What are the 3 groups of marine life?
Three main groups of ocean life are plankton, nekton, and benthos. Plankton float in the water. Nekton swim through the water. Benthos live on the ocean floor.
What is marine life classified by?
Linnaean Taxonomic System
How many marine organisms are there?
According to the World Register of Marine Species, WoRMS, the total number of marine species known to us is about 240,000 species (2021 census). However, it is estimated that there are 1.4 -1.6 million marine species on earth (Bouchet, 2006.).
What are the main divisions of the marine environment?
We can correspondingly make two major divisions of the environment, the Pelagic and the Benthic, the Pelagic Division comprising the whole body of water forming the seas and oceans, and the Benthic Division the entire sea bottom (Figure 1.8).
Under which category would corals fall into?
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps.
What different groups of animals are called?

- Apes: a shrewdness.
- Badgers: a cete.
- Bats: a colony, cloud or camp.
- Bears: a sloth or sleuth.

What are the three groups of marine animals?
Marine animals are divided into three groups: zooplankton (those that float), nekton (those that actively swim) and benthos (those that live on or in the ocean bottom). Marine animals are divided into three groups: zooplankton, nekton, and benthos.
How are marine organisms related to each other?
Classification is an important tool used by scientists to show how organisms are related to each other and to group them by their characteristics, but this can be difficult for some marine organisms! Classification involves grouping organisms into a series of hierarchical categories: kingdom, phylum, class, order, family, genus and species.
Why is it important to classify marine organisms?
Classification is an important tool used by scientists to show how organisms are related to each other and to group them by their characteristics, but this can be difficult for some marine organisms! In the 18th century, Carl Linnaeus published a system for classifying living things.
Which is the largest group of animals in the ocean?
The zooplankton population also includes some temporary members such as fish eggs or larval forms of organisms which may grow up and leave the planktonic community to join the nekton or benthos. Nekton are the free swimmers and probably the largest portion of familiar animals found in the ocean belong to this class.
