WHALES AND DOLPHINS Order #489........$42.50

Richard Ellis's magnificent paintings of these inspiring creatures, often painted
from first hand knowledge gained diving among them, have won worldwide acclaim. Made
famous by their publication in magazines and books, this series presents his paintings
of 20 different cetacean species. Accompanying text summarizes present knowledge.
20 slides and guide.

CONTENT SAMPLE: 26861 The arctic bowhead whale (Balaena mystecitus), seen
here with a pair of belugas, is a thickset baleen whale much given to making spectacular leaps
out of the water. It can reach 19 m (65 ft.) in length--as much as one third of which may be head.
The bowhead’s tongue alone can weigh as much as a ton. This species is also known as a “right”
whale, because it was one of the easy whales to kill.

In addition to its oil, bowheads were much sought after for their baleen--a flexible,
keratinous substance similar to fingernails that was widely used for corset stays, umbrella ribs,
fishing rods and buggy whips. A single whale could yield a ton of baleen, and the 500 to 600
plates, if laid end to end, could stretch a mile.

Female bowheads are said to be extremely protective of their calves, standing by injured
young, or charging boats when they are threatened. Nevertheless the bowhead, also known as
the great Polar whale, Arctic right whale, and Greenland right whale, is now officially listed as an
endangered species. Once plentiful in all Arctic waters, the bowhead whale was virtually
exterminated throughout most of its range. For perhaps half a century now, the whale has been
left in peace, in hopes that it may rebuild its decimated numbers. The last of the bowhead
whales inhabit the high northern Arctic, where only Eskimos hunt them.

REVIEW: “...meticulously accurate yet dramatic...will entrance viewers of any
age. The printed material is not only informative, but stylistically graceful and even moving.... A
superior slide-set in every way. Recommended for purchase without reservation.” Media Review.

BIOLOGY OF WHALES Order #SS-1015S........$42.50

This study of a unique group of marine mammals includes taxonomy,
adaptations, locomotion, skeletal structures, endothermy, feeding habits, sounding
and the outlook for the future. A must for all whale enthusiasts. 21 frames and guide.
(Filmstrip order SS-1015F.....$15.00.)

CONTENT SAMPLE: 15. The baleen whales are subdivided into three families;
Balaenopteridae, Balaenidae and Escherichtidae. Those in the family Balaenopteridae are also
called the rorquals or fin-backed whales. They are represented by the blue whale (Balaenoptera
musculus), the fin whale (Balaenoptera physalus), the sei whale (Balaenoptera borealis), and the
humpback whales, of which there are five species. The family name “rorqual” is derived from the
Norwegian word for “tubed whale” describing the pleat-like, ventral grooves on their throats. These
grooves allow the mouth to be distended, thereby increasing the volume of sea water that can be
filtered. Rorquals have comparatively slender bodies with distinctive dorsal fins and small flippers.
The humpback is distinguished by enormous flippers that are nearly one-third of its body length.
Humpback whales survive in three distinct populations; the North Atlantic, the North Pacific, and
the Southern Hemisphere. They are considered to be the most athletic of whales and are known
among cetologists for their high leaps out of the water and occasional mid-air somersaults, called
breaches. Humpbacks are also the whales that have been extensively recorded and whose
ethereal “songs” are commercially available on records.

The right whales are in the family Balaenidae. The right whales were so named because
they were just “right” for nineteenth century whalers to pursue; they were slow, their carcasses
floated, and they yielded above average quantities of oil. As a result, the world’s populations of
right whales have been decimated by centuries of extensive hunting.

MARINE MAMMALS Order #SS-1060S......$49.95

Focuses on mammals that have successfully adapted to the oceans over the
ages. Marine mammals, like other terrestrial vertebrates adapted to aquatic living,
breathe air. So they must all exchange respiratory gases with the atmosphere. Several
marine mammals are compared with their terrestrial relatives. 19 frames, cassette and
guide, slides or filmstrip.

