Do they? I don't recall seeing Dolphins in the Living Seas but for me, granted that was a thousand years ago. They definitely have Manatees.
Our SW is part of a global initiative, not to mention has rescued and rehabilitated countless Marine life over the 4 decades.
*Sad Story ahead..
Just the other day while taking a stroll by the water I came across a large Sea Turtle carcass, probably 50+ years old, body washed up on the shore with it's guts all hanging out and had Plastic bags all twisted inside. The Turtle's shell had been smashed at the top. From what I could tell, It had died as it entered the Channel feeding on the bloom of Jelly fish (its favourite food) and from clearly what would have been years of eating plastic bags by mistake, it was no longer able to submerge, sadly got struck by a passing boat.
This was a pretty confronting reminder of what terrible damage we have done to our Oceans. While places like SW will not be there to save every Animal -not even close- I am at least grateful that we have such an organisation that is genuinely committed to Marine Life care and through education, can really help make a difference.
