What do saltwater fish eat? 

Saltwater fish can carry carnivore, herbivore, or omnivore diets. Herbivore saltwater fish consume both microalgae and macroalgae as well as seagrasses. A carnivore’s diet typically consists of shrimp, plankton, and tiny crustaceans. Some carnivores may eat worms, clams, and parasites. Most carnivore saltwater fish will not eat algae even if they are starving.

Why can’t saltwater fish live in freshwater?

Saltwater fish are not able to live in freshwater because their bodies are concentrated from salt solution. Saltwater fish would not be able to osmoregulate correctly in freshwater. Freshwater would flow into their body up to the point where all cells can accumulate water causing them to bloat and die.

How do you acclimate saltwater fish?

Saltwater fish can be acclimated in a couple of ways. This can be done by modifying the water’s salinity, altering the pH of the water, and using the drip method or the floating method. It is important to acclimate saltwater fish because changes in salinity, water temperature, and water chemistry can cause stresses that shock the fish to death.

How are cartilaginous fish different from bony fish?

Cartilaginous fish are different from bony fish through their skeletons that are made of mostly cartilage as opposed to bony fish which have skeletons composed mostly of bone. Both cartilaginous and bony fish fall under different types of taxonomic groups. Cartilaginous fish are part of the Chondrichthyes while bony fish are of the Osteichthyes class.

How do cartilaginous fish maintain buoyancy?

Cartilaginous fish maintain their buoyancy through their liver which is filled with oil. The oil within their liver helps cartilaginous fish lighten their body to keep it from sinking downwards into the body of water, while also helping the fish save energy to keep moving and direct themselves.

Do cartilaginous fish have jaws?

Cartilaginous fish have movable jaws that are equipped with fully developed teeth. The mouth of cartilaginous fish is typically located under their head. Cartilaginous fish only have one set of oral jaws that are made of cartilage. The jaws of cartilaginous fish are articulated and opposed vertically.

What do marine animals need to survive?

Factors that marine animals need to survive include bioluminescence which is when animals make their own light and helps them communicate and scare predators. Constant light, pressure, temperature, and food are factors needed to remain stable and help marine animals evolve to survive. Marine animals that live within the deep sea can withstand the cold.

Why do we need to protect marine life?

Humans need to protect marine life because our actions and lifestyles have a direct impact on the ocean. We need to protect marine life and provide a safe and healthy environment that is not impacted by overfishing, climate change, pollution, habitat destruction, invasive species, and other forms of human exploitation.