CONTENT SAMPLE: 1. Mammals have invaded the ocean several different times
and the different groups show various degrees of adaptation to an aquatic or semiaquatic
existence. Like the other terrestrial vertebrates that have adapted to aquatic life, the marine
mammals are air breathers. All must consequently retain a link with the surface, periodically
rising to exchange respiratory gases with the atmosphere. None of the marine mammals have
the freedom of the fishes, but some have developed fish-like forms. A fusiform (spindle shaped)
body enhances mobility in the relatively dense aquatic medium. Fins, flippers and flukes all
exhibit a common shape that is more efficient for moving through water. These similarities of
form are examples of convergent evolution; they serve analogous functions but have arisen in
groups of different ancestry. Despite the development of externally apparent adaptations to
marine life, the marine mammals are characterized by fundamentally the same organ systems
as their terrestrial relatives.

THE BEAVER'S WORLD Order #477..........$42.50

Follows these large rodents through such seasonal activities as tree felling, dam
and lodge construction and breeding. Examines such physical characteristics and
adaptations as teeth, tails, feet, lung capacity, food preferences, modes of com-
munication, sensory capabilities, and family structure. Reviews the environmental
impact of their tree cutting and dam building. 20 slides and guide.

CONTENT SAMPLE: 22031 Despite the obvious conservation benefits beaver provide, it
is only fair to acknowledge that as their numbers increased in the mid-1900's, so did the
complaints about their destructive activities. To this day their presence in an area is marked
by controversy--to many people this persistent rodent is a definite nuisance.

Because they reproduce prolifically, beavers are constantly searching out new territories
in which to build dams and create swamps, bringing them into direct conflict with man. In many
areas their dam building activities have repeatedly flooded valuable agricultural crops (top),
highways, railroads, bridges, septic systems and valuable forest areas. Their dams have also
blocked the routes of migrating fish and their need to stop water from flowing has motivated them
to plug many a culvert pipe.

Not only do beavers cause flooding, but their need to constantly gnaw on wood has led
to the destruction of wooden bridges, forest and fruit tree plantations and an occasional
ornamental planting. The beaver in the bottom portion of this slide actually occupied a
boathouse and started building a lodge, after gnawing on the wood partitions and floor. Regular
interruptions in its daytime siestas eventually persuaded it to locate elsewhere.

REVIEWS: “...fine set.... Superior slides are augmented by a text that can be used
in the middle grades as well as in high school...good resources in schools and public libraries.”
Booklist.

WATER ANIMALS Order #413..........$42.50

Portrays lifestyles of warm-blooded, air breathing mammals that live entirely in
the water, and mammals depending on aquatic foods but living on the land. Emphasis is
on the specialized evolutionary adaptations that equip these animals for survival in
aquatic environments. Includes polar bear, moose, lechwe, nutria, capybara, water vole,
beaver, otter, hippopotamus, sea lions, gray seals, walrus, manatee, porpoise, killer
whale, beluga whale and human diver. 20 slides and guide.

CONTENT SAMPLE: 294 This water mammal is the largest of the rodent family
and grows up to four feet long and to 100 pounds in weight. The capybara, or water pig, is native
to South America and is primarily aquatic. It lives in lakes, rivers and marshes, yet occasionally
spends time on land grazing much like a horse or cow. The diet of capybaras is almost exclu-
sively plant material, which is eaten in huge quantities. Generally they are found in family groups
of up to 20 and are timid and shy. In captivity, however, they tame readily and become quite
affectionate toward their keeper and visitors. In the wild capybaras are often hunted for food
(or because they are considered pests) by natives using dogs. They are chased into the water
and followed by men in canoes who kill them when they come up for air.

REVIEWS: “We are charmed by the slides of ocean mammals.... The reading
material is also of great interest...” A.H., Friends of Animals, Inc.

CONTENT SAMPLE:

11. Here we see a manatee breathing at the surface of the water. When manatees are
swimming, playing, or eating, they usually come to the surface and breathe every three or four
minutes. When they are resting, they can stay underwater for over twenty minutes.

12. Manatees have two nostrils at the end of their noses. The arrows in this picture
point to the manatee’s nostrils, which are used for breathing. When manatees are underwater,
small flaps cover their nostrils and keep water out of them.
