Marine Adaptations

How does viscosity become an obstacle to larger organisms? What do they have to overcome it?

Because the faster they swim the more viscosity impedes that swimming. They overcome it with their streamlined bodies.

What are some adaptations of deep-water nekton?

Bio-luminescence, large sensitive eyes and large sharp teeth

Provide example of mutualism symbiotic relationship

Both organisms benefit. Clown fish and anemone.

Which has a higher viscosity, warm or cold water?

Cold water.

What have some organisms developed to help them maintain their position?

Extensions

For a phytoplankton, which water temperature is easier to float in and maintain their position?

High viscosity because it allows them to maintain their position in sunlit areas of the ocean.

How do organisms overcome pressure of ocean water?

Many organisms lack inner air pockets.

Provide example of commensalism symbiotic relationship

One organism benefits, while the other is unharmed. Ex. barnacles and whales.

Describe daily vertical migration

Organisms migrate to deep waters during the day to hide from predators and rise during the night to feed on phytoplankton. Examples are copepods, lantern fish and krill.

Water is transparent. How do some organisms overcome transparent waters. Include examples.

Some organisms like the octopus simply camouflage with their surroundings. Sharks on the other hand countershade which means they're dark on top and light on the bottom.

What is symbiosis? What are the three different types?

Symbiosis is the relaitonshipo between two or more organisms where at least one benefits. The three types are commensalism, mutalism, and parasitism.

What is viscosity? How does it change in ocean water?

Viscosity is the substances resistance to flow. Viscosity of ocean water increases as salinity increases and temperature decreases.

What are the different adaptations that marine life have for living in the marine environment? Describe each adaptation

Viscosity, maintaining their position, daily vertical migrations, streamlined bodies, overcoming waters transparency, and pressure.

What is schooling?

When large numbers of fish, squid, or shrimp form well-defined social groupings.

What are photophores?

light producing organs
