Caribbean Wildlife Undersea 2017
Caribbean Wildlife Undersea life This document is a compilation of wildlife pictures from The Caribbean, taken from holidays and cruise visits. Species identification can be frustratingly difficult and our conclusions must be checked via whatever other resources are available. We hope this publication may help others having similar problems. While every effort has been taken to ensure the accuracy of the information in this document, the authors cannot be held re- sponsible for any errors.

National Park Service U.S. Department of the Interior Kalaupapa National Historical Park Hawaii Project to Repair the Kalaupapa Dock Structures Environmental Assessment August 2010 EXECUTIVE SUMMARY The Kalaupapa Settlement is home to surviving Hansen's disease (leprosy) patients, and is cur- rently managed jointly by the Hawaii Department of Health and the National Park Service (NPS). The vast majority of materials needed to sustain the park and the Kalaupapa Settlement is received by barge delivery. An engineering study (Daly 2005) has determined that severe win- ter swell conditions have compromised the structural integrity of the Kalaupapa harbor facilities used by the barge. The NPS proposes to ensure delivery of supplies essential to operate and maintain Kalaupapa National Historical Park (“the park”) and the community by improving conditions of the dock structures at the harbor. This environmental assessment considered two alternatives for improving conditions of the dock structures: Alternative A: The No Action Alternative: Current NPS management operations at the dock and harbor would remain unchanged without repair to the dock structures. The integrity and stability of the pier may be compromised to the point of being unsafe for barge operations. Over the long-term, barge service to the park would likely be disrupted or become sporadic. Delive- ries of annual supplies and materials used for state operations, park programs, and the park’s ongoing rehabilitation of historic properties would be affected. Alternative B: The Preferred Alternative: This alternative would include completion of the repairs necessary to maintain service via a small barge. Voids in the bulkhead wall toe, the low dock toe, and the breakwater would be filled for structural integrity, and repairs would be made to the pier dock. -

B. HOLTHUIS Rijksmuseum van Natuurlijke Historie, Leiden, Netherlands A. J. EDWARDS and H. R. LUBBOCK Department of Zoology, University of Cambridge, Cambridge, U.K. With two text-figures and one plate INTRODUCTION Saint Paul's Rocks (Penedos de Sao Pedro e Sao Paulo) are a small group of rocky islets on the mid-Atlantic ridge near the equator, occupying an area of roughly 250 by 425 m. There is no vegetation and, apart from birds and invertebrates, the islands are uninhabited. The Cambridge Expedi tion to Saint Paul's Rocks visited the group from 16 to 24 September 1979 and made extensive collections of the terrestrial and marine fauna; these included a number of Crustacea. The Decapoda and Stomatopoda of St Paul's Rocks are the subject of the present paper. Few detailed studies have been published to date on the Crustacea of St Paul's Rocks, largely because of the Rocks' remoteness and inhospitable nature. Crustacea, especially the common and conspicuous rock crab Grapsus grapsus, have been mentioned in several narratives and popular accounts, but the only material on which scientific reports have been based is that collected by H.M.S. "Challenger" in 1873. The Challenger reports mention eight species of Decapoda (5 Macrura, 1 Anomuran and 2 Brachyura) from St Paul's Rocks. The Cambridge Expedition collected nine species of Deca poda (2 Macrura and 7 Brachyura) and one species of Stomatopoda; in addition one macrurous decapod was observed but not collected. -
Sally Lightfoot Crab
Stephen Nowak Sally Lightfoot Crab Scientific Name: Arthropoda Crustacea Decapoda Grapsidae Grapsus grapsus Spanish Name: Abuete Negro Closest Relative: Percnon gibbesi Atlantic Ocean; Also known as Sally Lightfoot © 2004-5 Select Latin America Ltd Sally Lightfoot crab scavenging on a dead animal Geographical/Habitat: The Sally Lightfoot crab geographical local extends from the coasts of Baja California through the western coasts of Central and South America. This species of crab is a land dwelling species which spend the majority of its day on dark rocky beaches and in intertidal zones where many other animals find the constant barrage of waves too difficult to inhabit. What to Look for Physically: These creatures normally range from 5-7 cm but in the Galapagos they grow slightly larger. The Sally Lightfoot crab has developed a few adaptations to best survive in its ecological niche. As immature crabs the species' carapace is cryptically colored to match the beaches it dwells upon to remain hidden from overhead attacks from predators flying above. As the species develops, the exoskeleton becomes more difficult for these birds to break through, and sexual selection becomes the new priority to overcome. Adult Sally Lightfoot crabs are characterized by a vibrant red shell which contrasts strikingly with the lava rock beaches of the Galapagos. The name Sally Lightfoot was given to these crabs because of their agility to elude skilled trappers across the beaches. John Steinbeck comments in The Log of the Sea of Cortez “They seem to be able to run in all four directions; but more than this, perhaps because of their rapid reaction time they appear to read the mind of their hunter. -

Abstract The decapod Grapsus grapsus is commonly found on oceanic islands of the Pacific and Atlantic coasts of the Ameri- cas. In this study, a simple, quick and reliable method for detecting its larvae in plankton samples is described, which makes it ideal for large-scale studies of larval dispersal patterns in the species.
