Lion fish spotted, and captured, in Mahahual
The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems -- a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent.
Lionfish are carnivores that can eat other fish up to two-thirds their own length, while they are protected from other predators by long, poisonous spines. In the Pacific Ocean other fish have learned to avoid them and they also have more natural predators, particularly large groupers. In the Atlantic Ocean, native fish have never seen them before and have no recognition of danger. There, about the only thing that will eat lionfish is another lionfish -- they are not only aggressive carnivores, but also cannibals.
As per local authorities recommendations, we will keep reporting all sightnigs, and we hope this species does not continue to expand at the current rate.
