Microplastics in marine mammals stranded around the British coast: ubiquitous but transitory?

The Encyclopedia of Marine Mammals , Third Edition covers the ecology, behavior, conservation, evolution, form and function of whales, dolphins, seals, sea lions, manatees, dugongs, otters and polar bears. This edition provides new content on anthropogenic concerns, latest information on emerging threats such as ocean noise, and impacts of climate change.

With authors and editors who are world experts, this new edition is a critical resource for all who are interested in marine mammals, especially upper level undergraduate and graduate students, researchers, and managers, and is a top reference for those in related fields, from oceanographers to environmental scientists. His specialties are behavior and social strategies, especially as related to human disturbance.

He has published and co-published about peer review papers, over 50 popular articles, and 7 books. His work with the sense organs of modern whales explores the impact of global change on marine mammal populations.

Kit M. She has worked with marine mammals in Polar Regions for the past 30 years, focusing primarily on studies in the fields of behavioral ecology and population biology. The impact of climate change on ice-associated species has been a topic of principal concern in recent years in her research projects. Account Options Anmelden.

Seafood is any form of sea life regarded as food by humans, prominently including fish and shellfish. Shellfish include various species of molluscs e. Historically, marine mammals such as cetaceans whales and dolphins as well as seals have been eaten as food, though that happens to a lesser extent in modern times. Edible sea plants such as some seaweeds and microalgae are widely eaten as sea vegetables around the world, especially in Asia.

Rhincodon typus

These sharks are recognizable not just for being the largest fish in the sea, growing longer than 40 feet, but also for their unique pattern of blue-gray to brown coloration with white spots centered between pale horizontal and vertical stripes. They are filter feeders, often swimming near the surface of the open sea, gulping in water and filtering everything from plankton and fish eggs, to crustaceans and schooling fish, to occasional larger prey like squid or tuna. Despite their size, they are considered harmless to humans, and will often interact docilely with divers to the extent of allowing the divers to grab on to a fin and hitch a ride. Whale shark , basking shark, and whaleshark are common names in the English language used to refer to this fish. In the past, the whale shark has been of little interest to man. At present, commercial fisheries for whale sharks are limited, but may expand from an increased demand for food products. In Taiwan approximately whale sharks are taken annually.

A highly intelligent group of ocean dwelling creatures, the living cephalopods include the eight-armed octopuses, the ten-armed squids and cuttlefishes, and the shelled chambered nautiluses. Early in their evolution, cephalopods relied on the sturdy protection of shells, but over time many eventually lost the outer shell and instead relied on new adaptations like heightened intelligence, a talent for hiding, and strong, flexible arms.

Learn which whales were hunted and why; how they captured and processed them; how technology changed the industry. Whaling was an exceptionally dangerous business both physically and economically. In the Yankee whale fishery injuries and death were common to almost every voyage. Many vessels were lost. Few individuals got rich whaling and most of those were owners and agents. The answers to why so many people went whaling are many and varied but the underlying principle is that whale products had a strong commercial value if one knew how to exploit it. KWM In Men and Whales , Richard Ellis writes that, until the beginning of the twentieth-century, whaling was considered an admirable occupation. Oil was needed for light and lubrication; baleen was needed for skirt hoops and corset stays.

Only millimetres in length, these crustacea are fearsome hunters, marvels of evolution and possessed of the nearest thing we know to superpowers. Instead, the pistol shrimp sports one outsize claw which it can snap almost exactly like snapping fingers to generate a shockwave that can stun or kill even much larger animals, including fish. This unlikely ability makes this tiny animal the loudest creature on the planet, louder even than sperm whales whose entire cranial anatomy has evolved to produce high energy sonar clicks and beluga whales, the opera singers of the seas. Pistol shrimp are so loud that they interfere with submarine navigation.

Our oceans are a marvel — alive with color, noise, drama, curious life forms, and fascinating creatures — and that is just what we know about today! Every day, scientists learn more about the wonders beneath the waves.

Ospreys are an indicator species. The health of their population has implications for the health our coastal ecosystems. The fin whale is a large baleen whale. It is the second largest animal alive today - only the blue whale is larger. It may reach a length of up to 75 feet in the Northern Hemisphere and 85 feet in the Southern Hemisphere.

Mercury in fish

Commercial fishing , the taking of fish and other seafood and resources from oceans, rivers, and lakes for the purpose of marketing them. In the early 21st century about million people were directly employed by the commercial fishing industry, and an estimated one billion people depended on fish as their primary source of animal protein. Fishing is one of the oldest employments of humankind. Ancient heaps of discarded mollusk shells, some from prehistoric times, have been found in coastal areas throughout the world, including those of China, Japan, Peru, Brazil, Portugal, and Denmark.

Fish and shellfish concentrate mercury in their bodies, often in the form of methylmercury , a highly toxic organomercury compound. Fish products have been shown to contain varying amounts of heavy metals, particularly mercury and fat-soluble pollutants from water pollution. Species of fish that are long-lived and high on the food chain , such as marlin , tuna , shark , swordfish , king mackerel and tilefish Gulf of Mexico contain higher concentrations of mercury than others. Mercury is known to bioaccumulate in humans , so bioaccumulation in seafood carries over into human populations, where it can result in mercury poisoning.

Wild salmon are a nitrogen pump in B. The wild salmon transport ocean-based nitrogen up rivers and fertilize the growth of ancient temperate rainforests. Salmon are a key stone species, which means entire ecosystems are dependent on their health. Seals, whales, bears, eagles and other species also rely on wild salmon for sustenance.
