Maybe it’s a certain mass of meat? I also don’t see any reason the food chunk needs to be an integer number of whatever unit it’s measured in.

- valarauko 5y agoSomething like 10g of meat would make sense in this context too. The fact that the article specifies that the strips are measured out in length suggests weight isn't the criteria. It doesn't have to be an integer value (or a reasonable in-between value like 1.5 or 2.5) of whatever unit they used, but its the most parsimonious approach for the graduate student who actually does the work - unless there is a good reason not to. EDIT: from the paper:- > Individuals were offered squid pieces that were 3 mm by 30 mm. These prey dimensions were ideal for this study because they were small enough that feeding on a single prey item would not result in satiation, which could influence feeding kinematics (Sass and Motta, 2002). Also, offering prey of a rectangular shape rather than a square shape provided length that elicited head movements, which enabled us to observe multiple protraction and retraction cycles during transport.
