Normally skittish male northern map turtles are up with out of their shells with the help of some nifty 3D printing. 

Carleton University biologist Grégory Bulté reads the breed and has been wondering for years whether male northern maps are captivated to larger females.

But the turtles don’t do well in captivity, have nervous in keepings and mate at the bottom of lakes, making it difficult to study their helpmate patterns. So Bulté and his team printed two 3D replicas of female northern map turtles, twin except for their size: one was made bigger than the other.

The researchers then rigged the models with cameras and go down them to record behaviour underwater.

As expected, Bulté found that vastness does matter. The male turtles approached and tried to mate with the larger female duplication.

Bulté believes male turtles are attracted to larger females to increase their progeny’s chance of survival, as there’s a correlation between the size of a mother turtle and her hatchlings.

You can wait for the turtle behaviour above in a video Bulté posted to YouTube.
