Although abundance of the key functional species, the common piddock Pholas dactylus , and the tube worm Polydora ciliata may be high, other fauna are relatively sparse so competition for space is not likely to be a factor structuring the biotope. (marlin.ac.uk)
There are few species that prey on other members of the community although feeding by fish and predatory crabs probably occurs. (marlin.ac.uk)
Crabs, such as Pisidia longicornis are the predominant mobile species in the biotope, travelling through as they scavenge for food. (marlin.ac.uk)
Some of the characterizing species in the biotope, such as piddocks, the sponge Halichondria panicea and the anemone Urticina felina have a longevity of several years and may not show great seasonal changes. (marlin.ac.uk)
A similar biotope IMU.Tub can be separated from IMU.CapTub by a swap in the dominant species from Capitella capitata to Tubificoides spp. (marlin.ac.uk)
More mobile muds which occur in areas with an extremely high suspended particulate component to the water column, IMU.MobMud, may contain a similar suite of species to IMU.CapTub although in lower abundance. (marlin.ac.uk)
The biotope description and characterizing species are taken from JNCC (2015). (marlin.ac.uk)
Balanus crenatus distinguishes the biotope from other biotopes within the CR.HCR.FaT biotope complex that are domiated by cushion sponges or Alcyonium digitatum , and is therefore considered a key characterizing species. (marlin.ac.uk)
Other species typically present in the biotope include sponges, hydroids and the anemones Cylista elegans , Urticina felina and Metridium senile . (marlin.ac.uk)
Tubularia indivisa is a short lived species, and recruitment is seasonally variable with settlement peaking in early spring (march) however other smaller recruitment events occur within summer and autumn (Hughes, 1983). (marlin.ac.uk)
The key species defining this biotope is Branchiostoma lanceolatum, the biotope often contains communities of robust venerid bivalves (SCS.MedLumVen) and may include Echinocyamus pusillus , Glycera lapidum , Polygordius, Pisione remota and Arcopagia crassa (in the south of UK). (marlin.ac.uk)
As Branchiostoma lanceolatum is a key species distinguishing this biotope from other coarse gravel biotopes, the sensitivity assessments are largely based on this species as its loss would lead to biotope reclassification. (marlin.ac.uk)
Among the groups occurring in South America, one with the highest number of species is Rhipidodontini (Hyriidae, Unionida, Paleoheterodonta, Bivalvia). (scielo.br)
Several lineages colonized freshwater ecosystems, especially the order Unionida (Paleoheterodonta), as well as some species of Arcida, Mytilida (Pteriomorpha), Venerida, Myida, and Anomalodesmata (Heterodonta), suggesting that bivalve invasions of freshwater environments occurred numerous times ( Haag 2012 HAAG, W.R. 2012.

The Palaearctic butterfly genus Pseudophilotes Beuret, 1958 (Lycaenidae: Polyommatinae), that today occurs in North Africa and in Eurasia, includes ten described species with various distribution ranges, including endemics such as the Sardinian P. barbagiae . (biomedcentral.com)
The split between the lineage comprising bavius and fatma (sometimes treated as a distinct genus, Rubrapterus ) with Salvia species as larval host plants, and the remaining Pseudophilotes that utilize Thymus and other Lamiaceae (but not Salvia ), dates back to about 4.9 million years ago (Mya).

Habitat2
On occasion relatively large numbers of Capitella capitata can be found in sandier sediments within a more mobile habitat although these are thought largely to be imported by tidal streams from nearby populations (a definition of a separate biotope may be appropriate). (marlin.ac.uk)
Males patrol at suitable places (e.g. sunny knolls) in the larval habitat. (pyrgus.de)
Circalittoral3
This biotope occurs on circalittoral soft rock, such as soft chalk or clay, most often in moderately exposed tide-swept conditions. (marlin.ac.uk)
This biotope typically occurs on upward-facing, extremely tide-swept, circalittoral bedrock, boulders and cobbles found in a broad spectrum of wave exposures. (marlin.ac.uk)
Variants to this biotope may occur in deeper, circalittoral waters, with slightly muddy or gravelly sediments. (marlin.ac.uk)
Larvae1
Because lanceolatum releases excess sarmentosin as a defense against larval feeding, larvae are forced to wander to more nutritional plants after 1⁄2-1 hours, as high levels of sarmentosin can reduce larval growth rates (Doyle, 2017). (inaturalist.org)
Abundance2
The abundance of filter feeding organisms such as sponges, bryozoans and tunicates within the biotope indicates the importance of planktonic input to the benthic community. (marlin.ac.uk)
Macoma balthica , Arenicola marina and Eteone longa occur in the biotope at low abundance or frequencies and are not considered characterizing. (marlin.ac.uk)
Muddier2
The biotope is found in the muddier sediments, usually with a high organic content, away from tidal channels in estuaries. (marlin.ac.uk)
These transitional forms of the biotope to muddier, or more gravelly sediments may be characterised by polychaetes such as Notomastus latericeus , and the amphipod Urothoe marina . (marlin.ac.uk)
