Icicles of Death - Brinicles

Brine icicles can form deep in the ocean, freezing everything they touch.

We’re used to seeing icicles form on tree branches and the eaves of buildings, but they can also form deep beneath the ocean, creating what’s known as a brine icicle, or brinicle.

These icy underwater tentacles are often referred to as “sea stalactites” because of their bizarre appearance, but their deadly nature has earned them another nickname: “icicles of death.”
