Unlike Other Vertebrates,the Body Fluids of Hagfishes Are

Question

Unlike other vertebrates,the body fluids of hagfishes are
A)strongly hypoosmotic to seawater.
B)strongly hyperosmotic to seawater.
C)in osmotic equilibrium with seawater.
D)very concentrated,with over 80% blood solids.
E)under high internal pressure near the surface.

Accepted Answer

Hagfishes, unlike other vertebrates, have body fluids that are in osmotic equilibrium with seawater, meaning their internal fluid concentration matches that of the surrounding sea, avoiding the need for active osmoregulation to maintain fluid balance.
