Since the actual time (dT') is measured by the lecturer, the apparent length of time according to your mental reference frame (dT) dilates and becomes longer than the actual time. According to the relativity formula, dT = dT' / sqrt(1 - v^2/c^2).

However, one of Carl Thurman’s students (Abby Hutchins) recently wrote an undergraduate thesis describing all of the Atlantic fiddler crab species, including a color photo of each. In this thesis, she has the following photo for virens, describing it as “typical color of live M. virens”. 38/42

Introducing our new, ~3 months old, fur babies: Abby and Normal
Abby is very dark brown (not quite black) with very subtle striping and silver highlights here and there. Normal is a gray tabby.
We now return you to your regular life, already in progress.

Robert Sokal's lab used to record the height of lab members by marking them on the door frame. When he retired and the lab was going to be renovated, we recorded the data for posterity. The distributions of the heights, when categorized by the sex of the researcher, was amusing:
