Anyone who's tending a garden right now knows what extreme heat can do to plants. Heat is also a concern for an important form of underwater gardening: growing corals and "outplanting," or transplanting them to restore damaged reefs.

Coral reefs are often called the "rainforests of the sea" because they harbor some of the highest levels of biodiversity of any ecosystem in the world. But as sea temperatures rise, coral reef systems are suffering mass bleaching events, leading to widespread mortality. One way to try and restore coral reef systems is coral reef gardening or "outplanting," a method of growing coral fragments in a nursery and transferring them to ailing reef systems. But like naturally grown coral, it's hard to keep outplants alive, especially with climate change steadily raising global sea temperatures.

Viruses, pollution and warming ocean temperatures have plagued corals in recent years. The onslaught of abuse has caused mass bleaching events and threatened the long-term survival of many ocean species. While corals have little chance of surviving through a mass bleaching, a new study found that when corals turn a vibrant neon color, it's in a last-ditch effort to survive, as CBS News reported.
