 Bigfin reef squids adapt to warmer temperatures by laying more eggs , making them a good indicator species for climate change . In conjunction with their rapid growth rates and short lifespans , bigfin reef squid populations may rise dramatically in response to global warming . Overfishing may also play an important role . In the Gulf of Thailand , the fishing industry has been forced to adapt to the large numbers of bigfin reef squids now present in the area , believed to be the result of overfishing of the squid 's natural predators . The Australian scientist George Jackson describes them as " the weeds of the sea . "
