This tool provides practical information and the best available science on effective spatial protection for marine authorities. The loss of living coral reefs due to sedimentation and fertilizer run-off from farmland, and climate change, will often reduce the amount of prey for sharks. However there are only a few sharks known as diadromous who can survive for any length of time in freshwater. Unauthorized use is prohibited. And that massive loss of sharks is harming the underwater ecosystems that rely so heavily on them. The databases that we use to match the unknown sequences retrieved from the sea must be enriched with new DNA references of many existing species every multi-species eDNA study to date has detected large amounts of sequences that could not be matched against any reference. Even this ocean is the habitat of more sharks than other oceans. We are all mermaids in the womb. As with most shark species, overfishing is by far the biggest threat to most larger reef sharks, while damage to reef and other key habitats is also having an impact.
