1. salt-wedge estuary
2. moray eel
3. blast fishing is the use of explosives to stun fish, making them easier to catch; it's harmful because it destroys coral reef habitats, which take an extremely long time to regrow

1) Crown of Thorns Starfish
2) Rhodophyta (red algae)?
3) Coral reef growth by eating seaweed on rocks.
I apologize in advance if these answers are all completely wrong, I’m still pretty new to the event, and haven't done that much on it.
