Pocillopora damicornis (Linnaeus) were collected from Enewetak Atoll, Marshall Islands, in 1980–1981) and Kaneohe Bay, Hawaii, in 1982. Their planula larvae contained 17% protein, 70% lipid, and 13% carbohydrate by dry weight. Calculations based on stored energy reserves and daily metabolic expenditure indicate that planulae could survive approximately 100 d and still settle successfully. Competency experiments demonstrated that larvae settled and metamorphosed after 103 d. This period of time… 

Settlement-competency periods of larvae of three species of scleractinian corals

Medium to long-distance larval dispersal of the species studied provides a mechanism for their widespread distribution in subtropical regions, on reefs which are often widely spaced and relatively isolated.

Settlement-competency Period of Planulae and Genetic Differentiation of the Scleractinian Coral Acropora digitifera

It is concluded that genetic mixing is not complete in Acropora digitifera, but that some localized planulae may disperse from Kerama to Okinawa via a specific current depending on reef or locality.

Larval dispersal of Pocillopora damicornis at high latitude coral communities

The present study suggests that the planulae of P. damicornis have limited dispersal distances at high-latitudes©.

The energetics of scleractinian coral larvae and implications for dispersal

The energetics of scleractinian coral larvae are investigated to enhance understanding of the dispersal potential of corals, knowledge that is necessary for the design of marine protected areas and other management strategies needed to protect coral reefs.

Larval survivorship, competency periods and settlement of two brooding corals, Heliopora coerulea and Pocillopora damicornis

Brooding corals exhibit variations in larval dispersal patterns, which are characterized by their position in the water column and competency periods, and may have a narrower dispersal range than those of P. damicornis, settling and recruiting near parent colonies.

Experimental analysis of recruitment in a scleractinian coral at high latitude

It is demonstrated that the planulae of brooding coral species do not generally disperse over long distances at high latitude.

Trophic biology of Stylophora pistillata larvae: evidence from stable isotope analysis

It was found that planula larvae of the coral Stylophora pistillata were depleted in 13 C when compared to parental tissues, whereas their C/N ratios were 2-fold higher, and following 2 wk of starvation in the dark, planulae started to utilize their lipid and protein reservoirs.

Reproductive biology, development, and planula behavior in the Caribbean gorgonian Pseudopterogorgia elisabethae

The reproductive biology, development, and planula behavior of the gorgonian Pseudopterogorgia elisabethae were studied at 2 sites in the Bahamas between 1996 and 2001 and field observations suggest that larvae may settle within tens of meters of the maternal colony.

Planulation periodicity, settlement preferences and growth of two deep-sea octocorals from the northwest Atlantic

Dual traits of resilience and vulnerability are highlighted in deep-sea corals by showing that planulae set- tled more readily on rough natural surfaces covered with biofilm than all other substrata tested and that larvae of colonies from deeper habitats were less selective than those originating from shallower habitats.

Rapid declines in metabolism explain extended coral larval longevity

The capacity of non-feeding coral larvae to enter a state of low metabolism soon after becoming competent to metamorphose significantly extends dispersal potential, thereby accruing advantages typically associated with planktotrophy, notably enhanced population connectivity.



Long-Lived Larvae of the Gastropod Aplysia juliana: Do They Disperse and Metamorphose or Just Slowly Fade Away

The planktonic larvae of the opisthobranch Aplysia juliana stop growing about 30 d after release from the egg, and both tissue and shell mass remain at a plateau in excess of 200 d, which suggests that these larvae are capable of long-dance dispersal by major ocean currents.

Long-distance dispersal and the reef-building corals of the Eastern Pacific

This work suggests that the available evidence does not strongly support this biogeographic hypothesis, and proposes an alternative hypothesis based upon modification of a previously widespread, pan-Tethyan coral biota which has since been modified by tectonic events, speciations, and extinctions.

Types of larval development in marine bottom invertebrates, their distribution and ecological significance: a re-evaluation

The distributional patterns of the various types of development among marine bottom invertebrates form one of the most important factors determining the basic distributional dynamics of the whole benthos in all oceans, both in the geological past and at the present time.

An energy budget for the free-swimming and metamorphosing larvae of Balanus balanoides (Crustacea: Cirripedia)

Cypris larvae of Balanus balanoides (L.) lose their competence to metamorphose successfully approximately at the same time (3 to 4 weeks) that the energy supply for swimming and exploration is used up.

Diversity and Age Patterns in Hermatypic Corals

Diversity and average generic age distributions for hermatypic corals show that while the Atlantic and Indo-Pacific faunas have evolved at different rates and in some respects have long been isolated systems, many responses to environment are the same.


1. Ten species of prosobranch gastropod veligers collected from the open waters of the North Atlantic Ocean have been identified by comparison of their larval shells with the protoconchs of

Population genetics of eight species of Trapezia (Brachyura: Xanthidae), symbionts of corals

Starch-gel electrophoresis was used to study gene-enzyme variation in thirteen populations of eight species of the genus Trapezia from Hawaii, Panamá, and Enewetak Atoll, and low values of genetic distance among species suggest a recent radiation, perhaps during the Pleistocene.

Development of contemporary Eastern Pacific coral reefs

An overview of oceanographic conditions prevailing in the tropical Eastern Pacific Ocean suggests that the entire region is environmentally marginal for coral-reef development, with a strong, permanent, shallow thermocline and an annual north-south migration of the Intertropical Convergence resulting in wet and dry seasons.

Wax in coral mucus: Energy transfer from corals to reef fishes1

Observation revealed extensive mucus feeding by many species of reef fishes and coral mucus could be an energy source linking the coral producer and small fish consumers in reef communities.
