Yet everybody realized that the seals apparently had enemies of their own, such as the fearsome Ziphius. Here a Ziphius, with a face looking like a cross between an owl’s and a worried human’s, endures a bite from a porcine sea monster while munching on a hapless seal. The Ziphius might have been based on a killer whale or great white shark. Medieval manuscript Image appears at: Unlike the “rapier-billed” animals known as swordfish and sawfish today, the animals bearing these names during the Renaissance might have been inspired by the orca, or killer whale. Growing tired, after racing three or four miles or more, he folds up his wings and the waves carry him back to his former abode where he was at first. The sea is the world, the ships are the prophets and apostles who cross through this world. The swordfish who does not keep pace with the crossing ships represents those who are abstinent for a time but who do not persevere with good pace. These begin with good works but do not persevere to the end because of greed, pride, and love of wicked gain.

The Crimean Peninsula thrusts into the Black Sea from the north, and just to its east the narrow Kerch Strait links the sea to the smaller Sea of Azov. The Black Sea coastline is otherwise fairly regular. The maximum east-west extent of the sea is about miles 1, km , and the shortest distance between the tip of Crimea and Cape Kerempe to the south is about miles km.
The surface area, excluding the Sea of Marmara but including the Sea of Azov, is about , square miles , square km ; the Black Sea proper occupies about , square miles , square km. A maximum depth of more than 7, feet 2, metres is reached in the south-central sector of the sea. To scientists, the Black Sea is a remarkable feature because its lower levels are, to all intents and purposes, almost biologically dead—not because of pollution but because of continued weak ventilation of the deep layers.
To the countries of the region, the Black Sea has been of immense strategic importance over the centuries; the advent of more-settled conditions has brought its economic importance to the fore. Physical features Physiography The coastline of the Black Sea is only mildly indented, except for the northwestern and northern shores, which are low and furrowed by numerous ravines, valleys, and rivers, the mouths of which are often impeded by sandy spits.
The mountains of southern Crimea form the only precipitous cliff areas. In the east and south, the coasts are steep and mountainous.

See Article History Alternative Title: In a more general sense, a carnivore is any animal or plant; see carnivorous plant that eats other animals, as opposed to a herbivore , which eats plants. Although the species classified in this order are basically meat eaters, a substantial number of them, especially among bears and members of the raccoon family, also feed extensively on vegetation and are thus actually omnivorous.
The order Carnivora includes 12 families, 9 of which live on land: Canidae dogs and related species , Felidae cats , Ursidae bear s , Procyonidae raccoon s and related species , Mustelidae weasel s, badger s, otter s, and related species , Mephitidae skunk s and stink badgers , Herpestidae mongoose s , Viverridae civet s, genet s, and related species , and Hyaenidae hyena s. There are three aquatic families: Otariidae sea lion s and fur seal s , Phocidae true, or earless, seal s , and Odobenidae the walrus.
These aquatic families are referred to as pinniped s. Lions Panthera leo engaging in various activities such as hunting, eating, grooming, and sleeping. Importance of Carnivora Two carnivores are probably the animals most familiar to people:

Seafood is any form of sea life regarded as food by humans. Seafood prominently includes fish and ish include various species of molluscs, crustaceans, and ically, sea mammals such as whales and dolphins have been consumed as food, though that happens to a lesser extent in modern times. Edible sea plants, such as some seaweeds and microalgae, are widely eaten.
Test biology and Tube feet Sea urchins may appear to be incapable of moving but this is a false impression. Sometimes, the most visible sign of life is the spines, which are attached to ball-and-socket joints and can point in any direction; in most urchins, touch elicits a prompt reaction from the spines, which converge toward the touched point.
Sea urchins have no visible eyes, legs, or means of propulsion, but can move freely but slowly over hard surfaces using adhesive tube feet, working in conjunction with the spines. The test is rigid, and divides into five ambulacral grooves separated by five interambulacral areas. Each of these areas consists of two rows of plates, so the sea urchin test includes 20 rows of plates in total.
The plates are covered in rounded tubercles which contain the sockets to which the spines are attached by ball and socket joints. The inner surface of the test is lined by peritoneum. The spines are usually hollow and cylindrical. Contraction of the muscular sheath that covers the test causes the spines to lean in one direction or another, while an inner sheath of collagen fibres can reversibly change from soft to rigid which can lock the spine in one position.
Located among the spines are several types of pedicellaria , moveable stalked structures with jaws. During locomotion, the tube feet are assisted by the spines which can be used for pushing the body along or to lift the test off the substrate. Movement is generally related to feeding, with the red sea urchin Mesocentrotus franciscanus managing about 7. An inverted sea urchin can right itself by progressively attaching and detaching its tube feet and manipulating its spines to roll its body upright.
These are characterised by their big tubercles, bearing large radiola Close-up of the test showing an ambulacral groove with its two rows of pore-pairs, between two interambulacra areas green.

