The site at a glance looks like a credible source. It contains information such as habitats, anatomy, thought process, reasons for being endangered, how you can help, and other information. But, for one, this site contains no sources! Another reason it isn't credible is that it has no about the author page, or contact button. And, most importantly, an octopus skeletal structure would NOT allow it to swing throught trees!
Numerous studies have been carried out regarding students' abilities to classify a source as credible. One involing a group of 7th graders (Link ) stated that 24 out of the 25 school's best online readers recommended the website to another class and stated it as credible. Another (Link ) stated that not only did the students believe the fabricated information, but insisted that it was real even after the professor told them it was a fake.
