Wrasses (Labridae) are the second largest family of fishes on the Great Barrier Reef (after the Gobiidae) and, in terms of morphology and lifestyle, one of the most diverse. They occupy all zones of the reef from the very shallow reef flats to deep slopes, feeding on a variety of fauna. Many wrasses also have elaborately patterned bodies and reflect a range of colours from ultraviolet (UV) to far red. As a first step to investigating the visual system of these fishes we measured the transmission properties of the ocular media of 36 species from the Great Barrier Reef, Australia, and Hawaii, California and the Florida Keys, USA. Transmission measurements were made of whole eyes with a window cut into the back, and also of isolated lenses and corneas. Based on the transmission properties of the corneas the species could be split into two distinct groups within which the exact wavelength of the cut–off was variable. One group had visibly yellow corneas, while the corneas of the other group appeared clear to human observers. Five species had ocular media that transmitted wavelengths below 400 nm, making a perception of UV wavelengths for those species possible. Possible functional roles for the different filter types are discussed.

The spatial and temporal patterns of recruitment of seven species in six families of polychaete to coral substrates at two sites at Lizard Island, Great Barrier Reef, are described. Four species exhibit similar patterns of recruitment to both sites, and another species exhibits a similar pattern to both sites but with different intensities. The other two species recruit in different patterns to the two sites. All species exhibit peaks of recruitment, most during mid-summer. Recruitment during 1977 was significantly greater than during 1976 for five of the seven species. Factors responsible for this variation and the patchiness of successful settlement are discussed.

The genus Lithotrya G. B. Sowerby, 1822, comprises a group of pedunculate barnacles that have developed a rock- or shell-boring habit. Darwin dealt at considerable length with the genus in his Ray Society monograph in 1851, and since then only one new species has been described— L. pacifica Borradaile, 1900. In 1926, however, Seymour Sewell showed that, apart from one doubtful species, L. rhodiopus (Gray), all the others could be divided into two groups. One group of five, he suggested, constituted, in fact, a single species, L. dorsalis (Ellis). The other group of two I dealt with systematically in my report on the Great Barrier Reef Expedition collection (Cannon 1935) and came to the conclusion that they also represented a single species, L. valentiana (Gray). The material on which this paper is based consists mainly of a few specimens of L. valentiana , collected and fixed in Bouin, which were very kindly given to me by Professor C. M. Yonge. I have also to thank Dr L. A. Borradaile for specimens of L. dorsalis collected by him in the Maldive Islands in 1900, and the Discovery Committee for specimens of various barnacles which I have used for comparison. In addition, I still have the official collection of the Great Barrier Reef Expedition, and a few of these have now been sectioned. I have been careful, however, not to section critical specimens of my detailed list (Cannon !935, p. 5, table 1).

Typton australis Bruce, 1973 was described from the Great Barrier Reef, Australia. The species was referred to the genus Typton Costa, 1844 increasing the diversity of the genus in Indo-West Pacific region to six species. At the same time, T. australis shows a developed blade of the scaphocerite and absence of any ornamentation on the orbital and anterolateral margins of the carapace (Bruce 1973, 2000), whereas the type species of the genus Typton, T. spongicola Costa, 1844, possesses well-developed so-called “paraorbital” teeth (Bruce 1972, 1977; I. Marin, pers. observ.). Complete absence of any ornamentation on the orbital and anterolateral margins of the carapace is also known for Typton capricorniae Bruce, 2000 but the blade of the scaphocerite of this species is almost completely reduced as in the other species of the genus Typton.