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods.
We are told that of all the radiometric dates that are measured, only a few percent are anomalous.

History of seafood The harvesting, processing, and consuming of seafoods are ancient practices with archaeological evidence dating back well into the Paleolithic. During this period, most people lived a hunter-gatherer lifestyle and were, of necessity, constantly on the move. However, where there are early examples of permanent settlements though not necessarily permanently occupied such as those at Lepenski Vir , they are almost always associated with fishing as a major source of food.
The ancient river Nile was full of fish; fresh and dried fish were a staple food for much of the population. Some representations hint at fishing being pursued as a pastime. World fisheries harvest, both wild and farmed, in million tonnes, —  World fisheries harvest, wild capture versus aquaculture production, in million tonnes —  Fishing scenes are rarely represented in ancient Greek culture, a reflection of the low social status of fishing.
However, Oppian of Corycus , a Greek author wrote a major treatise on sea fishing, the Halieulica or Halieutika, composed between and This is the earliest such work to have survived to the modern day. The consumption of fish varied in accordance with the wealth and location of the household. In the Greek islands and on the coast, fresh fish and seafood squid , octopus , and shellfish were common.
They were eaten locally but more often transported inland. Sardines and anchovies were regular fare for the citizens of Athens. They were sometimes sold fresh, but more frequently salted. A stele of the late 3rd century BCE from the small Boeotian city of Akraiphia, on Lake Copais , provides us with a list of fish prices.

TAS Up to five new fish species are among a haul of thousands of fish collected from the dark depths of Australia’s eastern abyss. Scientists on board the research ship Investigator collected 42, fish and invertebrate specimens from ocean depths of up to 4, metres during a voyage last year. Among their most interesting findings was the rediscovery of the “faceless” fish, as well as blob fish, bioluminescent cookie-cutter sharks and the lizard fish.
More than different fish species collected on the voyage are now being examined at the CSIRO in Hobart to determine which of them are new to science. The marine species were taken from Australia’s eastern abyss, the largest and deepest habitat on the planet. He described the voyage as “frontier science” which was vital for increasing the understanding of the deep-sea environment.
Mr Pogonoski said discovering a new species was both exciting and challenging. Mr Pogonoski said out of the species collected, about 10 per cent were new records for Australia, and about 5 per cent were potentially completely new to science. Scientists have been probing more than 42, fish and invertebrate species collected on the voyage over Australia’s eastern abyss.

Pedicellaria and papulae of Asterias forbesi The body wall consists of a thin cuticle, an epidermis consisting of a single layer of cells, a thick dermis formed of connective tissue and a thin coelomic myoepithelial layer, which provides the longitudinal and circular musculature. The dermis contains an endoskeleton of calcium carbonate components known as ossicles. These are honeycombed structures composed of calcite microcrystals arranged in a lattice.
They remove debris from the body surface and wave around on flexible stalks in response to physical or chemical stimuli while continually making biting movements. They often form clusters surrounding spines. The edges of adjacent paxillae meet to form a false cuticle with a water cavity beneath in which the madreporite and delicate gill structures are protected. All the ossicles, including those projecting externally, are covered by the epidermal layer.
Some are thought to assist in defence, while others aid in feeding or in the removal of organisms attempting to settle on the starfish’s surface. These serve a respiratory function. This arrangement enables both easy flexion of the arms by the starfish and the rapid onset of stiffness and rigidity required for actions performed under stress. Water enters the system through the madreporite , a porous, often conspicuous, sieve-like ossicle on the aboral surface.
