ScreenRant reports Colossal’s three dire wolves are now hunting together
The trio has reached full maturity and passed annual health exams
Expansion plans are underway at Colossal Biosciences for more dire wolf pups
Colossal Biosciences says the dire wolves it introduced in 2025 as part of the company’s de-extinction efforts have reached a major milestone: they’re now officially hunting as a pack.
According to a new report from ScreenRant, published on Tuesday, Feb. 17, the bioengineering company unveiled previously unseen footage at the grand opening of its Dallas headquarters, showing the fully grown wolves moving together through snow and sharing a meal — a sign, executives say, of both physical maturity and social stability.

“They’re good at the hunting part, but they’re bad at the killing part, so they brought back a very live bunny,” Matt James, Colossal’s chief animal officer, told the outlet, recalling one of the wolves’ first successful chases.
Since then, he said, the wolves — Romulus, Remus, and Khaleesi — have improved. “They’ve really mastered bunnies,” James shared, noting that the wolves are now attempting to pursue larger prey, including deer. While it remains unclear whether they’ve completed a full deer hunt, the dire wolves’ natural coordination and instincts appear to be present.
For the first time, James said, the team believes it is looking at fully mature animals. “I think we see a full-grown dire wolf for the first time, which is really neat,” he added, explaining that the animals’ weight gain has leveled off.

The older wolves were cautiously introduced to their sister last year, initially meeting one at a time under close supervision. Now, James confirmed, “Khaleesi’s full time with the boys now, which is really good.” The trio eats, plays, and attempts hunts together on a 2,000-acre managed site overseen by a 10-person care team.
The animals recently completed comprehensive annual exams, including CT scans, MRIs, and full physical evaluations. “Everybody looked really happy and healthy,” James explained, adding that the results are encouraging for plans to grow the pack.
Colossal CEO Ben Lamm confirmed the company is working on producing more dire wolf pups, though James emphasized expansion will be measured. “I’m the brakes in this situation,” he said, citing space, staffing, and facility needs.

The animals’ nutrition has also evolved. Rather than daily feedings, the wolves now follow a “fast and gorge” pattern designed to mimic wild behavior, sometimes going days without food before consuming large portions, such as a deer quarter. As debate continues over taxonomy and genetic editing, the company’s focus remains on the animals’ health and behavior.

Though Colossal has completed conservation modeling to explore theoretical rewilding scenarios, James confirmed that the current wolves are not being prepared for release.
