Book Review: Sea Mammals

Published

Sea Mammals: The Past and Present Lives of Our Oceans’ Cornerstone Species by Annalisa Berta

This is a book packed with information about some of the most iconic and charismatic marine species. I have a particular soft spot for the pinnipeds, seals and sea lions, due to some incredible diving encounters over the years. So these were the pages I first turned to.

Once picked up this book is hard to put down. Polar Bears, Narwhal, Sea Otters, manatees, whales and dolphins adorn the pages with beautiful photographs and illustrations. Each turn of the page lures you in to discover more about a species you love, one you want to learn more about, some you have never heard of and even includes the details of fascinating animals that are sadly now extinct.

I think what I love most about this book is how it is organised. Rather than simply lump the animals into taxonomic groupings, they are put into chapters that tell you a story about them. Whether it is the story of their evolution, how they were discovered, their biology, behaviour or need for conservation. Once you have decided on an animal to delve deeper into, each species has its own story, as well as key information about size, diet, distribution, habitat and conservation status.

There is plenty to enjoy in this delightful book. Plenty to learn too. As the cold dark nights draw in, I can see myself delving into this book time and time again. This is a perfect gift for anyone that loves the ocean and its inhabitants. Or just treat yourself.

What the publisher says:

From the gregarious sea otter and playful dolphins to the sociable narwhal and iconic polar bear, sea mammals are a large, diverse, and increasingly precious group. In this book, Annalisa Berta, a leading expert on sea mammals and their evolution, presents an engaging and richly illustrated introduction to past and present species of these remarkable creatures, from the blue whale and the northern fur seal to the extinct giant sperm whale, aquatic sloth, and walking sea cow.

The book features more than 50 individual species profiles, themed chapters, stunning photographs, and specially commissioned paleo-illustrations of extinct species. It presents detailed accounts of these mammals’ evolutionary path, anatomy, behavior, habitats, and conservation. And because these are key species that complete many food chains and have the widest influence of all sea life, the book also offers insights into a broad variety of marine worlds today and in the future.

About the Author:

Annalisa Berta is professor emerita of biology at San Diego State University. A specialist in the anatomy and evolutionary biology of marine mammals, especially baleen whales, she formally described a skeleton of the early pinniped Enaliarctos. She is the author of Return to the Sea: The Life and Evolutionary Times of Marine Mammals and the editor of the award-winning Whales, Dolphins, and Porpoises: A Natural History and Species Guide.

Save the Manatee Club launches brand new webcams at Silver Springs State Park, Florida

Published

Save the Manatee® Club has launched a brand-new set of underwater and above-water webcams at Silver Springs State Park in Ocala, FL. These new cameras add to our existing cameras at Blue Spring State Park in Orange City, Florida, and Ellie Schiller Homosassa Springs Wildlife State Park, in Homosassa, Florida, which are viewed by millions of people worldwide. The cameras are a collaboration between Save the Manatee Club, Explore.org, and the Florida Department of Environmental Protection, who made the new live streaming collaboration possible via support of their interpretative program.

The above-water camera is a stationary pan/tilt/zoom camera that will show manatees and other wildlife from above water, while the new underwater camera provides the viewer with a brand new, exciting 180-degree viewing experience. Viewers can move the cameras around, trying to spot various fish and manatees.

The Silver River, which originates at Silver Springs, provides important habitat for manatees and many other species of wildlife. Over recent years, more manatees have been seen utilizing the Silver and Ocklawaha rivers. “The webcams provide a wonderful entertainment and educational tool to the general public, but they also help us with the manatee research,” says Patrick Rose, Executive Director of Save the Manatee Club. “We have learned so much through observing manatees on our existing webcams, and the new cameras at Silver Spring can add to the existing manatee photo-ID research conducted in this area, as well as highlighting Silver Springs and the Silver River as an important natural habitat for manatees.”

The webcams are streaming live during the daytime, with highlights playing at night, and can be viewed on Explore.org and on Save the Manatee Club’s website at ManaTV.org.

Save the Manatee Club, established in 1981 by the late renowned singer-songwriter, author, and entrepreneur Jimmy Buffett, along with former Florida Governor and U.S. Senator Bob Graham, is dedicated to safeguarding manatees and preserving their aquatic habitat. For more information about manatees and the Club’s efforts, visit savethemanatee.org or call 1-800-432-JOIN (5646).

Stranded dolphin rescued from muddy inlet

Published

dolphin

At around 11:40 on Friday 16 February, a lone common dolphin was reported to British Divers Marine Life Rescue circling in the shallows in an inlet at Place, near Portscatho, in Cornwall. A couple of volunteer Marine Mammal Medics were sent down initially to monitor the animal in hope it would be able to get away by itself, and further assess the situation.

After an hour and a half or so of observation, the risk of stranding increased significantly as the tide went out as the inlet is very shallow, muddy and almost completely dries out over low tide. Therefore, a larger response team was dispatched with more equipment in preparation for a stranding. Indeed, the animal did soon strand in the mud and fell onto its side, submerging the blowhole. Luckily the team were on hand to help get it upright again quickly, then bring it ashore for a health assessment and to begin providing first aid. No obvious injuries could be found and it measured 2.03m, later confirmed as female.

The team were soon joined by two vets, who were able to confirm the animal to be in moderate nutritional condition and appeared otherwise okay following a more detailed health check, and so was suitable for the team to attempt to refloat. However, it was not possible to refloat it safely in the inlet due to the nature of the geography, substrate and tide there it seemed the most likely reason this dolphin had stranded was due to getting disoriented in this location, and would struggle to get out again. Luckily a local resident had his boat tender moored nearby and was happy to use it a transport craft to take the dolphin out to deeper water.

With help, the boat was slid across the mud and launched near the mouth of the inlet. A surfboard was placed on one side with a soft mat on top for the dolphin to lie comfortably on during the journey. When ready, the dolphin was carried across in a tarpaulin, transferred to a mesh stretcher and loaded on board with a team of four Medics including a vet.

The boat then carefully made its way out to the mouth of the Percuil River, facing into Carrick Roads and close to open sea, which was the most ideal site for release where the chance of returning and re-dolphinstranding was lower. The dolphin was carefully hauled overboard in the stretcher and held alongside briefly, though as she started kicking strongly almost straight away it was hard to keep hold and so she was released quickly. The boat retreated and the team observed her circling in the middle of the channel until she was lost from sight. The team returned to the inlet before darkness fell.

The area will be monitored over the weekend for re-sightings or re-strandings, but it is hoped that she will recover successfully and continue back out to sea. In the meantime BDMLR would like to thank the volunteer team, local residents and members of the public for all their efforts and support throughout this incident.

British Divers Marine Life Rescue is an international marine animal rescue organisation based in the UK and is a registered charity.  The aims of the organisation are to provide a rescue service for marine wildlife, to support existing rehabilitation centres and to develop new methods of rescue, treatment, transport and care.  Website www.bdmlr.org.uk.
