Marine mammals and sonar concern, but very little definitive information was known. In 1995 a comprehensive book on the relation between marine mammals and noise had been published, and it did not even mention strandings. In 2013, research showed beaked whales were highly sensitive to mid-frequency active sonar. Blue whales have also been shown to flee from the source of mid-frequency sonar, while naval use of mid- and high- frequency side-scan sonar was deemed 'the most probable cause' of a mass stranding of around 50 short-beaked common dolphin ("Delphinus delphis") on 9 June 2008 in Falmouth Bay, Cornwall, UK. There was anecdotal evidence from
Creature Features periodically, but never with great success. It was re-broadcast in 1979–1980, but cut due to poor ratings again. "Creature Double Features" was the name of a show broadcast by WKBG Channel 56 in the Greater Boston area. In 1972 WKBG, a station in the Kaiser Broadcasting chain, aired its collection of "Godzilla" movies on Saturday under the title, "The 4 O'Clock Movie". Shortly thereafter, they started calling it "Creature Feature" and then "Creature Double Feature". The show quickly became a staple of the station's Saturday programming schedule during the 1970s and early 1980s. The final show was sometime in 1983.
