Difference Between Benthic and Pelagic

The first major distinction is between the pelagic and benthic zones. The pelagic zone refers to the water column, where swimming and floating organisms live. The benthic zone refers to the bottom, and organisms living on and in the bottom are known as the benthos.

What is the pelagic zone of the ocean?

The pelagic zone refers to open and free waters in the body of the ocean that stretch between the ocean surface and the ocean bottom and are not too close to some boundary, like a shore or the seafloor or the surface.

Which is the benthic zone?

The benthic zone is the lowest ecological zone in a water body, and usually involves the sediments at the seafloor. These sediments play an important role in providing nutrients for the organisms that live in the benthic zone.

Where is the benthic?

The benthic zone is the ecological region at the lowest level of a body of water. It starts at the shoreline and continues down until it reaches the floor, encompassing the sediment surface and sub- surface layers.

What is biota of the pelagic?

Organisms that live in the benthic region are coined as 'benthos', and organisms found in the pelagic zones are referred as pelagic organisms. ... However, there is a gradient of these in the pelagic zone from top to bottom.

What are the 3 zones of the ocean?

There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone.

Do sharks live in the pelagic zone?

Pelagic or oceanic sharks live in the open waters of seas and oceans. They inhabit tropical and temperate waters, and many are migratory. ... However, there are also three species of large plankton eating filter feeders – the whale shark, the basking shark and the megamouth shark.

How deep is the benthic zone?

The benthic zone starts at the shore and extends down along the bottom of the lake or ocean. This means that it could be as shallow as a few inches at its start, but may reach depths of 6,000 meters as it coincides with the abyssal plain at the bottom of the ocean.

Why are benthic macroinvertebrates important?

Why is it important to evaluate benthic macroinvertebrates? Benthic macroinvertebrates are commonly used as indicators of the biological condition of waterbodies. They are reliable indicators because they spend all or most of their lives in water, are easy to collect and differ in their tolerance to pollution.

How deep is the abyssal zone?

The Abyssopelagic Zone (or abyssal zone) extends from 13,100 feet (4,000 meters) to 19,700 feet (6,000 meters). It is the pitch-black bottom layer of the ocean. The name (abyss) comes from a Greek word meaning "no bottom" because they thought the ocean was bottomless.

Is jellyfish a Benthos?

Jellyfish are usually thought of as drifting organism there are in fact some forms of medusae and ctenophores that are benthic, with the adult sexual stage spending their entire life on the seafloor.

Are crabs benthic?

Adult crabs are primarily benthic creatures and live on the bottom of the Bay.

Are sharks benthic?

Describing organisms that inhabit the region of a body of water that includes the bottom of a lake, sea, ocean, river, etc. An example of benthic sharks would be the Houndsharks, including the leopard shark (Family Triakidae).
