Big Pacific: All About The Great White Shark

From page 14-17 of Big Pacific:

Peripatetic pilgrims of the Pacific, Great white sharks have one of the widest geographic ranges of any marine animal. Individuals migrate vast distances — even across entire ocean basins — and in the Pacific they can be found as far north as Alaska and as far south as New Zealand’s Sub-Antarctic Islands. Every year, however, a great many of these oceanic travelers congregate around La Isla Guadalupe (Guadalupe Island), 241 kilometers (150 miles) off the western coast of Mexico. First to arrive, in spring and summer, are males. The females — who generally dwarf the males — arrive in the fall. It’s thought mating occurs in the late fall, although no one has ever witnessed great whites in the act. Pregnant females spend a year or more at sea while as many as ten embryos develop inside their bodies. At birth the pups measure around a meter (3 to 4 feet). Like their parents, these youngsters disappear into the deep blue, perhaps using their remarkable ability to read the magnetic fields of the Earth’s crust to navigate their way across the ocean.

The Great White Shark. With little obvious differentiation other than the size disparity, it can be tricky to distinguish between male and female Great whites.

Unsurprisingly for such a highly evolved predator, Great white sharks are endowed with keen sensory organs. Their sense of smell — which enables them to detect a single drop of blood in 10 billion drops of water — is legendary and helps give rise to their fearsome reputation as hunters. But their vision is also good: the retina of a Great white’s eye is dually adapted for day vision and low light. Even more impressive is their ability to detect electrical currents through pores on their snouts which are filled with cells called the ampullae of Lorenzini.

Big Pacific: Passionate, Voracious, Mysterious, Violent
By Rebecca Tansley

The Pacific Ocean covers one-third of Earth’s surface—more than all of the planet’s landmasses combined. It contains half of the world’s water, hides its deepest places, and is home to some of the most dazzling creatures known to science. The companion book to the spectacular five-part series on PBS produced by Natural History New Zealand, Big Pacific breaks the boundaries between land and sea to present the Pacific Ocean and its inhabitants as you have never seen them before.

Illustrated in full color throughout, Big Pacific blends a wealth of stunning Ultra HD images with spellbinding storytelling to take you into a realm teeming with exotic life rarely witnessed up close—until now. The book is divided into four sections, each one focusing on an aspect of the Pacific. “Passionate Pacific” looks at the private lives of sea creatures, with topics ranging from the mating behaviors of great white sharks to the monogamy of wolf eels, while “Voracious Pacific” covers hunting and feeding. In “Mysterious Pacific,” you will be introduced to the Pacific’s more extraordinary creatures, like the pufferfish and firefly squid, and explore some of the region’s eerier locales, like the turtle tombs of Borneo and the skull caves of Papua New Guinea. “Violent Pacific” examines the effects of events like natural disasters on the development of the Pacific Ocean’s geography and the evolution of its marine life.

Providing an unparalleled look at a diverse range of species, locations, and natural phenomena, Big Pacific is truly an epic excursion to one of the world’s last great frontiers.

Join us from February 3 – 8 as we celebrate UnShark Week

What is UnShark Week, you ask?

A birthday held six months away from the real one, is an UnBirthday. So, for the thousands of ocean species that are just as interesting and sometimes more extreme than sharks, we propose the week of Feb 3-8, 2014 as UnSharkWeek.

UnSharkWeek will introduce fans of Shark Week to other extreme forms of life in the sea. There are all sorts of really cool things happening in the harshest environments on Earth, so join Steve Palumbi, one of the world’s leading marine biologists, as he celebrates some of the deepest, fastest, oldest, and just plain strangest creatures found in the ocean.
