THE NAUTILUS [Vol
2 2 THE NAUTILUS [Vol. 69 (1) separated from each other by five centimeters. The snail was expanded with its head oriented away from the clam. When placed on the sand, the clam showed no activity during the next 30 minutes after which observations were discontinued. All but the lower (anterior) end of the body of the clam was covered by an envelope of slime secreted by the foot of the snail. It seems clear that P. duplicatus capturesEnsis directus by approaching it below the surface of the substratum and by ir ritating the lower portion so that it retreats upward. The snail then coats the razor clam with an envelope of slime which ap pears to have anesthetic properties. Successful capture proba bly depends on the ability of the snail to maintain contact with its prey until anesthesia takes place. ON THE OCCURRENCE OF THE NUDIBRANCH ALDERIA MODESTA (LOVÉN, 1844) ON THE CENTRAL CALIFORNIAN COAST By CADET HAND and JOAN STEINBERG Department of Zoology, University of California, Berkeley Alderia modesta (Loven, 1844) has long been known from the coasts of northern Europe. It has been recorded from as far north as the Trondheim Fjord in Norway (Norman, 1893), south to Skibbereen in Ireland (Allman, 1845) and on the French coast (Gollien, 1929). Therefore, it has been of con siderable interest to us to find well-established populations of an Alderia in two localities on the central Californian coast. Through the kindness of Monsieur G. Van Put of the Royal Institute of Natural Sciences of Belgium in Brussels and Dr. -

Abstract New stratigraphic evidence from the Cascadia margin demonstrates that 13 earthquakes ruptured the margin from Vancouver Island to at least the California border following the catastrophic eruption of Mount Mazama. These 13 events have occurred with an average repeat time of ¾ 600 years since the first post-Mazama event ¾ 7500 years ago. -
8 Armed Bandits; a Closer Look at Cephalopods an Educator’S Guide to the Program
8 Armed Bandits; A Closer Look at Cephalopods An Educator’s Guide to the Program Grades K-5 Program Description: This program explores the class of mollusk known as cephalopods. Cephalopods are the most intelligent group of mollusk and most of them lack a shell. The name cephalopod means “head-foot” and contains: octopus, squid, cuttlefish and nautilus. The goal of 8-armed bandits is to teach students the characteristics, defense mechanisms, and extreme intelligence of cephalopods. *Before your class visits the Oklahoma Aquarium* This guide contains information and activities for you to use both before and after your visit to the Oklahoma Aquarium. You may want to read stories about cephalopods and their abilities to the students, present information in class, or utilize some of the activities from this booklet. 1 Table of Contents 8 armed bandits abstract 3 Educator Information 4 Vocabulary 5 Internet resources and books 6 PASS/OK Science standards 7-8 Accompanying Activities Build Your Own squid (K-5) 9 How do Squid Defend Themselves?

Rhode Island's Shellfish Heritage
RHODE ISLAND’S SHELLFISH HERITAGE RHODE ISLAND’S SHELLFISH HERITAGE An Ecological History The shellfish in Narragansett Bay and Rhode Island’s salt ponds have pro- vided humans with sustenance for over 2,000 years. Over time, shellfi sh have gained cultural significance, with their harvest becoming a family tradition and their shells ofered as tokens of appreciation and represent- ed as works of art. This book delves into the history of Rhode Island’s iconic oysters, qua- hogs, and all the well-known and lesser-known species in between. It of ers the perspectives of those who catch, grow, and sell shellfi sh, as well as of those who produce wampum, sculpture, and books with shell- fi sh"—"particularly quahogs"—"as their medium or inspiration. Rhode Island’s Shellfish Heritage: An Ecological History, written by Sarah Schumann (herself a razor clam harvester), grew out of the 2014 R.I. Shell- fi sh Management Plan, which was the first such plan created for the state under the auspices of the R.I. Department of Environmental Management and the R.I. Coastal Resources Management Council.

Identifikasi Gambar Hewan Moluska Dalam Media Cetak Dua Dimensi
Jurnal Moluska Indonesia, April 2021 Vol 5(1):25 -33 ISSN : 2087-8532 Identifikasi Gambar Hewan Moluska Dalam Media Cetak Dua Dimensi (Identification of Molluscan Animal Image in Two-Dimensional Print Media) Nova Mujiono*, Alfiah, Riena Prihandini, Pramono Hery Santoso Pusat Penelitian Biologi LIPI, Cibinong, 16911, Indonesia. *Corresponding authors: [email protected], Telp: 021-8765056 Diterima: 7 Februari 2021 Revisi :16 Februari 2021 Disetujui: 14 Maret 2021 ABSTRACT Humans have known mollusks for a long time. The diverse and unique shell shapes are interesting to draw. The easiest medium to describe the shape of a mollusk is in two dimensions. This study aims to identify various images of mollusks in two-dimensional print media such as cloth, paper and plates. Based on the 10 sources of photos analyzed, 56 species of mollusks from 38 families were identified. The Gastropod class dominates with 45 species from 31 families, followed by Bivalves with 7 species from 5 families, then Cephalopods with 4 species from 2 families. Some of the problems found are the shape and proportion of images that different with specimens, some inverted or cropped images, different direction of rotation of the shells with specimens, and different colour patterns with specimens. Biological and distributional aspects of several families will be discussed briefly in this paper.

Molluscs: Bivalvia Laura A
I Molluscs: Bivalvia Laura A. Brink The bivalves (also known as lamellibranchs or pelecypods) include such groups as the clams, mussels, scallops, and oysters. The class Bivalvia is one of the largest groups of invertebrates on the Pacific Northwest coast, with well over 150 species encompassing nine orders and 42 families (Table 1).Despite the fact that this class of mollusc is well represented in the Pacific Northwest, the larvae of only a few species have been identified and described in the scientific literature. The larvae of only 15 of the more common bivalves are described in this chapter. Six of these are introductions from the East Coast. There has been quite a bit of work aimed at rearing West Coast bivalve larvae in the lab, but this has lead to few larval descriptions. Reproduction and Development Most marine bivalves, like many marine invertebrates, are broadcast spawners (e.g., Crassostrea gigas, Macoma balthica, and Mya arenaria,); the males expel sperm into the seawater while females expel their eggs (Fig. 1).Fertilization of an egg by a sperm occurs within the water column. In some species, fertilization occurs within the female, with the zygotes then text continues on page 134 Fig. I.
