Summary

Description

The sunset cup coral is a bright yellow or orange stony coral. It has a tentacular polyp that emerges from a porous, calcareous skeleton. The skeleton may be short and cylindrical or tall and inversely conical. It is typically solitary but is rarely found in small groups forming 'pseudocolonies'. The tentacles are quite long and number around 96. When fully retracted the tentacles are barely visible inside the skeleton.

Recorded distribution in Britain and Ireland

Portland Bill, Lyme Bay, off Plymouth Sound, the Isles of Scilly and Lundy only. Believed to no longer occur in North Devon near Ilfracombe where it was present in 1969 (K. Hiscock, pers. comm.)

Global distribution

Found throughout the Mediterranean west of Cyprus and in the Adriatic. Also on the Atlantic coasts of SW England, the Channel Isles, Brittany and Portugal. It has not been recorded despite targeted survey in Madeira, the Azores, or the Canary Isles.

Habitat

Leptopsammia pruvoti prefers shaded bedrock or stable boulders and is typically found in caves and gullies or under overhangs. Found at open coast locations mainly facing away from prevailing winds. It is commonest between 10 and 30 m with a maximum depth of 40 m recorded in the western Mediterranean.

Depth range

10-40

Identifying features

  • Almost always solitary but sometimes found as small groups of corallia arising from one base (pseudocolonies).
  • The disk and tentacles are usually yellow, sometimes with an orange disk.
  • The polyp sits in a porous calcified skeleton.
  • Possesses about 96 tentacles.
  • Attached to bedrock or stable boulders in crevices, caves or overhangs.
  • The corallum may be from short and cylindrical to tall and inversely conical, height to 60 mm, diameter of the calyx to 17 mm.

Additional information

The synonym Leptopsammia microcardia was last used by Abel (1959) and Rutzler, 1966 despite the general recognition of their synonymy since 1954.

Biology information

Younger individuals have a round calice which becomes elliptical with age. The skeleton is porous. It is not known whether the species is hermaphroditic or gonochoristic. The size range applies to maximum height of the corallum. The longest diameter of the calyx is 17 mm. The growth rate has been observed to be very slow in aquarium specimens which are little fed and in the same seawater for several months (2 mm across calice after 18 months) but can be fast if fed and in continuous seawater supply (to 10 mm across calice after one year. (Paul Tranter, pers. comm.). Typically found as solitary individuals but may occur as several corallia from the same base forming 'pseudocolonies': during culture experiments, if any of the tissue overlying the skeletal column was lost, there would eventually appear, over a matter of weeks, one or more small polyps which would eventually form part of the 'parent' skeleton and give the impression of a naturally formed colony (Paul Tranter, pers. comm.). Leptopsammia pruvoti is known to have the ability to control and possibly 'farm' the bacterial content of its coelenteric cavity (Herndl & Velimirov, 1985). These bacteria could be used as an additional food source. The horseshoe worm Phoronis hippocrepia and the fan worm Potamilla reniformis bore into the base of the skeleton of Leptopsammia pruvoti and the bivalve Hiatella arctica further enlarges these boreholes. Once bored, the skeleton is weakened and corals may be easily detached.

Life history information

Lifespan has not been established for this species but it is probably quite long lived. Individuals tend to die through weakening of the skeleton by boring organisms and subsequent detachment by agents such as foraging fish or careless divers. However, skeletons (dead individuals) have been found still attached to rocks (K. Hiscock, pers. comm.) Populations tend to become extinct through lack of recruitment. Lacaze-Duthiers, (1897) suggests that the sexes are separate. Eggs are laid in succession , at indefinite, fairly well-spaced intervals over a period of time that must be substantial (Lacaze-Duthiers, 1897). Larvae have been successfully produced in aquaria. The eggs are released from the female stomach cavity and those that are unfertilised may float to the surface. Fertilised eggs (young larvae) swim actively in the water column (K. Hiscock pers. comm..) but settle rapidly to the substratum close to the adult, where after a period of freedom they attach themselves in the shape of an ovoid or a ciliated worm (Lacaze-Duthiers, 1897). The larval settling time is generally short but observations from aquaria suggest that the larval stage may exist for up to six weeks before settling. Recruitment is very sporadic. Over 12 years of monitoring on Lundy has shown little or no recruitment and the population there declined by 22 percent between 1993 and 1997. Recruitment may fail for several reasons. Environmental conditions (primarily temperature) are unsuitable for gamete production to occur or to occur synchronously. Alternatively larvae may be swept away into unsuitable habitat by water currents or be consumed by predators before metamorphosing. Recruitment in the Mediterranean is also sporadic. Some recruitment may occur through influx of southern water bodies bringing with it larvae.

