Abstract Background: Among metazoans, retention of functional diet-derived chloroplasts (kleptoplasty) is known only from the sea slug taxon Sacoglossa (Gastropoda: Opisthobranchia). Intracellular maintenance of plastids in the slug's digestive epithelium has long attracted interest given its implications for understanding the evolution of endosymbiosis. However, photosynthetic ability varies widely among sacoglossans; some species have no plastid retention while others survive for months solely on photosynthesis. We present a molecular phylogenetic hypothesis for the Sacoglossa and a survey of kleptoplasty from representatives of all major clades. We sought to quantify variation in photosynthetic ability among lineages, identify phylogenetic origins of plastid retention, and assess whether kleptoplasty was a key character in the radiation of the Sacoglossa. -

South Carolina Department of Natural Resources
FOREWORD Abundant fish and wildlife, unbroken coastal vistas, miles of scenic rivers, swamps and mountains open to exploration, and well-tended forests and fields…these resources enhance the quality of life that makes South Carolina a place people want to call home. We know our state’s natural resources are a primary reason that individuals and businesses choose to locate here. They are drawn to the high quality natural resources that South Carolinians love and appreciate. The quality of our state’s natural resources is no accident. It is the result of hard work and sound stewardship on the part of many citizens and agencies. The 20th century brought many changes to South Carolina; some of these changes had devastating results to the land. However, people rose to the challenge of restoring our resources. Over the past several decades, deer, wood duck and wild turkey populations have been restored, striped bass populations have recovered, the bald eagle has returned and more than half a million acres of wildlife habitat has been conserved. We in South Carolina are particularly proud of our accomplishments as we prepare to celebrate, in 2006, the 100th anniversary of game and fish law enforcement and management by the state of South Carolina. Since its inception, the South Carolina Department of Natural Resources (SCDNR) has undergone several reorganizations and name changes; however, more has changed in this state than the department’s name. According to the US Census Bureau, the South Carolina’s population has almost doubled since 1950 and the majority of our citizens now live in urban areas. -

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.

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.
