Koi Carp..
History
The carp is a large group of fish originally found in Central Europe and Asia. Various carp species were originally domesticated in East Asia, where they were used as food fish. The ability of carp to survive and adapt to many climates and water conditions allowed the domesticated species to be propagated to many new locations including Japan. Natural color mutations of these carp would have occurred across all populations. Carp were first bred for colour mutations in China more than a thousand years ago, where selective breeding of the Prussian carp (Carassius gibelio) led to the development of the goldfish.
Carp are known as koi in Japan. Of the various domesticated carp species, the common carp (Cyprinus carpio) is one of the more commonly used in aquaculture. Common carp were first introduced into Japan by way of China between 400 to 600 years ago. Common carp were first bred for color in Japan in the 1820s, initially in the town of Ojiya in the Niigata prefecture on the north eastern coast of Honshu island. By the 20th century, a number of colour patterns had been established, most notably the red-and-white Kohaku. The outside world was not aware of the development of colour variations in koi until 1914, when the Niigata koi were exhibited in the annual exposition in Tokyo. At that point, interest in koi exploded throughout Japan. The hobby of keeping koi eventually spread worldwide. Koi are now commonly sold in most pet stores, with higher-quality fish available from specialist dealers.
Extensive hybridization between different populations has muddled the historical zoogeography of the common carp. However, scientific consensus is that there are at least two subspecies of the common carp, one from Western Eurasia (Cyprinus carpio carpio) and another from East Asia (Cyprinus carpio haematopterus). One recent study on the mitochondrial DNA of various common carp indicate that koi are of the East Asian subspecies. However another recent study on the mitochondrial DNA of koi have found that koi are descended from multiple lineages of common carp from both Western Eurasian and East Asian varieties. This could be the result of koi being bred from a mix of East Asian and Western Eurasian carp varieties, or koi being bred exclusively from East Asian varieties and being subsequently hybridized with Western Eurasian varieties (the butterfly koi is one known product of such a cross). Which is true has not been resolved.
Etymology
The word 'koi' comes from Japanese, simply meaning "carp." It includes both the dull grey fish and the brightly coloured varieties. What are known as 'koi' in English are referred to more specifically as 'nishikigoi' in Japan (literally meaning 'brocaded carp'). In Japanese, 'koi' is a homophone for another word that means 'affection or love'; koi are therefore symbols of love and friendship in Japan. An example of this is given in a short story by Mukoda Kuniko, "Koi-san". Koi tattoos have also become a popular trend in North America.

I was disappointed with this one, not getting it all in, but it was a one take gamble lol.
The Grey Seal (Halichoerus grypus) is found on both shores of the North Atlantic Ocean. It is a large seal of the family Phocidae or "true seals". It is the only species classified in the genus Halichoerus. Its name is alternatively spelled Gray Seal and it is also known as Atlantic Grey Seal.
Appearance
It is a medium sized seal, with the bulls reaching 2.5 -- 3.3 m long and weighing up to 300 kg; the cows are much smaller, typically 1.6--2.0 m long and 100--150 kg weight. It is the typical seal of the northern and western coasts, the Common Seal being more often seen off southeastern coasts.
Ecology
In Britain and Ireland, the Grey Seal breeds in several colonies on and around the coasts; notably large colonies are at the Farne Islands off the Northumberland Coast (about 6,000 animals), and North Rona off the north coast of Scotland and Lambay Island off the coast of Dublin.
In the Western North Atlantic, Grey Seals are typically found in large numbers all along the coast of North America up to about the coastal waters of New Jersey in the United States. In Canada, they are typically seen in areas like the Gulf of St. Lawrence, Newfoundland and the Maritimes, and Quebec. In the United States one finds them year round off the New England coasts (in particular Maine and Massachusetts) and slightly less frequently in the Middle Atlantic States, though their natural range extends to Virginia. During the winter months they can be seen hauled out on the rocks, islands, and shoals not far from shore, like great grey bananas in the sun, and occasionally coming ashore to rest. In the spring the recently weaned pups and yearlings occasionally strand on beaches after becoming "lost".
Diet
Grey seals feed on a wide variety of fish, mostly benthic or demersal species, taken at depths down to 70m (230ft) or more. Sandeels (Ammodytes spp) are important in their diet in many localities. Cod and other gadids, flatfish, herring and skates are also important locally. However, it is clear that Grey seals will eat whatever is available, including octopus and lobsters. The average daily food requirement is estimated to be 5kg (11lb), though the seals do not feed every day and they fast the breeding season.
Reproduction
The pups are born in autumn (September to November) in the eastern Atlantic and in winter (January to February) in the west, with a dense, soft silky white fur; at first they are small and shrivelled-looking, but they rapidly fatten up to look like over-filled barrels, from the extremely fat-rich milk they receive from their mothers. Within a month or so, they shed the pup fur and grow the dense waterproof adult fur, and soon leave for the sea to learn to fish for themselves. In recent years, the number of grey seals has been on the rise in the west, and in Canada there have been calls for a seal cull, however this does not appear to be coming to fruition any time soon.
Status
In the United States grey seal numbers are increasing as well; they have been protected under the Marine Mammal Protection Act for several years and it is still illegal to harm one. Before the act there were only a few isolated colonies in Maine and nowhere else. Today they are seen increasingly near New York and New Jersey waters and it is very likely they will establish colonies further and further south provided the main Canadian pupping grounds are not molested. It is also not very likely a seal hunt shall be instituted any time soon in the U.S.
In the UK seals are protected under the Conservation of Seals Act 1970, however it does not apply to Northern Ireland. In the UK there have also been calls for a cull from some fishermen, claiming that stocks have declined due to the seals. A recent paper, however, from the Sea Mammal Research Unit at St Andrews University ( www.smru.st-and.ac.uk ) clarifies that seals take less than 1% of the total stock biomass in the North Sea. The real problem is over fishing.

An extra note......
The seal sanctuaries do an excellent job in rescuing injured seals, making them better ,then returning them to the sea. This one was seen in the Skegness Sanctuary, well worth a visit, if you are on the east coast, Lincolnshire.
