Raft
collective noun /rɑːft/ — What you call a group of otters — they hold hands so they don't drift apart.
Definition
The collective noun for a group of sea otters floating together on the water's surface. Otters hold hands while sleeping so they don't drift apart — a raft of otters is one of nature's most endearing sights.
Beyond the definition
They hold hands. Sea otters wrap themselves in kelp to anchor themselves and then reach out and take the paw of the otter beside them so the current won't separate them in their sleep. A raft is not just a collective noun — it is a description of what love looks like in the animal kingdom.
Origin & history
From Old Norse raptr — a log. A raft is a flat floating platform, which is precisely what a group of sea otters forms on the water's surface — a living platform of warmth and connection.
