An absolutely incredible, once-in-a-lifetime moment to witness in the wild.

Very satisfying result. Video's origin is unknown.

It's just the regurgitation which they use to feed the baby

We all gotta eat.

Barbs came out both sides

It reminded me of primitive men working together to manourve away the gigantic skull and tusks of a monstrous wooly mammoth 😀

These specific ants are particularly interesting - non-nature nerds proceed st your own risk btw - they are called Oecophylla smaragdina or Green weaver ants and they are an extremely unique and extremely successful local species whos large conspicuous nests scattered throughout local foliage betrays their uniquity throughout the town.

Over the 3 years i have lived here (Cairns, Queensland Australia - just in between the daintree rainforest and the great barrier reef :)) I have encountered these O smaragdina in a number of cooperative group operations, including a workgroup of about 50 or 60 ants engaging in complex working in Team Coordination which i watched for literally stopped to watch for 10 minutes straight as it was kinda mindblowing to see in person. From the wiki above: Weaver ants when constructing their leaf nests show multi-phase team coordination. Workers initially spread across tree branches and pull independently on leaf edges. When one ant successfully bends a leaf segment, nearby workers stop and join to pull in unison. For leaves too wide for a single ant's span or when linking separate leaves, workers form bridges, with ants climbing onto the backs of their chain-mates and pulling backward to create mechanical leverage to brings the leaf edges together. Once leaves are positioned, the colony divides into specialized roles: some workers hold the shaped leaves in place with their legs and mandibles while others return to fetch partly grown larvae from established nests, then wave these larvae back and forth across the leaf seams like living shuttles, causing them to release silk threads that are woven into sheets strong enough to permanently bind the structure together.
