When people hear the word “migration,” they think of animals that move from a feeding area to a breeding area and back each year. But the greatest migration on Earth happens twice every night. The movement is largely vertical and performed by plankton followed by predatory fish, squid, octopus and other species that have acquired a taste for plankton. The migration starts deep in the waters of the ocean at sunset. As they move, the plankton nibble on plant plankton and other tasty morsels in the water and, eventually, some on each other. The feeding ends just before dawn when the plankton retreat to the depths of the ocean to hide during the day until the next evening, when they migrate back up the water column. In Planktonia, Erich Hoyt invites readers to dive into the dazzling nighttime ocean. Countless microscopic plankton — larval creatures such as ornate ghost pipefish, left-handed hermit crabs and bony-eared assfish — ascend to the upper waters to feed, returning to the depths before sunrise. These tiny planktonic creatures are delicate and beautiful; some look terrifying; and most look nothing like the creatures they will become as adults. This great vertical migration attracts larger adult creatures, too, from the solitary 6-inch (15 cm) bigfin reef squid and the fierce and hungry 6½ foot (2 m) female blanket octopus, which is up to 40,000 times heavier than her male mate. Everyone comes here for the midnight feast, and they are all ravenously hungry. Chapters in this book include: Hawai’i: From Bluewater to Blackwater; Awesome Anilao; The Gulf Stream Procession of Life; Blackwater White Sea; Precious Life of Plankton; Blackwater Unlimited; From Blackwater Passion to Protection. All life in the ocean depends on plankton. Plankton plays a key role in sequestering carbon against climate change. The great nightly vertical migration highlights the importance of protecting not only ocean species but also ecosystems that embrace ocean processes from the depths of the sea to surface waters.

A timely update on a beloved classic. When Erich Hoyt’s Orca: The Whale Called Killer was first published in 1981, little was known about Orcinus orca. The largest member of the dolphin family was then considered too dangerous to approach in the wild. That all changed when Erich Hoyt and his colleagues spent seven summers in the 1970s following these intelligent, playful creatures in the waters off northern Vancouver Island. Working alongside other researchers keen to understand the life history of the killer whale, Hoyt’s group helped to dispel the negative mythology about orcas while uncovering the intimate details of their social behaviour. This revised fifth edition includes Hoyt’s original account, plus exciting new chapters that bring readers up to date on the revolution in public awareness and orca research that has taken place. Hoyt’s youthful adventures turned into his life’s work. Now a world-renowned expert on whales and dolphins, he shares orca wisdom along with stories gleaned from decades of additional field study in the Russian Far East as well as return trips to Canada’s West Coast to visit with the descendants of the killer whales he encountered 45 years ago.
