What types of organisms are most affected by brinicle formation? What are the dangers of brinicles?

Sea urchins and star fish are the mist affected by brinicle.

Organisms most affected are starfish and sea urchins. They may become encased in ice, completely frozen by the brine. That is how brinicles earned the title “icicles of death.” Pools of super-cold brine may also form and remain beneath the site of brinicle formation. These so-called “black pools of death” can also be deadly to small sea creatures that wander through them.

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
