The ionic composition of the plasma and erythrocytes of deep sea fish
Abstract:
This paper reports measurements of the plasma osmolarities, the main inorganic ions and the concentrations of plasma proteins in nine species of deep sea fish from depths of 900-4,000 m. Chloride and magnesium values are high compared to those of shallow water fish. These ions may be contaminants from sea water either contributing to, or resulting from, the animals' moribund condition. They may also contribute to the failure of isolated erythrocytes to show ionic regulation even after being restored to their normal high pressure.

Structure and Function of Erythrocytes
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...
