Which are the most common animals of the sea?

What's the biggest creature in the sea?

The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.

What is the biggest thing in the sea?

The blue whale (Balaenoptera musculus) is undoubtedly the biggest creature in the sea, and is in fact the largest animal to have ever lived on plant earth – a fully-grown blue whale is double the size of the largest land-dwelling dinosaur that ever lived.

What is a sea animal?

A sea animal is any type of animal that lives in a body of saltwater (like a sea or ocean), so starfish and krill are just as much sea animals as a whale is. All sea or ocean-dwelling animals can be further classified based on how they move and where they live.

Are there monsters in the ocean?

Hundreds of years ago, European sailors told of a sea monster called the kraken that could toss ships into the air with its many long arms. Today we know sea monsters aren't real--but a living sea animal, the giant squid, has 10 arms and can grow longer than a school bus.

What is the smallest sea creature?

Zooplankton. Zooplankton may very well be the smallest type of animal in the ocean and encompass a variety of species, from single-celled protozoa to some jellyfish and crustaceans like krill.

What is the deepest sea creature ever found?

Of the cephalopods, Dumbo octopuses (Grimpoteuthis) are currently thought to be among the deepest-dwelling. Species have been discovered between 400m and 4,800m below the surface of the waves inviting further study into how these rarely glimpsed gelatinous creatures live in such varying depths.

How many teeth does a seahorse have?

Seahorses have no teeth and no stomach. Food passes through their digestive systems so quickly, they must eat almost constantly to stay alive. They can consume 3,000 or more brine shrimp per day.

What is the largest creature to ever live?

Far bigger than any dinosaur, the blue whale is the largest known animal to have ever lived. An adult blue whale can grow to a massive 30m long and weigh more than 180,000kg - that's about the same as 40 elephants, 30 Tyrannosaurus Rex or 2,670 average-sized men.

What are in the ocean?

The oceans hold about 321 million cubic miles (1.34 billion cubic kilometers) of water, which is roughly 97 percent of Earth's water supply. Seawater's weight is about 3.5 percent dissolved salt; oceans are also rich in chlorine, magnesium, and calcium.

Why is the ocean blue?

The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.

Why is the ocean salty?

Ocean salt primarily comes from rocks on land and openings in the seafloor. ... Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.

What is the craziest fact about the ocean?

Thanks to the ocean, most of our planet is dark.

Oceans have an average depth of 12,100 feet, and because light waves can only penetrate 330 feet of water, everything below that point is dark. Seeing as water makes up most of the planet, this means that most of Earth exists in absolute darkness all the time.
