Is Science represented correctly???

Choose one of these cartoons and evaluate how science is represented and argue if its correct or how it should be corrected.

What would be some possible hypotheses these two gentlemen could create from these observations?

Killer Crustacean in British Isles

Researchers have a new fear of a crustacean nicknamed "killer shrimp" invading the British Isles making light work of various native species in the waters by shredding them without eating them.

This crustacean is from western Asia and has made its way to the ocean waters of the British Isles, possibly through human influence (i.e. possible transport from fisherman). More specifically, this crustacean's home is in the Black and Caspian Seas and in the last twenty years has made its way over to central and western Europe through various waterways like the Danube and the Rhine.

Barely bigger than an inch long, this amphipod has violent and vicious killing behavior using powerful mouthparts to literally shred its prey. In addition, their killer, aggressive behavior only increases when the number of prey increases.

This predator is well adapted by having the ability to reach maturity quickly, reproduces all year round, lays 200 eggs at a time, has a wide range of food, and can survive all kinds of ocean chemistry changes in temperature, salt and oxygen. Even more impressive is the ability to survive out of water for six days!

In some places, the population size has reached as many as 4, 000 in one square meter of ocean water. The biggest concern among scientists include how to control this predator from reducing the populations of other invertebrates and fish in valuable fisheries.

What are some possible solutions to either eliminate or control the spread of this killer species? Be specific!
