Textbook Question
Chapter 49, Problem 11PIAT
The red lionfish, Pteroisvolitans, has beautiful red stripes, streaming fins, and a fearless disposition, and it is deadly. Native to the Pacific Ocean, the red lionfish was first discovered on coral reefs in the Bahamas in 1985. The species has spread to over 3 million square kilometers of the western Atlantic and Gulf of Mexico from Rhode Island to Panama. Lionfish have a voracious appetite for native fish, are armed with venomous spines, produce thousands of eggs every four days, and have no natural predators in their new range.
Why are species like the lionfish considered “invasive”?
a. They are found in areas where they are not native.
b. They were accidentally introduced by humans.
c. They spread aggressively and displace native species.
d. They are predators of other fish.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
