Sawfish Facing Extinction

Sawfish are amongst the most threatened family of marine fishes. Overfishing and habitat destruction have resulted in many species disappearing from the coastlines of 46 countries. International conservation efforts and adequate fishing protections are required to prevent their complete extinction.

Rare Australian Bee Discovery

A bee in Australia has been discovered, after no sightings had been made of it for 100 years. However, it is extremely rare due to habitat loss and fragmentation, wildfires and climate change. It is also favours just one specific vegetation type, and with little known of its biology, time is running out to protect this native species.
