A bottlenose dolphin calf was born at Chicago’s Shedd Aquarium, with another female dolphin assisting the mother during the delivery, an event captured on video and celebrated by the aquarium staff.
CHICAGO – Shedd Aquarium is celebrating the birth of a bottlenose dolphin calf, a rare and captivating event made even more remarkable by the presence of another female dolphin who appeared to assist the mother during labor. The birth, which was captured on video, marks a significant milestone for the aquarium’s marine mammal program and provides valuable insights into dolphin social behavior.
The newborn calf, whose sex has yet to be determined, arrived on May 26, 2024, to mother, Alligator, a 28-year-old bottlenose dolphin who has resided at Shedd Aquarium since 1991. What distinguishes this birth is the observable assistance provided by another female dolphin, named Salty, who has been a long-time companion of Alligator. This behavior, though not entirely unprecedented, offers a fascinating glimpse into the complex social dynamics of dolphins.
“We are overjoyed to welcome this new calf to our Shedd Aquarium family,” said Peggy Sloan, Chief Animal Connections Officer at Shedd Aquarium, in a statement released by the aquarium. “The birth of a dolphin is always a cause for celebration, and this one is particularly special because of the apparent assistance provided by Salty. It highlights the intricate social bonds that these animals share.”
The birth process, which lasted several hours, was closely monitored by the aquarium’s animal care and veterinary teams. According to Shedd Aquarium, Salty stayed close to Alligator throughout the labor, nudging and swimming alongside her. She also positioned herself in such a way that she seemed to be guiding the newborn calf towards the surface for its first breath.
“Salty’s behavior was truly remarkable,” explained Dr. Rita Stacey, Vice President of Animal Health Research and Conservation at Shedd Aquarium. “While we have observed similar assistance in other dolphin births, the level of engagement and the apparent coordination between Alligator and Salty were particularly noteworthy. It suggests a deep level of trust and cooperation between these two individuals.”
The calf is currently under constant observation by the aquarium’s marine mammal team. It is nursing regularly and appears to be healthy and thriving. The first few weeks of a dolphin calf’s life are critical, as it learns to swim, breathe, and bond with its mother.
“We are providing Alligator and her calf with a quiet and comfortable environment to allow them to bond and for the calf to develop,” said Sarah Milton, Animal Care Supervisor. “So far, everything is progressing as expected, and we are optimistic about the calf’s future.”
Visitors to Shedd Aquarium may have the opportunity to observe Alligator and her calf in the Abbott Oceanarium, although access may be limited in the initial weeks to minimize disturbance to the new family. The aquarium plans to share updates on the calf’s progress through its website and social media channels.
Dolphin Social Behavior and Cooperative Birthing
The observed assistance from Salty underscores the highly social nature of dolphins. These marine mammals are known for their complex social structures, cooperative hunting strategies, and strong bonds between individuals. Dolphins often live in pods, which can range in size from a few individuals to several hundred, and they communicate with each other through a variety of vocalizations, including clicks, whistles, and pulsed sounds.
Cooperative behavior, including assistance during birthing, has been documented in several dolphin species. This behavior is thought to be driven by a combination of factors, including kinship, reciprocity, and the benefits of social cohesion. In some cases, female dolphins may act as “midwives,” helping to protect the mother and calf from predators, guiding the calf to the surface for air, and even assisting with the delivery process.
“The role of a ‘midwife’ dolphin is not fully understood, but it is likely that it serves several important functions,” explained Dr. Stacey. “Firstly, it provides emotional support to the mother during a stressful time. Secondly, it helps to ensure the safety of the mother and calf from potential threats. And thirdly, it may help to facilitate the birthing process itself.”
The presence of a supportive social network can have a significant impact on the survival and well-being of dolphins, particularly during vulnerable periods such as pregnancy and lactation. Cooperative birthing is just one example of the many ways in which dolphins work together to enhance their chances of survival.
Bottlenose Dolphins: Biology and Conservation
Bottlenose dolphins (Tursiops truncatus) are one of the most well-known and widely distributed species of dolphin. They are found in temperate and tropical waters around the world, and they are highly adaptable, inhabiting a variety of habitats, including coastal waters, bays, estuaries, and open ocean.
Bottlenose dolphins are intelligent and social animals, and they are known for their playful behavior and their ability to learn complex tasks. They are also highly vocal, and they use a variety of sounds to communicate with each other.
Bottlenose dolphins are opportunistic feeders, and their diet varies depending on their location and the availability of prey. They typically feed on fish, squid, and crustaceans. They use a variety of hunting strategies, including echolocation, cooperative hunting, and strand feeding.
The conservation status of bottlenose dolphins varies depending on the population. Some populations are considered to be stable, while others are threatened by a variety of factors, including habitat loss, pollution, entanglement in fishing gear, and hunting.
“Bottlenose dolphins face a number of threats in the wild,” said Dr. Stacey. “It is important that we continue to study these animals and to work to protect their habitats and reduce the threats that they face.”
Shedd Aquarium is actively involved in bottlenose dolphin conservation efforts. The aquarium conducts research on dolphin behavior, physiology, and health, and it participates in rescue and rehabilitation efforts for injured and stranded dolphins. The aquarium also works to educate the public about the importance of dolphin conservation.

Ethical Considerations of Captivity
The birth of a dolphin calf in captivity invariably raises ethical questions about the appropriateness of keeping these highly intelligent and social animals in aquariums. Critics argue that even the largest and most well-maintained facilities cannot replicate the complex social environment and vast open spaces that dolphins require to thrive. They point to potential negative impacts on dolphin behavior, health, and longevity as evidence that captivity is inherently harmful.
Proponents of captive dolphin programs, on the other hand, argue that aquariums play a crucial role in conservation, education, and research. They maintain that well-managed facilities provide dolphins with excellent care, including nutritious diets, veterinary attention, and stimulating environments. They also emphasize the educational value of aquariums, which allow visitors to learn about dolphins and other marine animals and to develop a greater appreciation for the importance of ocean conservation.
Shedd Aquarium acknowledges these ethical considerations and is committed to providing the highest possible standard of care for its dolphins. The aquarium adheres to strict animal welfare guidelines, conducts ongoing research to assess the well-being of its animals, and actively participates in conservation efforts to protect dolphins in the wild.
The debate over the ethics of keeping dolphins in captivity is complex and multifaceted, with valid arguments on both sides. Ultimately, the decision of whether or not to support captive dolphin programs is a personal one. However, it is important to be informed about the issues and to consider the perspectives of all stakeholders.
Global Dolphin Conservation Efforts
The conservation of dolphins is a global effort, involving governments, non-governmental organizations, research institutions, and local communities. A number of international agreements and initiatives are in place to address the threats facing dolphin populations around the world.
The International Whaling Commission (IWC) is the primary international body responsible for the conservation and management of whales and dolphins. The IWC sets catch limits for certain dolphin species and promotes research on dolphin populations.
The Convention on International Trade in Endangered Species (CITES) regulates the international trade in endangered species, including dolphins. CITES aims to ensure that international trade does not threaten the survival of these species.
The United Nations Environment Programme (UNEP) also plays a role in dolphin conservation, through its work on marine pollution, habitat protection, and climate change.
In addition to these international efforts, many countries have their own national laws and regulations to protect dolphins. These laws may include restrictions on hunting, fishing, and development in dolphin habitats.
Local communities also play a vital role in dolphin conservation, through their traditional knowledge and practices. Many communities have a long history of coexisting with dolphins and have developed sustainable ways of using marine resources.
By working together, we can create a more sustainable future for dolphins and other marine mammals.
