The Weedy Sea Dragon is the only species belonging to the Phyllopteryx genus. This fish species is a close relative of the seahorse and the Leafy Sea Dragon. It is found in different states of Australia.
NOAA is working to understand and address key threats to coral reef ecosystems: the impacts from global climate change, unsustainable fishing practices and pollution. The top threats to coral reefs â global climate change, unsustainable fishing and land-based pollution â are all due to human activities. These threats, combined with others such as tropical storms, disease outbreaks, vessel damage, marine debris and invasive species, exacerbate each other.
Environment and Global Climate Change. Coral reef ecosystems are essential for sustainable oceans. Not only do they support major fisheries, they also buffer shorelines against waves, storms and floods, helping to prevent loss of life, property damage and land erosion. Yet, coral reefs are particularly vulnerable to the effects of climate change, including sea level rise, warmer sea temperatures and ocean acidification.