Substratum loss [Show more]

Substratum loss

Benchmark. All of the substratum occupied by the species or biotope under consideration is removed. A single event is assumed for sensitivity assessment. Once the activity or event has stopped (or between regular events) suitable substratum remains or is deposited. Species or community recovery assumes that the substratum within the habitat preferences of the original species or community is present. Further details

Evidence

This species is permanently attached to the substratum so substratum loss would cause death. Gamete production, synchronous gamete production or successful recruitment are very unpredictable and sporadic primarily due to unfavourable environmental conditions. Local recruitment has not been recorded at Lundy during more than 12 years of monitoring but occurred to a small extent in 1998. Local recruitment is most likely but may also be from distant water bodies perhaps every 25-30 years. There has been no observation of colonization of wrecks or new natural surfaces near to existing colonies such as the breakwater at Plymouth Sound constructed in the early 1800's. Recovery will take a very long time or may not occur at all.

Smothering

Benchmark. All of the population of a species or an area of a biotope is smothered by sediment to a depth of 5 cm above the substratum for one month. Impermeable materials, such as concrete, oil, or tar, are likely to have a greater effect. Further details.

Increase in suspended sediment

Benchmark. An arbitrary short-term, acute change in background suspended sediment concentration e.g., a change of 100 mg/l for one month. The resultant light attenuation effects are addressed under turbidity, and the effects of rapid settling out of suspended sediment are addressed under smothering. Further details

Evidence

This species is permanently attached to the substratum and would be unable to avoid changes in siltation. However, the species tends to inhabit caves or overhangs which are less likely to be exposed to suspended material settling out. The polyp will most likely 'inflate' with water to expand above the silt if briefly covered. Increased siltation may clog feeding apparatus and there would be an energetic cost to clearing this sediment. Gamete production, synchronous gamete production or successful recruitment are very unpredictable and sporadic primarily due to unfavourable environmental conditions.

Desiccation [Show more]

Desiccation

  1. A normally subtidal, demersal or pelagic species including intertidal migratory or under-boulder species is continuously exposed to air and sunshine for one hour.
  2. A normally intertidal species or community is exposed to a change in desiccation equivalent to a change in position of one vertical biological zone on the shore, e.g., from upper eulittoral to the mid eulittoral or from sublittoral fringe to lower eulittoral for a period of one year. Further details.

Evidence

The species is only found subtidally (typically 10-30 m) and the polyp is soft bodied. Exposure to desiccating influences would cause death. Gamete production, synchronous gamete production or successful recruitment are very unpredictable and sporadic primarily due to unfavourable environmental conditions. Local recruitment has not been recorded at Lundy during more than 12 years of monitoring but occurred to a small extent in 1998.

Increase in water flow rate

A change of two categories in water flow rate (view glossary) for 1 year, for example, from moderately strong (1-3 knots) to very weak (negligible). Further details

Evidence

Decreases in flow rate are unlikely to have any effect as Leptopsammia pruvoti can be found in areas with negligible water flow. Increases in water flow rate may interfere with the ability to feed or to hold the tentacles out in the current. However, a thriving population has been found on the wave exposed west coast of Lundy. Reproduction may be restricted and body condition may be lost as a result of increases in water flow rate. On resumption of 'normal' water flow rates recovery will probably occur within a few months.

Increase in temperature

  1. A short-term, acute change in temperature; e.g., a 5°C change in the temperature range for three consecutive days. This definition includes ‘short-term’ thermal discharges.
  2. A long-term, chronic change in temperature; e.g. a 2°C change in the temperature range for a year. This definition includes ‘long term’ thermal discharges.

