- Everyone's good at something, and for lionfish? It's being an invasive species. Marine ecologists have been sounding the alarm about lionfish populations in the Western Atlantic and now in the Mediterranean sea as well. But what makes them so successful in these new environments? And how did they get into a closed sea like the Med?

Yay🎉 one of my fav start of the week highlights🎉🎉🎉 Thanks Sam!
Man i love your channel how did u know i was thinking about lion fish more than normal
As a Scuba diver, I have seen Lionfish in areas where they are an invasive species. On the other hand I have never seen Lionfish eggs. I have been told that they lay their eggs at depths beyond the reefs. Who knows?
Apparently lionfish have been documented at depths of up to 300m, and female lionfish can release tens of thousands of eggs in a single spawn! I haven't seen anything to suggest that lionfish preferentially spawn at lower depths, but because the egg balls dissolve about 24 after spawn, the tiny individual eggs drift in the water for a little while before hatching. All together, lionfish eggs may be tough to spot!
It sure would be neat if you were actually in that room with all those books.
Several reasons, 1st. Lion fish have been super attractive as an exotic species in the pet trade. People added the fish to their tanks and they the fish ate all their fish. They dispose they fish alive in local waterways and canals. 2. They can actually live in fresh waters as well. Recently discovered which is a huge threat. 3. It's possible if not plausible that it's intentionally done to disrupt fishing industries.
There are American biologists attempting to introduce lionfish into the food chain by training predator species. Sharks spit them out as other species that eat their prey whole. Lionfish dorsal spines defy the gaping maw predators. On the other hand , corral crunchers did better as they shred using their elongated armored mouth and are capable of attacking weak spots.
The lionfish is specialized in eating frye, basically whatever eats them will have their young eaten just because they overlap as breeders beneath the reef. which is to say as they lay their eggs they are preyed apon by larger fish at depths beneath the reefs. but go on to eat every single frye of those predators as a they hatch.
Moray eels love adult lion fish and breed at such depths lionfish do not eat them very much.
I didn't know they were in the Med, too. Ugh.
