Marine fish are hyposmotic to seawater. Their body fluids have a lower salt concentration. They lose water through osmosis via their gills. To stay hydrated, they must drink seawater. They excrete excess salts using specialized cells in the gills. This process helps them maintain electrolyte balance and water balance. Marine fish drink large amounts of … Read more

Marine fish are hypoionic because their body fluid concentration has lower electrolytes than the surrounding seawater. This difference causes water to flow out through osmosis. To maintain fluid balance, marine fish absorb seawater and actively excrete excess salts, adjusting to their high-salinity environment. Marine fish actively minimize salt intake. They have specialized cells in their … Read more

Marine fish are hyposmotic to seawater. Their blood has fewer solutes than seawater, causing water loss through gills. To counteract this, they drink seawater and remove excess salts. This osmoregulation helps them maintain essential electrolytes in a high-salinity environment. Marine fish drink large amounts of seawater to replenish lost water. Their gills actively excrete excess … Read more

Marine fish are hypoionic. Their blood has a lower ionic concentration than seawater. This difference causes water to move out of their bodies through osmosis. To balance fluid loss, marine fish drink seawater and excrete dilute urine. This process helps maintain their water intake and electrolyte balance in the salty environment. To achieve this, these … Read more

Marine ecosystems are essential for fish. They offer habitats and food sources, supporting biodiversity. Fish play a vital role in nutrient cycling, which helps maintain healthy marine environments. These ecosystems support food webs, ensuring the survival of various species, including humans who depend on fish for nutrition. Healthy marine ecosystems serve as breeding grounds and … Read more

Marine fish and mammals have different digestive systems due to their dietary needs. Marine mammals have a mouth, esophagus, stomach, and intestines. This helps them absorb nutrients from varied prey and plant foods. Marine fish, however, lack stomach acids and salivary glands, using seawater to digest macronutrients in their simpler system. In contrast, marine mammals … Read more

Cartilaginous fishes, known as Chondrichthyes, excel at reproduction due to internal fertilization. They produce fewer, larger eggs rich in yolk, leading to higher survival rates for their young. Their flexible skeleton aids movement, while advanced development stages improve energy efficiency during reproduction. One notable strategy is internal fertilization. Male cartilaginous fish use claspers, elongated fin … Read more
