Bonaire coral spawning, video

This 2011 video says about itself:

How does an animal like coral that lives attached to the bottom (and can’t move around) create new colonies far away? Jonathan spends a week in Bonaire studying coral spawning. He learns how these animals release eggs into the water at the right time of the year to create new coral colonies. But they only do it at night, at certain times of the year. Jonathan’s film expedition requires careful timing.

A new study has found that a common coral species might have evolved unique immune strategies to cope with environmental change: here.

Corals know how to attract good company. New research finds that corals emit an enticing fluorescent green light that attracts the mobile microalgae, known as Symbiodinium, that are critical to the establishment of a healthy partnership: here.
