What is the difference between Epifauna and infauna?
There are two groups of benthic organisms, based on their habitat: epifauna and infauna. Epifauna live attached to a surface and infauna live within bottom sediments.
What is Epifaunal?
Definition of epifauna
: benthic fauna living on the substrate (such as a hard sea floor) or on other organisms — compare infauna.
What are examples of infauna?
Infauna definition
Clams, tubeworms, and burrowing crabs are infaunal animals. Aquatic animals, such as clams or burrowing worms, that live beneath the surface of a sea or lake floor. The animals burrowing into marine or freshwater sediment. An aquatic organism that lives within the dominant medium of its environment.

What are epifauna Epiflora and infauna?
Epiflora or epifauna live on the sea bottom. Infauna live in the sea bottom. Benthic plants are restricted to shallow waters because of their requirement for light. Benthic animals occur everywhere from shallow depths to the deep sea.
What would you describe as the differences between infaunal semi infaunal and epifaunal habitats?
Infaunal: Animals that live in the bottom within the sediment such as clams. Epifaunal: Animals that live on or attached to the surface of the bottom, e.g. oysters and barnacles. Semi-infaunal: Those animals that are partially burrow in the bottom e.g Artina.
What is Epibenthic?
“Epibenthic” refers to organisms that live on or just above the bottom sediments in a body of water. These organisms, many of which support commercial and recreational fisheries, tend to forage on the creatures that live in or on the sediments.
Is Coral an Epifauna?
Attached epifauna comprise a wide range of taxa from hydroids to cirripedes. Included among free-living epifauna are some echinoderms, decapods, and bivalves.
…
Epifauna.
| Life form | Examples |
|---|---|
| Attached epifauna | Cnidaria: Hydrozoa – hydroids |
| Cnidaria: Anthozoa – gorgonian corals | |
| Cnidaria: Antipatharia – octocorals | |
| Bryozoa – bryozoans |
What does the word infauna mean?
Definition of infauna
: benthic fauna living in the substrate and especially in a soft sea bottom — compare epifauna.
Where is infauna found?
Infaunal Benthic Invertebrate Organisms
“Infaunal” refers to aquatic animals that live in the substrate of a body of water and which are especially common in soft sediments. “Benthic” refers to anything occurring at or in the bottom of a body of water. “Infauna” are the creatures tht live in the sediments.
Are crabs infauna or epifauna?
Many types of crustaceans live in epifaunal communities on the floor of bodies of water such as oceans or fresh-water lakes. These include crabs, lobsters, crayfish (or crawdads), copepods, barnacles, cumaceans (a type of crustacean), and ostracods.
What does the sessile epifauna consist of?
Virtually, all sessile epifauna are filter feeders, relying on currents to carry their food to them. There is a variety of sessile solitary invertebrates that attaches to hard substrates, typically bedrock. These include barnacles, oysters, some brachiopods, and mussels; sponges, sea anemones, and sea-lilies.
Are corals epifauna or infauna?
Epifauna
| Life form | Examples |
|---|---|
| Attached epifauna | Cnidaria: Hydrozoa – hydroids |
| Cnidaria: Anthozoa – gorgonian corals | |
| Cnidaria: Antipatharia – octocorals | |
| Bryozoa – bryozoans |
What is a benthic habitat?
Benthic habitat maps help protect fragile underwater areas.
The term benthic refers to anything associated with or occurring on the bottom of a body of water. The animals and plants that live on or in the bottom are known as the benthos. In ocean waters, nearshore and estuary areas are most frequently mapped.
Which of the following organisms are considered as benthic organisms?
Benthic organisms, such as sea stars, oysters, clams, sea cucumbers, brittle stars and sea anemones, play an important role as a food source for fish, such as the California sheephead, and humans.
Is a sea cucumber Epifauna?
Sea cucumbers are a common epifaunal animal found on soft bottoms. Many sea cucumbers are deposit feeders – taking in the soft sediments, digesting the organic material and infauna in the sediment and leaving behind cleaned sediment.
Are crabs Epifauna?
Where is Infauna found?
What is Infaunal in biology?
7.04. 3.9 Infauna. Infauna are invertebrates living within the matrix of aquatic sediments and include polychaetes, oligochaetes, bivalves, nemerteans, echiurans, sipunculids, as well as small crustaceans such as burrowing amphipods and isopods.
Are corals Epifaunal?
Are sea urchins Infauna?
This group includes various meiofauna and macrofauna such as snails, clams, worms, sea urchins, and crustaceans. Some groups are entirely infaunal, such as the tusk shells (scaphopods).
Is a sea cucumber epifauna?
What are the 5 zones of the benthic environment?
Introduction to marine biology
The benthic zone is subdivided into different zones, namely intertidal or littoral zone, supralittoral zone, sublittoral zone, bathyal zone, abyssal zone and hadal zone.
Why are benthic important?
Many benthic species convert live plant and dead organic material into prey items for larger consumers in complex food webs. In the process of maintaining energy flow, these benthic species simultaneously provide essential ecosystem services, such as nutrient cycling and aeration of sediments.
What are the 4 main groups of benthic animal?
feeders, Herbivores, Carnivores and Scavengers.
