Caribbean Reef Squid)
UWI The Online Guide to the Animals of Trinidad and Tobago Ecology Sepioteuthis sepioidea (Caribbean Reef Squid) Order: Teuthida (Squid) Class: Cephalopoda (Octopuses, Squid and Cuttlefish) Phylum: Mollusca (Molluscs) Fig. 1. Caribbean reef squid, Sepioteuthis sepioidea. [http://www.arkive.org/caribbean-reef-squid/sepioteuthis-sepioidea/image-G76785.html, downloaded 10 March 2016] TRAITS. The mantle (body mass) is wide and relatively flattened, with a length of 114mm in adult males and 120 mm in adult females (Moynihan and Rodaniche, 1982). A skeleton is absent but a cartilaginous layer is normally found beneath the surface of the mantle which enables movement (Mather et al., 2010).Two fins span the length of the lateral mantle margins (Fig. 1). The head is slightly pointed to its anterior end, with eight arms and two tentacles which encircle the mouth (Mather et al., 2010). Suckers are positioned along the inner region of arms and tentacle clubs. The mantle is fleshy when relaxed and the skin is very fragile (Moynihan and Rodaniche, 1982). The colour patterns of the skin can change periodically, due to the existence of light-reflective and iridescence-inducing cells (Mather, 2010). DISTRIBUTION. Distributed throughout the West Indian islands, including Trinidad and Tobago; widespread along the Central and South American coasts adjacent to the Caribbean Sea and also found in Bermuda and Florida (Moynihan and Rodaniche, 1982). UWI The Online Guide to the Animals of Trinidad and Tobago Ecology HABITAT AND ACTIVITY. Found in highly saline, clear waters of marine habitats at varying depths and distances from shoreline (Wood et al., 2008). The depth and habitat they are observed at depends on their growth stage (Mather et al., 2010). -
<I>Syringodium Filiforme</I>
BULLETIN OF MARINE SCIENCE, 83(3): 571–585, 2008 LEAF GROWTH OF THE SEAGRASS SYRINGODIUM FILIFORME IN OUTER FLORIDA BAY, FLORIDA Arthur C. Schwarzschild, W. Judson Kenworthy, and Joseph C. Zieman ABSTRACT Leaf growth of the seagrass Syringodium filiforme (Kütz., 1860) was determined using a new technique based on the growth of emergent leaves (EL method) and compared to the more labor intensive repeated measurements (RM) and demo- graphic allometric age reconstruction techniques (DA). All three techniques were used to compare leaf growth dynamics of plants with different morphologies at two sites, a shallow water (0.5 m) banktop and an adjacent deeper water (1.5 m) environ- ment in outer Florida Bay, Florida. Leaf formation rates (Leaf Plastochrone Interval or PI) determined using the EL and RM methods were nearly identical, with means of 20 and 21 d leaf–1 at both sites, significantly faster than the 30 d leaf–1 calculated using the DA method. The EL method produced the highest estimate of leaf growth, 1.8 and 1.9 cm d–1 at the 0.5 m and 1.5 m sites, respectively, followed by the RM method (1.3 and 1.3 cm d–1) and the DA method (1.0 and 1.1 cm d–1). None of the methods detected differences in leaf PI, leaf growth or leaf fragmentation rates be- tween sites. However, leaves at the 1.5 m site typically retained intact leaf tips longer than those at the 0.5 m site, and total leaf lifespan was longer at the 1.5 m site. -

Seagrasses have key ecological roles in coastal ecosystems and can form extensive meadows supporting high biodiversity. The global species diversity of seagrasses is low (b60 species), but species can have ranges that extend for thousands of kilometers of coastline. Seagrass bioregions are defined here, based on species assemblages, species distributional ranges, and tropical and temperate influences. Six global bioregions are presented: four temperate and two tropical. The temperate bioregions include the Temperate North Atlantic, the Temperate North Pacific, the Mediterranean, and the Temperate Southern Oceans. The Temperate North Atlantic has low seagrass diversity, the major species being Zostera marina, typically occurring in estuaries and lagoons. The Temperate North Pacific has high seagrass diversity with Zostera spp. in estuaries and lagoons as well as Phyllospadix spp. in the surf zone. The Mediterranean region has clear water with vast meadows of moderate diversity of both temperate and tropical seagrasses, dominated by deep-growing Posidonia oceanica. -

