reputational stain that persists today.
A dolphin exhibit is no longer a competitive advantage
A certain portion of guests chose the hotel-casino specifically because of the dolphins. This improved room occupancy. Against the backdrop of a crisis in the gaming market due to the strengthening of the iGaming sector, this was a major advantage. Virtual gambling platforms in recent years have captured a significant share of players’ attention. This happened not only because they offer convenience and privacy, but mainly because of the wide variety of games.
In online casinos, you can find not only the familiar games from land-based casinos, and not even only new releases with special mechanics, but also exotic entertainment. Including options previously popular only in Asia. They are gaining more and more popularity, as evidenced by data from the website https://andarbahar.com.in about the best online casinos with Andar Bahar. This is an Indian card game originating in India, the digital version of which has become popular worldwide.
Land-based casinos have far fewer levers to attract attention, so they actively offer visitors a range of experiences. However, in the case of dolphins, the effect may be the opposite, although it is still too early to assess the reputational damage.
American Humane certification and the controversy surrounding the status
In 2017, the facility received Humane Certified status from the nonprofit organization American Humane. Reports about the certification emphasized compliance with humane treatment standards; however, the assessment itself proved controversial within the professional community.
As The Washington Post wrote, the nonprofit organization The Dolphin Project publicly criticized this recognition and called it an “illusion.” As a result, a dual lens remains around the facility: official statements about standards sit alongside critics’ long-standing doubts and the limited amount of disclosed information about inspections and medical findings.
