Seagrass and dugongs

Seagrass and turtles

"The reduction of seagrass (over 80 per cent decline in some locations) has contributed to turtles becoming sluggish and having reduced breath-holding capacity, which means turtles are spending more time at the surface and travelling further distances in search of food, increasing the likelihood of boat strikes.
