-This week, I watched Ron Underwood's Tremors (1990) starring Kevin Bacon and Fred Ward. A link to the IMDb page can be found here: http://www.imdb.com/title/tt0100814/?ref_=nv_sr_1

-This was an extremely ridiculous movie that exemplifies the late 80s and early 90s. "Graboids" attack the town and its up to 2 ridiculous Nevada cowboys to take care of these blind and tooth-filled creatures. This movie was comedic simply based on the ridiculousness of the movie. A cameo by Reba McEntire makes the whole film worth it in my opinion. My favorite scene is the ending when the graboid plummets to its death off the cliff. Tremors really captures old 50's monster movies. 5/10 stars.

-On to the science side of this film. These creatures known as graboids, is a fictional species of sand worm that is blind and lives underground. These creatures can move incredibly fast through the sand and use echolocation to  determine where it is. Not much thought was put into the name of these creatures because their tentacles "grab" its prey and bring it in. They have a reptilian appearance although they are worm and have tentacles. These creatures do not resemble any creature I have ever seen. Scientifically could they exist? I'm not too sure. They are said to weigh 10-20 tons. yet they are able to burrow faster than humans can run. Their diet consists of humans and cattle, and they would also need to eat quite a few calories to fuel their metabolism. But, they are unable to differentiate between the things they are eating, so they eat everything and then spit up whatever is not edible. This is not a very good evolutionary system. Tremors does not try to explain the creatures, but simply states that they are there. I was interested into how echolocation worked after watching this movie. It is an incredible process. I am however curious to how it would work while underground.
