Final answer:

The animal described is an osmoconformer because its internal osmotic pressure changes in line with the ambient osmotic pressure. Osmoconformers do not regulate their internal osmotic pressure actively unlike osmoregulators, which maintain steady internal conditions.

Step-by-step explanation:

If the ambient osmotic pressure increases, and an animal's blood osmotic pressure increases at the same rate, the animal can be classified as an osmoconformer. Osmoconformers match the osmotic pressure of their body fluids with that of the environment, meaning that when the ambient osmotic pressure changes, their internal osmotic pressure changes in concert without the animal exerting control over the process.

An example of an osmoregulator is a salmon because they need to remove excess salt from ocean water when they move from freshwater environments to the ocean. Mammals, including humans, also typically function as osmoregulators, maintaining homeostasis in terms of fluid and electrolyte balance across their body's fluid compartments.
