Simon,

I think it's just more simple: Torsen gave us elements of hydrology theory (formal one;-) abstracted from bio-objects.

Suppose this theory can predict flood movement and other hydrology processes.

But where crocodiles? They are neglected. Abstraction.

They do not impact to hydrological processes of interest. Do they?

Ask hydrologists:-)

I think they have an amendment to the coefficient of viscosity of the water in this case;-)

Re the discussion about water/crocodiles/water bodies etc:

This issue is partly accommodated by the O&M model, where the 'feature-of-interest' (e.g. a specific water body) is distinguished from the 'observed-property' (concentration of crocodiles) (and also from the procedure or sensor).
This in turn is a corollary of the underlying 'feature model' which, like pretty much all of the meta-models we are using including OWL, distinguishes between classes/objects and properties/property-values.

There is an issue that many vocabularies of 'observed properties' conflate these concerns, so in standard water property vocabularies we see entries like:
   'concentration of crocodiles in a water body measured using a fooglemeter averaged over 3-day intervals and expressed as a number scaled by the unit-of-measure "bites"'.

But the analysis is established in O&M since many years now.