For intertidal species or communities, the range of temperatures includes the air temperature regime for that species or community. Further details

Evidence

Observations from aquaria suggest that the species is very tolerant to temperature increases, tolerating up to about 30 ° C for several days. Similarly, observations from aquaria suggest that, once established it survives in temperatures below its normal range. Leptopsammia pruvoti distribution extends south into the Mediterranean where water temperatures are considerably warmer than in the British Isles. However, the species is at the northern limit of its range and long term chronic decreases in temperature would probably cause death. Gamete production, synchronous gamete production or successful recruitment are very unpredictable and sporadic primarily due to unfavourable environmental conditions. Local recruitment has not been recorded at Lundy during more than 12 years of monitoring but occurred to a small extent in 1998.

Evidence

Leptopsammia pruvoti tends to inhabit low light environments such as caves, crevices and overhangs. In the Mediterranean the species is found in very dark conditions (Riedl, 1966). If the presence of some light is of critical importance, increased light transmission may mean that (if recruitment occurs) the species can extend its depth range (In the clear waters of the western Mediterranean the lower depth limit is 40m as opposed to 30m elsewhere.

Abrasion & physical disturbance [Show more]

Abrasion & physical disturbance

Benchmark. Force equivalent to a standard scallop dredge landing on or being dragged across the organism. A single event is assumed for assessment. This factor includes mechanical interference, crushing, physical blows against, or rubbing and erosion of the organism or habitat of interest. Where trampling is relevant, the evidence and trampling intensity will be reported in the rationale. Further details.

Evidence

The calcified skeleton of this species is brittle. Physical disturbance or abrasion would cause detachment and death. Gamete production, synchronous gamete production, or successful recruitment are very unpredictable and sporadic primarily due to unfavourable environmental conditions. Local recruitment was not recorded at Lundy during more than 12 years of monitoring but occurred to a small extent in 1998. Local recruitment is likely but may also occur from distant water bodies perhaps every 25-30 years. There has been no observation of colonization of wrecks or new natural surfaces near to existing colonies such as the breakwater at Plymouth Sound constructed in the early 1800's (Keith Hiscock pers obs.).

Synthetic compound contamination

Sensitivity is assessed against the available evidence for the effects of contaminants on the species (or closely related species at low confidence) or community of interest. For example:

  • evidence of mass mortality of a population of the species or community of interest (either short or long term) in response to a contaminant will be ranked as high sensitivity;
  • evidence of reduced abundance, or extent of a population of the species or community of interest (either short or long term) in response to a contaminant will be ranked as intermediate sensitivity;
  • evidence of sub-lethal effects or reduced reproductive potential of a population of the species or community of interest will be assessed as low sensitivity.

The evidence used is stated in the rationale. Where the assessment can be based on a known activity then this is stated. The tolerance to contaminants of species of interest will be included in the rationale when available; together with relevant supporting material. Further details.

Changes in nutrient levels

Evidence

Changes in nutrient concentration are unlikely to affect this species greatly unless there is a smothering effect through enhanced growth of ephemeral algae. High calcium levels may benefit skeleton construction. On removal of the factor, death of the algae etc and resumption of normal feeding, water flow etc, return to original condition should take only a short time.

Increase in salinity [Show more]

Increase in salinity

  1. A short-term, acute change; e.g., a change of two categories from the MNCR salinity scale for one week (view glossary) such as from full to reduced.
  2. A long-term, chronic change; e.g., a change of one category from the MNCR salinity scale for one year (view glossary) such as from reduced to low. Further details.

Evidence

The species is only found in fully saline environments and at depths unlikely to be affected by freshwater surface runoff (10-30m). Observations from aquaria suggest that these animals are quite tolerant to slight changes in salinity but reductions of one or two salinity bands are likely to cause death. Gamete production, synchronous gamete production or successful recruitment are very unpredictable and sporadic primarily due to unfavourable environmental conditions. Local recruitment has not been recorded at Lundy during more than 12 years of monitoring but occurred to a small extent in 1998.
