REPRESENTATIVE MARINE ARTHROPODS Order #455..........$42.50

A survey of marine arthropods with emphasis on the class Crustacea, orders
Isopoda, Stomatopoda and Decapoda. Covers characteristics that distinguish between
groups, general behavior, typical habitats, predator-prey relationships and other unusual
habits such as symbiotic relationships. Animals represented: isopods, mantis shrimps,
cleaner shrimps, commercial shrimps, spider crabs, commercial crabs, spiny lobsters
and pelagic red crabs. Many never before photographed alive. 20 slides and guide.

CONTENT SAMPLE: 21238 Another shrimp, the red back cleaner shrimp (Lysmata
grabhami) is even more specialized in its cleaning habits than L. californica. This tropical
species occurs throughout Indo-Pacific and Caribbean waters. Unlike the Panamic cleaner, it
sports a contrasting white stripe on its back extending the length of the body from the head
spine to the tail. This contrasting coloration is an important signal to parasitized fish, as it
advertises the shrimp as a facultative cleaner.

The phenomenon of contrasting colors characterized by striped patterns to advertise a
potential cleaner has also been reported among certain species of tropical fish, such as the
cleaner wrasse (Labroides sp.) of the Indo-Pacific, and Caribbean gobies (Gobiosoma spp.).
Like the red back cleaner shrimp, these fish display a striped pattern, but in a different color
scheme. They also act as benevolent “doctors” by removing bacteria and parasites from other
fish. There are over 40 species of fish and 15 species of shrimps in tropical seas recognized as
cleaners.

This kind of beneficial cleaning symbiosis is not restricted to marine animals: On land,
the red cleaner crab of the Galapagos removes tiny ticks from iguanas. In Africa some species
of birds pick ticks and mites from cattle, and several species of spiders are even known to assist
certain infested insects by removing minute parasitic mites.

As benevolent as they may appear, these cleaning relationships among animals are
guided by a simple motive--food.

REPRESENTATIVE MARINE MOLLUSCS Order #456..........$42.50

Features four classes of the phylum Mollusca: Gastropoda, Pelecypoda,
Cephalopoda and Amphineura. Includes detailed descriptions, development and
adaptation, predator-prey relationships, distribution, and other important, little-known
facts. Animals shown include living helmet shells, cowries, cone shells, olive shells,
nudibranchs, bivalves, octopuses and many others. Many never before photographed.
20 slides and guide.

CONTENT SAMPLE: 21286 Aeolidacean nudibranchs are equipped with plume-like
projections known as cerata. This beautiful Spanish shawl (Coryphella iodena) from the Gulf
of California has numerous colorful cerata covering its entire back.

However attractive they may be, cerata are not merely decorative appendages, but
awesome defensive devices, armed with tiny nematocysts. These stinging cells come from the
tentacles of their coelenterate prey. When ingested, the cells do not discharge, but move to the
tip of the cerata. When the cerata are disturbed by a predator, the nematocysts are released.

The nematocysts in some species are quite potent and can be dangerous to humans. A
potentially hazardous nudibranch is the beautiful, pelagic Glaucus atlanticus. An aeolidacean
nudibranch, it is circumtropical, always floating on the surface by trapping air bubbles in its
stomach. It preys primarily on the dangerous man-of-war (Physalia physalia). In the process, it
ingests the man-of-war’s stinging cells and retains them for its own defense. Only the largest
nematocysts are saved, the others are digested.

Bathers should avoid handling these aeolidacean nudibranchs with bare hands. Should
you be stung by a nudibranch or a man-of-war, one of the best treatments is to rub meat
tenderizer directly on the skin lesions. Nematocyst venom is a protein-based neurotoxin which
is broken down by the tenderizer.

represent the brilliant colors found among the animals in this phylum. Recommended." Previews.

INTRODUCTION TO SEASHELLS OF NORTH AMERICA Order #411..........$42.50

A survey of common and rare univalve and bivalve mollusc shells found along the
saltwater coasts of North America. The living animals, their range, habitats, morphology
and behavior are described. Emphasizes formation and growth of the shells, various
ways man has employed them throughout the ages--as money, in ornamentation, as
food containers--and the disappearance of many of the shellbearing molluscs due to
habitat destruction and predation by man. Species presented include queen, horse and
crown conch; abalone; olive; fig shell; banded tulip; cowry; whelk egg cases; tellin; heart
cockle; disk shell; pen shell; kitten's paws; clams; scallop and sand dollar. 20 slides
and guide.

REVIEWS: "A good inexpensive resource...text is detailed and informative." Bay Area

eye-opening program presents the transition from simple unicellular animals, to colonial forms, to
complex multicellular creatures.

An easy going, highly informative interactive narrative linked to a very extensive supplemental text
provides easily accessible, near encyclopedic information about every animal—right at the user’s
fingertips! Additional interactive features access over 50 questions with explanations, automatic
quizzes and a customized glossary.

The phylum Mollusca appears to consist of an odd assemblage of animals, yet all have the same
basic body plan. Next to the arthropods, molluscs are the most abundant species of
invertebrates. Estimates of the number of living species range up to 130,000. Because of their
great abundance and the durability of their shells, molluscs have always played a significant role
in human society, not only as food, but as tools and utensils, in ornaments and jewelry, in art,
mythology and religion, and even as currency.
