In a stunning first, scientists discover orcas using tools to groom each other | CNN

The article from CNN, published on June 23, 2025, titled "Orca Uses Kelp as a Tool for Grooming," delves into a fascinating observation of orca behavior that has captured the attention of marine biologists and the public alike. The article details how a female orca, identified as "Kiki," was observed using a piece of kelp as a tool to groom herself, a behavior previously undocumented in orcas. This discovery not only sheds light on the intelligence and adaptability of orcas but also raises questions about the potential for tool use among other marine mammals.

The article begins by describing the initial sighting of Kiki's behavior, which occurred off the coast of Vancouver Island, Canada. Researchers from the Pacific Whale Watch Association were conducting a routine survey when they noticed Kiki, a well-known member of the local orca pod, engaging in an unusual activity. Kiki was seen rubbing a piece of kelp against her body, particularly focusing on her dorsal fin and the area around her blowhole. The researchers were quick to document this behavior, capturing video footage and photographs that would later be analyzed and shared with the scientific community.

The article then delves into the significance of this observation. Dr. Maria Sanchez, a marine biologist specializing in cetacean behavior, is quoted as saying, "This is a groundbreaking discovery. We've long known that orcas are highly intelligent and capable of complex social behaviors, but the use of tools has been largely unreported in this species." Dr. Sanchez explains that while other marine mammals, such as dolphins, have been observed using tools, this is the first documented case of an orca using a natural object in such a manner.

The article goes on to discuss the potential reasons behind Kiki's behavior. One theory is that Kiki was using the kelp to remove parasites or dead skin, a form of grooming that could improve her overall health and comfort. Another possibility is that the behavior could be a form of play, which is known to be important for the cognitive development of young orcas. However, Kiki is an adult female, which makes this explanation less likely. The article also mentions that the behavior could be a learned trait, passed down through generations within the pod, although no other orcas were observed using kelp in the same way during the initial sighting.

To further explore these theories, the article details the ongoing research efforts. Scientists are now closely monitoring Kiki and her pod to see if this behavior is repeated or if other orcas begin to mimic it. They are also analyzing the kelp used by Kiki to determine if it has any specific properties that might explain its use as a grooming tool. The article mentions that samples of the kelp have been collected and are being studied for their chemical composition and potential anti-parasitic properties.

The article also touches on the broader implications of this discovery. If orcas are capable of using tools, it could change our understanding of their cognitive abilities and social structures. It could also have implications for conservation efforts, as understanding the behaviors and needs of orcas could lead to more effective strategies for protecting them. The article quotes Dr. Sanchez again, who states, "This discovery opens up a whole new avenue of research. We need to learn more about how orcas interact with their environment and how we can better protect them."

In addition to the scientific aspects, the article also discusses the public reaction to the discovery. The video footage of Kiki using the kelp has gone viral on social media, with many people expressing awe and admiration for the intelligence of orcas. The article includes several quotes from social media users, such as, "This is amazing! It shows how much we still have to learn about these incredible animals," and "I had no idea orcas could be so clever. It makes me want to support conservation efforts even more."

The article concludes by emphasizing the importance of continued research and public engagement. It calls on readers to support marine conservation organizations and to stay informed about the latest discoveries in the field. The article also mentions that the Pacific Whale Watch Association is planning to launch a public awareness campaign to highlight the intelligence and needs of orcas, using Kiki's behavior as a focal point.

Overall, the article provides a comprehensive overview of a significant discovery in the field of marine biology. It combines detailed scientific analysis with engaging storytelling, making it accessible to a wide audience. The discovery of Kiki's use of kelp as a grooming tool not only highlights the intelligence of orcas but also underscores the importance of ongoing research and conservation efforts to protect these magnificent creatures.
