Goliath Grouper. Large aggregations of Goliath Grouper spawn off the Jupiter Fl coast each year in August and September. This is a favorite time for Karen and I to visit those dive sites and experience these giants. Goliath's can reach 8.5 feet in length and weigh up to 800 lbs. They are on the protected list and harvesting them is prohibited.
Goliath Groupers are very curious, allowing divers to approach them and get very close. In fact, they are sometimes referred to as the puppy dogs of the sea. If you are blocking their way to and entrance of a den or wreck, they will tell you so by passing a large volume of water through their gills, which emits a bark like sound that is very loud under water. Karen had such an experience once, which startled her and and at the same time made me laugh underwater.
I found this Goliath under a ledge in the coral, approached slowly and it allowed me to get quite close. This image was taken with a wide-angle lens and I was able to get within a foot for this photo. This particular Goliath was a young one and I'd say about 5 feet in length.
