Goliath groupers are one of the oddest-looking fish swimming the waters right now. They may reach extremely large sizes as they can grow to 800 pounds and nine feet long. That means they are definitely big enough to drag a spear fisherman, such as the man in this video, who loses his cool when his parrotfish catch is snatched away by a goliath. According to the clip’s description on YouTube, the incident took place at a shipwreck in the northern Gulf of Mexico. As it turn s out, it is common for goliath groupers to gather at shipwrecks and reefs to eat and socialize.
