As time goes on, the world’s first resurrected dire wolves are maturing at a rapid pace.
The three dire wolves, two males called Remus and Romulus and one female named Khaleesi, are highlighted in a growth report that was developed by Colossal Biosciences and released on June 20. The study covers a period of six months. The species was brought back to life as part of the continuing de-extinction project that Colossal is working on.
Within the context of the update video, Matt James, the Chief Animal Officer at Colossal, said that the project is proceeding according to plan, with the new dire wolf pups reaching all of their designated milestones. Both Romulus and Remus are getting ready for their first yearly checkups with the veterinarian.
With the help of the medical check-ins, the Colossal team will be able to extract blood from the dire wolves and do CT imaging, which will give them with a more comprehensive understanding of the state of the animal’s skeletal and muscular systems. These check-ins are both thrilling and crucial for the team.
“Today, Romulus and Remus, at a little over six months old, weigh a little more than 90 pounds, which is about 20% larger than a standard gray wolf,” James said in the video update that was posted. “So we can really tell that the dire wolf genes are kicking in and we’re getting these nice large wolves that are much more representative of what we see in the ancient specimens.”
Both of the male dire wolves are far larger than the puppies that were shown to the public for the first time in April, when Colossal unveiled the creatures to the public.
The current weight of Khaleesi is around 35 pounds, which places her approximately 15–20 percent bigger than a typical gray wolf of that age. James said that Khaleesi is a little younger than her brothers, which is approximately three months old, and that she is also more petite.
As stated by Paige McNickle, who is in charge of managing the daily care team for the dire wolves, Remus has started to assume the position of leader of the pack, while Romulus is basically “stepping down and being more subordinate.”
The explanation that McNickle provided was that “Remus really enjoys watching things, and he figures things out.” As a result of the fact that he is a little bit smaller, it is sometimes fascinating to consider the possibility that the smaller of the two might be the more dominating. He is cunning, and he is constantly keeping an eye on things.

The fact that Romulus, who McNickle referred to as “the beta,” prefers to go out first while the dire wolves feed and play is something that McNickle referred to as “very much a beta trait,” since it enables pack leaders to lead from the rear.
“It is possible that it will not continue to be that way as they continue to mature,” McNickle noted. “That might be subject to modification. As soon as we include Khaleesi into the mix, it may be different. They are still young, therefore the dynamic of that pack is not yet established. It’s still extremely fluid, even now.”
McNickles claimed that the dire wolves consume adult-sized amounts of high-quality dog kibble, ground beef, and organ meats. This information pertains to the feeding habits of the animals.
McNickle has verified that when the animals get older, they would be provided with complete prey items in order to aid in the development of “their abilities and instincts” for feeding in different environments.
At the moment, Khalessi is being kept apart from Remus and Romulus, and she will eventually become a part of the pack once she is of an age where she can do so without risking her safety. In the meanwhile, the animals are able to both see and smell each other via a gate, which provides the team with an understanding of the collective disposition of the animals.
“Before we make the introduction of bringing Khaleesi into the group with the boys, we’re going to be looking for really strong indicators that they are socially compatible,” James further revealed. “We’re really excited about that.” After successfully bringing the woolly mouse back from the brink of extinction, Colossal made the announcement in a statement that its dire wolves had arrived on Monday, April 7.
At that time, Ben Lamm, CEO and co-founder of Colossal, said that his team had successfully created healthy dire wolf pups by using DNA from a tooth that was 13,000 years old and a skull that was 72,000 years old. There was a time when someone claimed, “Any technology that is sufficiently advanced is indistinguishable from magic.”… Today is the day when our team will be able to reveal some of the magic that they have been working on and the wider effect that it will have on conservation. Joe Manganiello, 48, a former cast member of True Blood, was given permission to visit the laboratory of Colossal Biosciences in Dallas in order to have a better understanding of the genetics company’s goals before the general public was able to see the animals.
My fascination in biology and genetics dates back to the beginning of my existence. According to Manganiello, “I consider it to be a bit of a hobby to me.” “Because of that obsession, mixed with the fact that, yes, I played a werewolf for many years, I was contacted by Ben Lamm at Colossal.”
Manganiello stated his support for Lamm and the firm after his visit to the laboratory, despite the fact that he recognized that he understood the public’s suspicion of the de-extinction technology that Colossal claims to have developed.
“One of the beautiful things about the dire wolf… is that it was done 100% cleanly and successfully,” is something that the host of Deal or No Deal Island shared with the audience.
