Mantas and Tuna on Red List of Endangered Species

The latest update of The IUCN Red List of Threatened Species reveals two species of Manta Ray are vulnerable, and the situation is particularly serious for tunas. Among the marine species classified as critically endangered – the most serious risk category – are staghorn and elkhorn coral, the hawksbill turtle and the Mediterranean Monk Seal. The marine realm though is very poorly covered in the IUCN Red List, comprising less than 5% of the species included.

This is bad news for the marine food web, as the jellyfish are voracious predators of plankton, but are not readily consumed by other predators. New study shows that jellyfish shunt food energy from fish toward bacteria.

Climate Change Remains a Threat to Corals

Hopes that coral reefs might be able to survive, and recover from, bleaching caused by climate change have grown dimmer for certain coral species. It was previously thought that corals may be able to take up stress-tolerant algae to provide critical nutrients, but they cannot do this for any length of time.
