This chapter describes the physical setting, biogeography, El Niño cycle and climate change effects of the coral reefs of Panama. A focus on the unique role of low diversity but complex ecological interactions, as well the importance of corals in supporting a diverse and often cryptic part of the food web is presented. Spatial and temporal variation is described as well as the potential role of human resource use and climate change on the ecosystem.

This chapter explains the success of companies such as Provident Financial and Cattles (both members of the FTSE 250 by the 1990s). Their agents serviced the growing sub-prime sector and commercialized backstreet feminized affectual relationships between borrowers and lenders. The extent to which their success was dependent on the decline of pawnbroking and mail order agency (and the limitations of the government's Social Fund) is explained. The motivations and limited options of moneylenders' customers are explored as are accusations of ‘predatory lending’ and exploitation. Moneylenders fought PR battles to exclude themselves from the label ‘loan shark’, as images of criminal moneylenders increasingly replaced ones of ‘Shylocks’. The chapter examines the role of violent loan sharks, explaining their small but significant market. Particularly important was the fact that government resisted calls for interest rate caps because it feared legal lenders would abandon their riskiest borrowers, leaving them vulnerable to loan sharks.

In recent years, with better education and a more transparent approach to public engagement, our knowledge and understanding of the shark have improved such that coastal visitors and locals alike are more likely to see the presence of sharks as not only an indicator of ecosystem health, but also as an economic opportunity. Human responses like those that occurred in 1916, or even in the 1960s, have changed drastically. Rather than rely on ignorance and the distorted “man-eater” myth and cinematic tropes of shark violence, people are beginning to recognize that the predatory nature of sharks is natural and that sharks have greater rights to the ocean than tourists do. The appeal of shark ecotourism suggests that even though sharks are feral and can be scary, our unfamiliarity with them makes our curiosity trump that fear. This amazing shift in attitude has made the move away from hunting sharks with dynamite, guns, and longlines to hunting sharks with cameras a logical one. By rebranding the shark and seeing it as natural capital, their presence in the world’s oceans can be understood as another asset we must tend to.

This chapter is an evocation of the fishing village of Boca San Michel, near Willemstad and tells the story of the death of Max Zimmerman, one of its fishermen and neighbour to the author including a description of a death procession and being laid to rest with to the strains of a muffled tambú drum playing.

This chapter examines historical films produced in Hollywood about the life and death of American president Abraham Lincoln made during the period from 1930 to 1941. During this period, Lincoln's presence sanctified whatever theme or subject the historian chose and he generously supported whatever period film a studio happened to create. Lincoln lent authenticity to insignificant scripts, healed any divisive tale of the Civil War and he was a prestigious touch added to secure that elusive critical and box-office appeal. Examples of these films include D.W. Griffith's Abraham Lincoln, Darryl Zanuck and Nunnally Johnson's The Prisoner of Shark Island, and John Ford's Young Mr. Lincoln.

Symbols like the service flag furthered community morale in the United States during World War I and evolved to engender memorial organizations like Gold Star Mothers. Music supported both, with three components of the industry—Tin Pan Alley, Kitchen Table publishing, and Song Sharks—differing in key respects: the participation of women composers and lyricists, the focus on mothers and loss, and the mix of ballads, waltz songs, and marches. As the war evolved, so did the responses, with the closing months and aftermath focusing increasingly on soldiers’ fatalities and the expression of grief and mourning. Postwar changes in style and dissemination marked the end of such collective expressions.

Fossils potentially provide direct evidence on how changes in growth strategies may have affected diversification patterns in geologic time. New strategies may have allowed some species to exploit new ecological opportunities or contributed to their demise. This chapter discusses the following topics: ocean acidification in the past and today; major patterns of larval evolution in the oceans; climate change and mammalian developmental evolution; Jurassic sharks; survival and diversification in the early mammalian lineage; and islands as experiments in life history evolution.

The Ulysses expedition killed 2,037 whales and processed approximately 79,000 barrels of oil in Shark Bay, Australia, during the first equatorial season of its career. The Ulysses processed her whales and manufactured the whale oil within the territorial limits of Australia and within the port limits of Carnarvon, Western Australia. At this time the people in authority on this expedition were apparently not terribly interested in adhering to the requirements of United States whaling regulations. Observations indicate that there was a growing animosity on land toward whaling ships of foreign registry operating off the Australian coast. The Australians were deriving very little financial return from the two expeditions. This is understandable since the whaling ships were making thousands of dollars daily off the Australian coast. The Ulysses bought tons of provisions and tons of water while off the coast of Australia.

Virtually all the whales obtained in Shark Bay were delivered to the factory ship on the same day as they had been killed; toward the end of the season some carcasses were delivered after midnight, but such instances were comparatively few and far between and no exceptions were made on the records. The expedition's killer boats were allowed to take only an allotted number of whales daily, the number being determined by the factory shop manager. This system prevailed for most of the season. The Australian records was examined every morning by the American inspector. Strictly speaking, the Ulysses had little to do with the actual formulation of Form WI-1 as an official record for the United States government. In Antarctica, the company's disregard for maintaining this form in an accurate manner was even more pronounced. The method of recording the data is in need of some explanation, which this chapter attempts to give.

