The
Edge of the Sea of Cortez Tidewalker's Guide to the Upper Gulf of California by Betty Hupp and Marilyn Malone Operculum, 2009 |
|||
| A
pair of beachcombers, both mothers of curious children, created this colorful guide to the critters inhabiting the tide
pools of the Upper Gulf of California. No other comparable reference
was available to identify and explain the strange creatures slipping
under rocks or burrowing in the beach sand during their family
vacations. |

"The
Edge of the Sea of Cortez" is a marine biology guide for all ages,
packed with over 1,000 photographs and illustrations of shoreline
invertebrates arranged by their habitats -- rocky shores, sandy shores,
muddy flats and esteros. Brief descriptions accompany each creature
along with identification tips and advice on finding specimens.
The book includes maps, beachcombing tips, and identification
puzzles inside both covers. |
Slate Pencil Urchin
The slate pencile urchin is a rock borer and takes refuge in small cavities in the reef to protect itself from its enemies, mainly sea stars and triggerfish. It is a vegetarian browser that traps bits of algae in its spines and passes them around to its mouh. It also scrapes encrusting organisms off rocks and bites them into small bits with its five sharp teeth. |

'We
hope that you find the treasures of the sea as beautiful and as
fascinating as we do," the authors write. "We also hope that you enjoy
them in their natural environment, disturb them as little as possible,
and leave even empty shells where you find them. You never know when a
hermit crab will be looking for a new home." |