ABSTRACT This paper examines chemical nutritional aspects of three seagrass species (Thalassia testudinum König, Halodule wrightii Ascherson, and Syringodium filiforme Kützing) found at Laguna de Términos, Campeche, Mexico during the rainy season of 2004, following analysis methods described by the Association of Official Analytical Chemists. High protein (8.47- 10.43%), high crude fiber (15.70-19.43%), high ash (23.43-38.77%) high nitrogen-free extract contents (37.27-45.37%), and low lipid levels (0.83-2.13%) were common features of the three species analyzed. Given its chemical contents and the World Health Organization reference standards, particularly the high protein (10.43%), high ash (23.43%), high fiber (19.43%), high nitrogen-free extract (45.37%) and low lipids (2.13%), S. filiforme appears to be a noteworthy potential dietary supplement and a nutrient source for human consumption. Another use of this high-protein seagrass could be in producing food for aquaculture fish. Key words: Halodule wrightii, Laguna de Términos, proximate analysis, Syringodium filiforme, Thalassia testudinum. -
Effects of Two Hurricanes on Syringodium Filiforme, Manatee Grass, Within the Loxahatchee River Estuary, Southeast Florida
Estuaries and Coasts Vol. 29, No. 6A, p. 1019–1025 December 2006 Effects of Two Hurricanes on Syringodium filiforme, Manatee Grass, Within the Loxahatchee River Estuary, Southeast Florida MARY S. RIDLER,RICHARD C. DENT, and D. ALBREY ARRINGTON* Loxahatchee River District, 2500 Jupiter Park Drive, Jupiter, Florida 33458 ABSTRACT: In September 2004, the Loxahatchee River Estuary was affected by Hurricanes Frances and Jeanne, which resulted in a monthly rainfall record of 610 mm and abnormally high freshwater discharges to the system. The occurrence, density, and biomass of Syringodium filiforme in the Loxahatchee River Estuary declined significantly following the September 2004 storms based on 15 mo of pre-hurricane monitoring and 12 mo of post-hurricane monitoring. Throughout post- hurricane monitoring, S. filiforme showed no sign of recovery, though Halophila johnsonii increased considerably during the post-hurricane period. Freshwater discharges resulting from the September 2004 hurricanes lowered minimum daily salinity values to near zero and increased standard deviation of daily salinity values to 11%. Extremely low minimum daily salinity values and high daily salinity fluctuations likely resulted in the observed decline of S. filiforme. We advise the use of minimum daily salinity values when assessing seagrass habitat suitability or when modeling the effects of alternative water management scenarios. Introduction of seagrasses in the Loxahatchee River Estuary. Estuaries receive considerable attention from Because seagrasses have been deemed a valued local stakeholders and natural resource managers ecosystem component, they will be used to assess because they provide essential nursery habitats that restoration success following modified freshwater support the development of larval and juvenile fish inflows resulting from the Comprehensive Ever- and invertebrates (Montague and Ley 1993; Four- glades Restoration Project and the Northwest Fork qurean et al. -
Sirenian Feeding Apparatus: Functional Morphology of Feeding Involving Perioral Bristles and Associated Structures
THE SIRENIAN FEEDING APPARATUS: FUNCTIONAL MORPHOLOGY OF FEEDING INVOLVING PERIORAL BRISTLES AND ASSOCIATED STRUCTURES By CHRISTOPHER DOUGLAS MARSHALL A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNrVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REOUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 1997 DEDICATION to us simply as I dedicate this work to the memory of J. Rooker (known "Rooker") and to sirenian conservation. Rooker was a subject involved in the study during the 1993 sampling year at Lowry Park Zoological Gardens. Rooker died during the red tide event in May of 1996; approximately 140 other manatees also died. During his rehabilitation at Lowry Park Zoo, Rooker provided much information regarding the mechanism of manatee feeding and use of the perioral bristles. The "mortality incident" involving the red tide event in southwest Florida during the summer of 1996 should serve as a reminder that the Florida manatee population and the status of all sirenians is precarious. Although some estimates suggest that the Florida manatee population may be stable, annual mortality numbers as well as habitat degradation continue to increase. Sirenian conservation and research efforts must continue. ii ACKNOWLEDGMENTS Research involving Florida manatees required that I work with several different government agencies and private parks. The staff of the Sirenia Project, U.S. Geological Service, Biological Resources Division - Florida Caribbean Science Center has been most helpful in conducting the behavioral aspect of this research and allowed this work to occur under their permit (U.S. Fish and Wildlife Permit number PRT-791721).

Included are 12 species of seagrasses, 18 species of mangrove and 278 species of marine algae. Seagrasses and mangroves in the region have been comparatively well surveyed and their taxonomy is stable, so it is unlikely that further species will be recorded. However, the marine algae have been collected and documented only more recently and it is estimated that further surveys will increase the number of recorded species to over 400. The bulk of the marine flora comprised widespread Indo-West Pacific species, but there were also many endemic species with more endemics reported from the inshore areas than the offshore atolls. This number also will increase with the description of new species from the region. Collecting across the region has been highly variable due to the remote location, logistical difficulties and resource limitations. -
