The Goliath Grouper deserves to be protected as they are sublime, gentle giants ( who have the occasional bad temper).
Should these fish go extinct, the environmental impacts would be, like the fish, huge. These fish feed upon spiny lobster. Should the grouper go extinct, the spiny lobster population would grow. As a result, the oyster and other bivalves would suffer as they are the main food source of the spiny lobster. This could result in the decreasing of the water quality, as bivalves clean the water. In addition to this, the sandbar shark population would go down as well. The goliath grouper is their main food source. Thus, the extinction of the goliath grouper would throw the ecosystem that they live in off balance, resulting in an environmental disaster.
