This is a biological model of the interaction between baleen whales and their food source krill. It is similar to the Lotka-Volterra model in some respects, but has some very different features. The model equations are given below.

Here *x* represents the population of krill, and *y* the population of
baleen whales. The five parameters in the model must have positive
values.
