I went through my science phase as a child and can easily relate to the fascination of Erasmus for discovering and collecting things. It is in fact the childlike enthusiasm of these early explorers that provides much of the energy of Barrett's historical fiction. a b c "The Biology and Ecology of Narwhals". noaa.gov.

During the voyage to these exotic outposts in Greenland and northern Canada, the story is about the tension between Zeke and his crew, with Erasmus caught in the middle. Erasmus is drawn to the surgeon, Dr. Boerhaave, himself an amateur natural historian, and the young Irish immigrant cook, Ned Lynd, who apparently was a minor character in Barrett's earlier Ship Fever, which won a National Book Award. In harrowing detail, drawing on numerous journals of real explorers from that period, Barrett depicts the hardships of the voyage and the privations and dangers that set in once they are immobilized for the long, dark winter. Narwhals can live up to 50 years [ inconsistent] and often die by suffocation after being trapped due to the formation of sea ice. Other causes of death, specifically among young whales, are starvation and predation by orcas. As previous estimates of the world narwhal population were below 50,000, narwhals are categorised by the International Union for Conservation of Nature (IUCN) as " nearly threatened". More recent estimates list higher populations (upwards of 170,000), thus lowering the status to " least concern". [4] Narwhals have been harvested for hundreds of years by Inuit in northern Canada and Greenland for meat and ivory and a regulated subsistence hunt continues.Wonderfully fun and perfectly pitched for bigger-topic conversations; the Narwhal and Jelly books are must-haves for your child’s collection.”— Children’s Book Review

but sometimes it's just about what you need at a particular time, and this book brought a goofy smile to my face when i really really needed it.Growing up in the ocean, Kelp has always assumed that he was a narwhal like the rest of his family. Sure, he’s always been a little bit different—his tusk isn’t as long, he’s not as good of a swimmer, and he really doesn’t enjoy the cuisine. Then one night, an extra strong current sweeps Kelp to the surface, where he spots a mysterious creature that looks just like him! Kelp discovers that he and the creature are actually unicorns. The revelation leaves him torn: is he a land narwhal or a sea unicorn? But perhaps, if Kelp is clever, he may find a way to have the best of both worlds. After posting this initially, I discovered some notes I made during the read, so I have done a bit of revision. 26/10/15 Overall, though? It felt, I think, like it needed one last round of polish. The early diary entries seemed stilted and mannered, all of them, no matter the diary keeper; the pace was sometimes ponderous, sometimes rushed, and the last section, as I said, was like a cascade of resolutions. Perhaps, after so many short stories, Ms. Barrett still felt the urge to tie every single thread, as neatly as possible--? For these voyages were primarily about ambition. Barrett is a master at portraying the passion that motivated these 19th-century scientists, discovering and cataloging nature in all its aspects, as she displayed in the collection of novellas in Servants of the Map. This was Erasmus's main motivation. He grew up in a Philadelphia household where his father -- much like Indiana Jones' father as portrayed by Sean Connery -- was obsessed with arcane learning and indoctrinated his children -- especially the four sons Erasmus, Linnaeus, Humboldt and Copernicus -- in his love of learning and discovery.

I failed quite a bit that day. I just couldn't get into the book. It was dry, it was confusing. Barrett added in little unexplained details that you knew would be explained later, but this is an affectation that bothers me quite a bit, as my memory, distracted as I am by my life, isn't as great as I would like.

Memoirs of the Geological Survey, Great Britain. 1891.The most conspicuous characteristic of the male narwhal is a single long tusk, which is in fact a canine tooth [19] [20] that projects from the left side of the upper jaw, through the lip and forms a left-handed helical spiral. The tusk grows throughout life, reaching a length of about 1.5 to 3.1m (4.9 to 10.2ft). It is hollow and weighs around 10kg (22lb). About one in 500 males has two tusks, occurring when the right canine also grows out through the lip. Only about 15 per cent of females grow a tusk, [21] which typically is smaller than a male tusk, with a less noticeable spiral. [22] [23] [24] There is only one known case of a female growing a second tusk; the specimen (right) was collected in 1684. [25] During growth, the narwhal accumulates metals in its internal organs. One study found that various metals are lightly concentrated in the blubber and densely concentrated in the liver and the kidneys. Zinc and cadmium are found in higher concentration in the kidney compared to the liver; the inverse is true for lead, copper and mercury. Certain metals were correlated with size and sex. During growth, it was found that mercury accumulated in the liver, kidney, musculature, and blubber, and cadmium also settled in the blubber.
