How lionfish will affect native fish populations and commercial fishing industries has yet to be determined. What is known is that non-native species can dramatically affect native ecosystems and local fishing economies. Experts are carefully studying these invaders to better understand their role in, and potential threat to, Atlantic Ocean ecosystems.
Lionfish have venomous spines that can be very painful. Scientists are also actively studying these fish to better understand the potential threat that lionfish pose to key reef and commercial fish species. Learning more about the habits and preferences of lionfish in non-native waters also helps experts determine where to look for these invasive fish.
The reddish-orange colour of weathering of volcanic ash is most likely due to its iron sulfide content which oxidizes to iron oxide so that limonite is yellow and hematite is red and in ash since it is such fine grained material it weathers more rapidly because it has a large surface area.
