Osmoconformers versus Osmoregulators
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
An osmoconformer matches its internal solute concentration to its environment; an osmoregulator actively maintains an internal concentration different from its surroundings, regardless of external change.
Show
A marine invertebrate osmoconforms with seawater; a freshwater fish osmoregulates to stay saltier than the surrounding water.
Watch for
Osmoconforming is not the absence of regulation — a conformer can still regulate specific solutes while matching total concentration.
Builds on
- Nothing — this is a starting point.
