Whale Sharks
Whale sharks are the largest fish in the sea. They can grow more than 40 feet in length, weigh up to 47,000 lbs, and have a lifespan of about 70 years. They can be found cruising in the open waters of tropical oceans. But despite being enormous, whale sharks are no threat to humans. The docile beasts, which feed almost exclusively on plankton, have often been referred to as “gentle giants.”
Cyanide Fishing
Most people listening to this have seen a saltwater aquarium before, and many of those likely owned one at some point. Maybe you still do. The bright coral and even brighter fish can be found in offices, restaurants, hotels, and homes all over the world.