Rate Of Movement

Two series of outbreaks of the crown-of-thorns starfish, Acanthaster planci (L.), have been recorded on the Great Barrier Reef since the early 1960s. Data from scientific surveys and reliable unpublished observations were analysed statistically to quantify the pattern of movement of these outbreaks. Data on outbreak populations were obtained from 84 and 97 reefs for the periods 1966-74 and 1979-91, respectively. Outbreaks during the former period were found to occur further south with time, their rate of movement increasing from 49 km year-1 in 1966 to almost 81 km year-1 by 1974. Two sets of outbreaks were identified during the 1979-91 period, one occurring to the north, and the other to the south, of latitude 16�s. The 'southern drift' in outbreaks was found to be the more dominant of the two, 'travelling faster' for a greater period. Its initial rate of movement was estimated at 77 km year-1 compared with 57 km year -1 for the 'northern drift'. The latter travelled 150 km before it stopped in 1984. In contrast, the 'southern drift' had travelled a distance of 560 km by 1991, although it had also become almost stationary by then. Outbreaks that moved south during 1979-91 followed a path similar to those that occurred in the 1966-74 period. This similarity in the outbreak paths was particularly evident during the first 6 years of each period. In all, 35 reefs were recorded as experiencing both outbreaks, the average time between each being 14.68 years. The origin of the northern and southern patterns in the 1979-91 period was found to coincide, suggesting that the likely epicentre for primary outbreaks is close to latitude 16�s.

The One

In 1626 Samuel Purchas published an anthology of travel stories which included an account by François Pyrard de Laval of his shipwreck on a coral reef in the Maldives for 5 years in the first decade of the seventeenth century. Purchas translates Laval's account of the coral atolls as follows:<br />All the shallowes are stone, Rocke and sand, so that when the tide is out, it reacheth not to ones waste, and for the most part to the mid-legge; so that is were very easie to goe wihtout a Boate throughout all the Isles of the same Atollon, if it were not for two causes. The one great fishes called Paimones, which devoure men and breake their legges and armes, when they encounter them; the other is that the depths of the Sea are generally very keene and sharpe Rockes which hurt them wonderfully that goe into it. And moreover they meete with many branches of a certaine thing which I know not whether to terme Tree or Rocke, it is not much unlike white Corall, which is also branched and piercing, but altogether polished; on the contrary, this is rugged, all hollow and pierced with little holes and passages, yet abides hard and ponderous as a stone. (Purchas, vol IX, 509).

A remarkable example of an exhumed Middle to Late Devonian barrier-reef belt extends for about 350 km along the northern margin of the Canning basin in Western Australia. The reefs form a series of rugged limestone ranges cut by deep river gorges which provide spectacular sections through the reefs and associated facies. The gross morphology of the ranges and intervening valleys closely resembles that of the Devonian seafloor, so that from the air the reefs are displayed much as they were in Devonian time.The Canning basin reef complexes offer exceptional opportunities for carbonate research because of the excellence of exposures and the wide variety of facies represented; moreover the rocks are little deformed, are not dolomitized extensively and are unmetamorphosed. Some facies have undergone significant compaction through stylolitization; however, most structures and textures in the limestones can be shown to have had depositional or early diagenetic origins.The reef complexes developed as reef-fringed limestone platforms flanked by marginal-slope and basin deposits. They were built by stromatoporoids, algae, and corals in the Givetian and Frasnian and by algae in the Famennian. The platform and basin facies were laid down nearly horizontally, whereas the marginal-slope facies accumulated with steep depositional dips away from the platform. Marginal slopes commonly were as high as 35° in loose talus and were up to vertical where algal binding occurred in association with early lithification. Geopetal fabrics quantify depositional and tectonic/compactional components of observed dips for paleobathymetric studies of the complexes and their fossil biotas.Four main types of platform margin are present: retreating, back-stepping, upright and advancing. The advancing type is characteristic of the Famennian platforms, whereas the other three are typical of the Frasnian. Pinnacle reefs developed during periods of rapid subsidence, especially during the middle Frasnian, are associated with back-stepping and retreating platform margins.Very early submarine cementation was widespread around the platform margins and on parts of the marginal slopes, but it was not generally extensive in the platform interiors. Early fracturing of reef limestones along the platform margins, probably associated with earthquakes, resulted in the development of neptunian dikes and the collapse of some sections of the reef as submarine rockfalls. These often initiated massive debris flows, many of which carved channels in and, somewhat deformed, the underlying marginal-slope deposits.
