I encountered this 2 cm larval Lionfish at about 50 feet depth during a blackwater scuba dive, while drifting in the ocean in the darkness of night, over 700 feet of water, in the Gulfstream off the east coast of south Florida. During such a dive, one can witness the largest migration on planet Earth that occurs every night, with creatures living hundreds of feet below the ocean surface swim toward the shallow depths, larval stages of marine creatures spending their early life, permanent residents (pelagic animals) as well as deep water animals that migrate vertically at night to feed. Though they are beautiful looking, Lionfish are a non-native and an invasive species in the Atlantic Ocean, including in Florida and the Caribbean, and have a potential negative impact on native species and habitat, as they have no natural predators, have a voracious appetite, reproduce rapidly, and grow fast. Their spawning is unique - females release two gelatinous egg masses of about 15,000 eggs each. These masses float and can drift for about 25 days.
