What is the difference between infauna and epifauna?
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.

The animals burrowing into marine or freshwater sediment. An aquatic organism that lives within the dominant medium of its environment.
What is epifaunal?

Where are 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.

: benthic fauna living in the substrate and especially in a soft sea bottom — compare epifauna.
Are sea cucumbers 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 sea urchins epifaunal?
Echinopsis is an extinct genus of sea urchins in the class Echinoidea. These slow-moving low-level epifaunal grazers lived from the Cretaceous to the Paleogene periods (125.45 – 5.332 Ma).
