It is this ubiquity, coupled with their brilliant colouration and fused ‘beak-like’ jaws, that have long attracted the attention of those looking and working on tropical reefs. Parrotfishes also have an incredibly diverse and complex array of reproductive and mating strategies that vary both among and within species. However, it is their unique feeding action that has stimulated much scientific endeavour. The morphological innovations of the oral jaws allow parrotfishes to bite through reef carbonates, while the pharyngeal jaws allow them to grind ingested carbonates into sand particles. These innovations not only enable parrotfishes to access nutritional resources that are largely unavailable to other fishes, but make them one of the most important groups of fishes within coral reef ecosystems. No other group of fishes is so inextricably linked to the structural dynamics of their ecosystem. Despite their importance to reef ecosystems, the threats to parrotfish are numerous and severe: from the global effects of ocean warming and acidification to the local effects of overfishing, pollution and habitat degradation. The aim of this book is to synthesise what is currently known about the biology of parrotfishes, and to consider why are parrotfishes so important to the ecology of coral reefs? The book provides a series of reviews that are intended to provide a firm grounding in the understanding of the morphology, diet, demography, distribution, functional ecology, and current threats of this group. Importantly, it provides new insights into their diet and food processing ability, their life-histories, and the influence of habitat and environment on parrotfish populations, and also identifies emerging research topics and future directions. We hope this book will appeal to students, early-career and established researchers, alike, and will stimulate further investigation into this fascinating and unique group of fishes. Lastly, we wish to thank to all of those who contributed to this book. We invited the international authorities on various aspects of the biology of parrotfishes to contribute to the book and were overwhelmed by their positive and enthusiastic responses. We would also like to thank David Bellwood for initiating our interest in parrotfishes, sharing his extensive knowledge, and guiding our scientific development. We sincerely thank the reviewers of each chapter of this book for their constructive and insightful comments. Finally, we are extremely grateful for the ongoing support from our families (especially

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region. Introduction and finally a complex geologic past highlighted The region consisting of eastern Indonesia, East by shifting island arcs, oceanic plate collisions, Timor, Sabah, Philippines, Papua New Guinea, and widely fluctuating sea levels (Polhemus and the Solomon Islands is the global centre of 2007). reef fish diversity (Allen 2008).

Here, we accessed the LEK of recreational anglers and recreational spearfishers to investigate the increase in the abundance of five northward expanding indigenous thermophilic fish species in two subregions of the Mediterranean Sea: the Adriatic/Ionian Seas and the Tyrrhenian/Ligurian Seas. We used an online survey administered through Twitter and Facebook between 2017 and 2018 to both Italian and Croatian recreational fishers. A total of 794 respondents completed the questionnaire (386 from the Adriatic/Ionian subregion and 408 from the Tyrrhenian/Ligurian one). Overall, the species perceived as most increasing in abundance were Pomatomus saltatrix (71% of replies) followed by Sphyraena

Twenty-two reciprocally monophyletic sister- species pairs were identified: 64% were allopatric, and the remainder were sympatric. Age of divergence was similar for allopatric and sympatric species pairs. Sympatric sister pairs displayed greater divergence in morphol- ogy, ecology, and sexually dimorphic colour patterns than did allopatric pairs, suggesting that both genetic drift in allopatric species pairs and ecologically adaptive divergence between members of sympatric pairs have played a role in diversification. Basal species typically have small geographical ranges and are restricted to geographically and ecologically peripheral reef habitats. We found little evidence that a single dominant process has driven diversification, nor did we detect a pattern of discrete, sequential stages of diversification in relation to habitat, ecology, and reproductive biology. The evolution of Chlorurus and Scarus has been complex, involving a number of speciation processes.

A.D. / 1424 A.H.) 23 Fish Fauna of the Jordanian Coast, Gulf of Aqaba, Red Sea MAROOF KHALAF Marine Science Station, University of Jordan- Yarmouk University, Jordan E-mail: [email protected] ABSTRACT. This paper presents a fish inventory of the Jordanian Gulf of Aqaba. Fish sampling was conducted by means of different fishing gears, monitoring of local fish market and visual census technique. A total of 507 fish species belonging to 109 families with an average of 4.7 species per family; 18 Chondrichthyes and 489 Ostichthyes. The largest families are as follows (number of species in parentheses): Lab- ridae (51), Pomacentridae (29), Serranidae (25), Apogonidae and Blen- niidae (24, each), Gobiidae (21), Carangidae (17) and Syngnathidae (16). Collectively these eight families comprise 40.8% of the fish fau- na. The great majority are from benthic habitat (82.8%) and the remaining are pelagic fish. About 30.6% of the fish species feed on in- vertebrates and fish while 24.8% feed on invertebrates only. The en- demic species present 12.8% of the recorded species in the Gulf of Aqaba, and this is slightly less than the percentage of endemic species in the Red Sea and Gulf of Aden, 13.7%. On the Jordanian part of the Gulf of Aqaba seventy six fish species are reported for the first time. Out of them Gymnothorax monochrous, Myripristis xanthacra, Cory- thoichthys haematopterus, Syngnathus macrophthalmus, Istiblennius flaviumbrinus, Enneapterygius destai and Grammatorycnus bilineatus species are first confirmed report for the first time in the entire Gulf.

An extensive collection of fishes from lord Howelsland was made during a month's expedition in February 1973. A total of 208 species are newly recorded from lord Howe Island and 23 species newly recorded from the Australian mainland. The fish fauna of lord Howe is increased to 447 species in 107 families. Of the 390 species of inshore fishes, the majority (60%) are wide-ranging tropical forms; some 10% are found only at lord Howe Island, southern Australia and/or New Zealand.