This chapter focuses on the large animals found in the sea. It describes their evolutionary history and patterns of behavior such as feeding, breeding, and migration. Cetaceans as a group (whales and dolphins) are the largest and the fastest swimming animals in the sea. Both toothed whales and those lacking teeth have enormously large representatives, but the largest are baleen whales. The largest of the toothed cetaceans is the sperm whale (Physeter macrocephalus), while the blue whale (Balaenoptera musculus) is the largest among the baleen whales. The baleen whales, together with the giant sperm whale, are called great whales. Other vertebrate groups also have large animals: pinnipeds have elephant seals and the walrus; sharks and their kin include whale sharks; the great white, and manta rays; and bony fishes have swordfish and sturgeon. Among the mollusks, the giant squid is the largest.

This chapter examines the early vertebrates. The major group to which vertebrates are assigned—phylum Chordata—includes two small groups (the tunicates and the cephalochordates) and one large group: the vertebrates (or Craniata). Most chordates are bilaterally symmetrical, with complete, relatively complex digestive tracts. There are nine major groups of vertebrates, five of them “fishes” and four of them tetrapods. Although chordates constitute only some three percent of all living species, they are widely distributed, marvelously adapted, numerically abundant, and strikingly successful. All share a few distinguishing characteristics for at least part of their development: a single hollow nerve cord, which is differentiated in vertebrates into the brain and spinal cord; a notochord, a flexible rodlike axis, running underneath and supporting the nerve cord; pharyngeal gill slits; a tail extending beyond the anus; and segmentation, reflected in the muscles and the vertebral column.

This chapter analyzes how aspiring migrants navigate the world of document fixers, loan sharks, travel agents, lawyers, and state bureaucrats—including consular staff and U.S. immigration officials—in preparation for international migration. It presents accounts of the institutions, technologies, social and cultural forms, and relationships that shape and constrain migrants' efforts. Migrants of provincial and lower-class backgrounds often extend themselves through objects, technologies, and embodied skills to realize their migration projects; they do so with guidance from tramitadores (document fixers) and other service providers in Peru's growing migration industry. The chapter also discusses the complex politics of race and class that underline the historically unequal access to mobility in Peru, and in turn intersects with U.S. racialization of Latin American migrants that begins with their first encounters with U.S. consular staff in Lima.

This chapter discusses the anatomy of the brains of the cartilaginous fishes and their learning capabilities. Sharks, rays, and chimaeras can learn as quickly as birds and mammals, and have brains of a comparable size and elaboration.

This chapter discusses the courtship behavior and reproductive biology of sharks and rays. It covers the spermatogenesis and sexual maturation of male sharks and rays; sexual maturation and embryonic development of female sharks and rays; the reproductive cycle; courtship and copulation; and promiscuity and multiple paternity.

This chapter discusses the anatomy of the jaws and teeth of cartilaginous fishes as well as the role of the muscles and teeth in jaw extension, seizure, and handling of prey. Most sharks, rays, and chimaeras are tertiary consumers, occupying the same trophic level as the prey of the white shark. These species feed upon small fishes, cephalopods, and mollusks that in turn feed on zooplankton. There are three steps in active predation: approach, seizure, and handling of the prey. The extent of attachment of the jaws to the cranium has lessened over evolutionary time in the cartilaginous fishes. The ancient sharks needed to swallow their prey whole due to the rigid attachment of the jaws to the cranium. The jaws of the modern sharks trend toward a less rigid attachment to the cranium.

This chapter discusses the diverse types of movement patterns exhibited by sharks and rays. Some elasmobranchs are ambushers, and their movements are restricted to a confined area. Many skates, some stingrays, and angelsharks remain in wait on the bottom for long periods of time to ambush crabs and shrimps or fishes that walk or swim close to the bottom. Many cartilaginous fishes exhibit two types of travel modes, performing highly directional and rapid movements as they migrate between resting or foraging locations, and then exhibiting randomly directed slow movements when interacting socially or foraging at their feeding grounds. During their migrations, these species display two types of swimming behaviors, oscillatory diving and surface swimming.

This chapter discusses the interactions between the cartilaginous fishes and humans. It describes the risk of being bitten by a shark or being impaled by the barb of a stingray and the growing interest of ecologically aware tourists in viewing sharks underwater. It recounts a few infamous shark attacks to illustrate the severe economic repercussions of such a highly publicized mishap; explains the motivations behind this behavior; it also places the modest risk of shark attack in the context of many other greater risks in daily life. The chapter also considers the economic value of shark and ray ecotourism, and provides information on what species can now be viewed underwater and where to go to see them.

This chapter focuses on the recent expansion of fisheries for sharks and rays, and the decline of the populations of sharks and rays in the world's oceans. It describes historical examples of the collapse of shark fisheries; the methods of managing elasmobranch fisheries including recent regulations; and the recent establishment of reserves to protect sharks and rays. It suggests that the factors which made the sharks, rays, and chimaeras so successful over time also have made them very vulnerable today in a world dominated by humans.
