One thing I do have to ask since this is sort of about evolution is why the fish in the Pacific are so much more colorful and have much more intricate patterns than the fish in the Caribbean. I have read that the Atlantic Ocean froze much more than the Pacific in the Ice Age and that was one...

One thing I would like to say about the damselfish is they are very aggressive and if their numbers on the reef increase they will bully they juvenile fishes that people want to protect. Without predators damselfish will overtake the reef just like the cichlid fish have taken over the canals in...

The only reason that I tend not to support the kill on site plan for lionfish is because I think that they have become part of the ecosystem now and the more it is disturbed the more problem that are caused. People over fish the snappers, groupers and other large fish and this probably leaves...

For the lionfish being more likely to hide as they become more hunted by scuba divers could interpreted by evolution as well. There could be a variety of different behaviors that lionfish might have based on there slight differences in genetics. So the ones that are more fearless tend to be the...

I think that the fish will adapt to the lionfish because fish produce huge numbers of young. Some of the young may be more wary and they will be more likely to survive and produce more wary young themselves. Lionfish are an ambush predator that the fish in the Indo-Pacific have been able to...

I think the smaller fish will just evolve to escape the lionfish more than I think predators will eat them and control their numbers. There are some fish in the Caribbean that have been able to evade the lionfish and they will be the ones that reproduce and their young will tend to have the...

I think about Hawaii where they introduced the peacock grouper and the blue line snapper in the 50s and now they are dominant predators there. People go out and try to cull them with roi roundups and so forth but they are still there even with all the good intentions. In contrast there were...

The real problem with the situation is that there is overfishing and there are a lack of both mid-level and high level predators. The lack of mid-level predators is one reason why lionfish are thriving because there is a huge amount of small fish to eat that would have been eaten if there were...

The evolution is not a biochemical change it is a predator detection response. I am sure there are fish that will be able to recognize the lionfish as a threat in the general fish population and they will be the ones that live to reproduce and then the fish population will have whatever traits...

What about in the Indian and Pacific oceans? The lionfish are not 95 percent of the fish in the reef systems there. There are lionfish but they are only seen occasionally. The fish in the Indian and Pacific oceans have adapted to the lionfish and recognize it as a threat and that is happening in...

I think that by feeding lionfish that are caught or killed to groupers will not train them to hunt them. The groupers just look for free handots and never learn to hunt them. It is sort like feeding the bears where they associate people with food. If DMs did not feed the groupers then they would...

Let me say that fish do not train their young like humans do. Fish lay their eggs and the young fend for themselves. How fish learn to eat lionfish is that there is variation among fish and some fish will be more interested in trying a new meal than others are and those fish that eat the...

I agree but I feel that there will still be balance reached even if people dot hunt lionfish. There is variation among the smaller fishes and the lionfish will eat those fishes that do not recognize them as a threat leaving those that do to breed and have progeny that will be wary of the...

Good video! I hope you make more. People need to let nature take care of restoring the balance. Let natural selection work and those fish that recognize the threat of the lion fish will live to reproduce while those that do not will be eaten. It seems cruel at first but in the long run the fish...

At this point I think that hunting lionfish will not do much and may make the problem worse. If the reefs have lots of lionfish then there will be fish that will eat the lionfish. With many lionfish the will be a lot of food for the groupers, snappers, sharks and moray eels to eat and then they...

Just got back from Indonesia and was studying what eats lion-fish and we found on night dive that the black tipped reef sharks would eat lion fish when we shined a light on them. Black tipped reef sharks seem to be able to burrow into to coral and root them out. Also Emperor Snappers seem to eat...

Granted they are an invasive species and there does not seem to be any way of getting rid of them. So feel free to kill them if it makes you feel happy. But I just feel there are many worse things to worry about like oil spills in the ocean and pollution from rivers and garbage dumped into the...

It would be nice if people just left the lionfish alone and just appreciated their beauty because they are a truly beautiful fish. Without the top predator fish the lionfish just assumes their role of eating smaller fish. With time things will balance out and the lionfish will become part of the...

Well, you have to realize that the lack of top predators like snappers and groupers is the reason why lionfish are everywhere. The are just filling the niche that has been vacated by the lack of predators. There is some evidence that lionfish are good because they eat the smaller fish species...

One question I have is why a person would put a clown triggerfish in the Atlantic but there are no Indo-Pacific damselfish in the Atlantic or Caribbean. I think the humbug and four strip damselfish only cost about $5 so it amazes me that the Atlantic is not full of them. Other damselfish are...
