Marine Biology

Marine biology is the study of organisms that live in the ocean or any body of water. It deals with the relationship between ocean phenomena, and the adaptation and distribution of organisms.

Do fish have personalities?

Some research out of the University of Exeter suggests that fish do have personalities behind those blank stares. Tom Houslay and his research team exposed guppies to scary stuff—a fake heron (rather aptly named Grim) and a fake cichlid, a predator fish (they called him Big Al, which I appreciate more than I can put into words). The team recorded the guppies’ responses over several exposures to those scares, and not only did individual fish react differently to the fright, but they did so in the same ways time after time.

The researchers thus concluded that the fish have their own, limited sort of personalities—in spite of being raised in the exact same environment, they respond to stimuli in ways that vary from fish to fish.

How do sea urchin reproduce asexually?

The sea archin releses sperm and eggs in to the water the eggs then get firtilised

How do baby turtles find the water?

If you are talking about sea turtles, they just head out to the sea even though they never saw anyone do that besides themselves or their brothers and sisters. It is an inherited behavior. They just do it automatically. And pet and freshwater turtles just go inside. They get out of the place they were hatched, and then they go into the water to cool and wash themselves. This behavior is inherited.

Baby sea turtles use the presence of natural moonlight to find their way to the coast at night. This is why coastal light pollution is such a problem because it disorients the baby turtles.

Marine Biology

Does the music affect the respiration rate a fish?

Although I can not say authoritatively, I can however say that fish can not "hear" as we do but instead sense vibrations with their swim bladder. Some fish, particularly fresh water Amazonian fish, sense the vibrations from thunder storms which act as a signal to spawn. Bass frequencies in music can imitate this. One would assume that their respiration rate would increase as a result of the urge to spawn.

Why do organisms compete within ecosystems?

To get food and survive.

The difference between seaweeds and plants?

Seaweeds are not plants. They are protists. They differ from plants in that they lack vascular tissues (xylem and phloem), they have holdfasts instead of roots, and their cells do not have all of the plant characteristics.

When and why does phosphorescence occur in Puget Sound?

Phosphorescence occurs in places all over the world and it happens when small micro organisms " glow" in the water. These plankton like creatures come from the bottom of the ocean where it's dark so they only come out at night. I have seen phosphorescence in the puget sound before and it occurs around the middle of august in the summer but in the sound it only happens in summer. Most of the times I have noticed it's a clear night with no rain.

Do amphibians live in fresh water?

They are all freshwater- there are no saltwater amphibians.

Is a mushroom omnivore or herbivore?

Neither, it is a decomposer.

Marine Biology

What types of environments do crabs live in?

Crabs live in aquatic habitats ,specifically near sea shores .

Marine Biology

What term describes the movement of water molecules in and out of the cell?

The movement of water through a semipermeable membrane is called osmosis.

Marine Biology

What do krill eat?

AnswerKrill eat small animals called zooplankton. Zooplankton in turn eat phytoplankton, the 'grass of the sea', which are extremely small plants that are are nurtured by minerals that come up in cold water from the ocean floor toward the upper levels of water in the ocean.

Krill also eat algae, a green plant the grows on rocks or is located in water. But krill also eat plankton, until they get eaten by whales, penguins and seals.

Krill, those tiny crustaceans that are near the base of the marine food chain, are often found filtering out phytoplankton, specifically a type of tiny algae knows as diatoms. They will also eat almost anything else organic that they can grasp and devour.

They can eat zoo plankton which eats phytoplankton. Phyto plankton is a microscopic plant that zooplankton eat.
Krill eat phytoplankton which are small almost micro organisms sort of like tiny plants but more like cells since krill are so small that is all that they eat.

What kind of envirementn do cnidarias live in?

Cnidaria are also known as jellyfish and are strictly a marine species and have a global distribution ranging from hot tropical waters up to temperate and artic waters. Cnidarians can be either mobile (moving) or sessile where they remain fixed in one location.

Cardiovascular Health
Marine Biology

What is the main function of the arteries?

Most arteries carry oxygenated (oxygen-rich) blood from the heart to the rest of the body. Most veins carry deoxygenated (containing less oxygen and more carbon dioxide and other wastes) blood from the body tissues to the heart, which then sends that blood through the pulmonary system to be oxygenated again. The only exception to this is the pulmonary system. The pulmonary veins carry oxygen-rich blood back to the heart and the pulmonary arteries carry deoxygenated blood from the heart to the lungs.

An ocean animal with five eyes one on each arm and has hundraads of tube feet?

I think it's a starfish
Its a Star-fish

Actually for the kids homework, It was a "Seastar" :)

Oceans and Seas
Marine Biology

Why do most marine organisms live near the ocean?

Marine organisms have to live in ocean because that is the only way they would be able to survive. Marine= found in, or produced by the sea. So marine organisms live in the sea,oceans,etc.

Marine Biology

Is cryptic coloration of frogs an example of mutualism?

I thought it was because it helps both the predator and the prey survive longer in their habitat, but I just had a multiple choice biology test where it asked for an example of Mutualism, and I chose cryptic coloration, but he was looking for another choice which was coral and algae. So I guess not?

Marine Biology

How do you think tiny krill provide enough food to sustain whales?

The reason they can provide enough food is because whales eat so many of them (10-15 tons).

Endangered, Vulnerable, and Threatened Species

What coral is becoming extinct?

There are many corals threatened with with extinction. Current estimates are that for a variety of reasons, pollution, fishing, disease, warming oceans fully one half of all corals are threated. Some examples are The Great Barrier Reef off Australia; the reefs of Hawaii in Kaneoke Bay and Waikiki Bay; reefs off Guam, the Virgin Islands, Jamaica, and Bermuda; and reefs in the Indian Ocean: all are in various stages of destruction. African states with endangered reefs in the western Indian Ocean include Kenya, Tanzania, Mozambique, Mauritius and the Seychelles. Florida's barrier reef was calculated in 1986 to be dying at the rate of 4% a year. In 1991, parts of the reef were dying at the rate of 10% a year. Reefs consist of many types of coral such as Brain, Staghorn, Pillar, Black, Whip, Fan etc.
