This comic is about the frivolousness of many modern problems. While an offscreen character is panicking over deleting a file, the turtle is content with just being a turtle. The text saying "turtles have it figured out, man" indicates that Randall appreciates this simpler mode of thought.
Based on its appearance, it is possible that the turtle is a tortoise (biologists call all testudines turtles, and tortoises are the family of land-based turtles), which is also supported by the fact that tortoises tend to have much longer livespans (100 to 150 years) than sea turtles and terrapins (approximately 80 years).
An alternative explanation could be that the satisfaction of knowledge that the creature has poses an obstruction to his venturing out and finding its true identity. It was told that it's a turtle, thus, it continues to believe, even though it's wrong. The minor panicking of humans actually is a driving force of our sentience.
The title text is possibly a reference to 231: Cat Proximity . It also resembles Towelie's Catchphrase from South Park .
The text at the bottom 'Turtles have it figured out, man' could be a reference to the turtle in Finding Nemo , who speaks in a similar manner.
