In its clever costume, it looks like part of the red sponge it’s resting on. That’s one of the freaky things about frogfish—lots of them don’t even look like fish! ­ Frogfish have bodies that may be strangely shaped, with funny knobs or “horns.” Their skin may be bumpy or smooth. They may be cov- ered with tassels or fringes. And some will even change color to match their surroundings.

  • The Weed That Feeds the North Atlantic
    DRIFTING PLANTS KNOWN AS SARGASSUM SUPPORT A COMPLEX AND AMAZING VARIETY OF MARINE LIFE. The Weed That Feeds the North Atlantic BY JAMES PROSEK PHOTOGRAPHS BY DAVID DOUBILET AND DAVID LIITTSCHWAGER 129 Hatchling sea turtles, like this juvenile log- gerhead, make their way from the sandy beaches where they were born toward mats of sargassum weed, finding food and refuge from predators during their first years of life. PREVIOUS PHOTO A clump of sargassum weed the size of a soccer ball drifts near Bermuda in the slow swirl of the Sargasso Sea, part of the North Atlantic gyre.

DAVID DOUBILET (BOTH) 130 NATIONAL GEOGRAPHIC THE WEED THAT FEEDS THE NORTH ATLANTIC 131 ‘There’s nothing like it in any other ocean,’ says marine biologist Brian Lapointe. ‘There’s nowhere else on our blue planet that supports such diversity in the middle of the ocean—and it’s because of the weed.’ LAPOINTE IS TALKING about a floating seaweed known as sargassum in a region of the Atlantic called the Sargasso Sea. The boundaries of this sea are vague, defined not by landmasses but by five major currents that swirl in a clockwise embrace around Bermuda. Far from any main- land, its waters are nutrient poor and therefore exceptionally clear and stunningly blue. The Sargasso Sea, part of the vast whirlpool known as the North Atlantic gyre, often has been described as an oceanic desert—and it would appear to be, if it weren’t for the floating mats of sargassum.

  • First Report of the Asian Seaweed Sargassum Filicinum Harvey (Fucales) in California, USA
    First Report of the Asian Seaweed Sargassum filicinum Harvey (Fucales) in California, USA Kathy Ann Miller1, John M. Engle2, Shinya Uwai3, Hiroshi Kawai3 1University Herbarium, University of California, Berkeley, California, USA 2 Marine Science Institute, University of California, Santa Barbara, California, USA 3 Research Center for Inland Seas, Kobe University, Rokkodai, Kobe 657–8501, Japan correspondence: Kathy Ann Miller e-mail: [email protected] fax: 1-510-643-5390 telephone: 510-387-8305 1 ABSTRACT We report the occurrence of the brown seaweed Sargassum filicinum Harvey in southern California. Sargassum filicinum is native to Japan and Korea. It is monoecious, a trait that increases its chance of establishment. In October 2003, Sargassum filicinum was collected in Long Beach Harbor. In April 2006, we discovered three populations of this species on the leeward west end of Santa Catalina Island. Many of the individuals were large, reproductive and senescent; a few were small, young but precociously reproductive. We compared the sequences of the mitochondrial cox3 gene for 6 individuals from the 3 sites at Catalina with 3 samples from 3 sites in the Seto Inland Sea, Japan region. The 9 sequences (469 bp in length) were identical. Sargassum filicinum may have been introduced through shipping to Long Beach; it may have spread to Catalina via pleasure boats from the mainland. Key words: California, cox3, invasive seaweed, Japan, macroalgae, Sargassum filicinum, Sargassum horneri INTRODUCTION The brown seaweed Sargassum muticum (Yendo) Fensholt, originally from northeast Asia, was first reported on the west coast of North America in the early 20th c. (Scagel 1956), reached southern California in 1970 (Setzer & Link 1971) and has become a common component of California intertidal and subtidal communities (Ambrose and Nelson 1982, Deysher and Norton 1982, Wilson 2001, Britton-Simmons 2004).

Read Full License Page 1/27 Abstract Background Over the last decade, intensity and frequency of Sargassum blooms in the Caribbean Sea and central Atlantic Ocean have dramatically increased, causing growing ecological, social and economic concern throughout the entire Caribbean region. These golden-brown tides form an ecosystem that maintains life for a large number of associated species, and their circulation across the Atlantic Ocean support the displacement and maybe the settlement of various species, especially microorganisms. To comprehensively identify the micro- and meiofauna associated to Sargassum, one hundred samples were collected during the 2018 tide events that were the largest ever recorded. Results We investigated the composition and the existence of specic species in three compartments, namely, Sargassum at tide sites, in the surrounding seawater, and in inland seaweed storage sites. Metabarcoding data revealed shifts between compartments in both prokaryotic and eukaryotic communities, and large differences for eukaryotes especially bryozoans, nematodes and ciliates.

  • <I>Histrio Histrio</I>
    A CONTRIBUTION 'ro THE BIOLOGY AND POSTLARVAL DEVELOPMENT OF THE SA.RGASSUM FISH, HISTRIO HISTRIO (LINNAEUS), vVITH A DISCUSSION OF THE SARGilSSUM COMPLEX' JUDITH A. ADAMS The Marine Laboratory, University of Miami ABSTRACT The early development of the Sargassum fish, Histrio histrio (Linnaeus), is described, based upon a collection of 44 larval and juvenile specimens from the Florida Current. Growth, biology, feeding and relationship to the Sargassum complex are discussed. Specimens at various stages of develop- ment are illustrated. INTRODUCTION The fishes of the family Antennariidae have attracted considerable interest because of their curious form, coloration, and behavior. Reef and bank-dwelling antennariids are widely distributed throughout warm, shallow seas in the Atlantic, Pacific, and Indian Oceans, and the pelagic member of the family, Histrio histrio, occurs in floating weed over a similar area, although wind and current may at times carry these drifters far into temperate waters. Despite, however, the interest and availability of this group, its taxonomy was not clarified until quite recently (Barbour, 1942; Schultz, 1957), and many reports were buri~d in the proliferating synonomy. Histrio histrio alone, though now regarded as belonging to a monotypic genus, has seventeen synonyms as listed by Schultz (1957). Larval stages and eggs of the Antennariidae were unknown to early workers; this led several respected biologists to attribute erroneously the "nests" of flying fish to Histrio. Subsequently, non-fertile egg rafts of solitary Histrio females were observed in aquaria. In 1954 Mosher successfully paired ripe males and females in aquaria at the Lerner Marine Laboratory, Bimini, Bahamas, and recorded the spawning and fertilization of Histrio egg rafts.

Lapointe Degree: Master of Science Year: 2016 Benthic algal species receive elevated nitrogen (N) and phosphorus (P) availability as anthropogenic activities increase the loading of nutrients into coastal waters. Pelagic species could also be responding to this nutrient enrichment. This study compared the tissue nutrient content and productivity of three benthic and two pelagic species of Sargassum. We hypothesized that the benthic species would have a higher tissue nutrient content and productivity than the pelagic species and the pelagic species would have a higher tissue nutrient content and productivity than historic data.

  • Guide to the Coastal Marine Fishes of California
    STATE OF CALIFORNIA THE RESOURCES AGENCY DEPARTMENT OF FISH AND GAME FISH BULLETIN 157 GUIDE TO THE COASTAL MARINE FISHES OF CALIFORNIA by DANIEL J. MILLER and ROBERT N. LEA Marine Resources Region 1972 ABSTRACT This is a comprehensive identification guide encompassing all shallow marine fishes within California waters. Geographic range limits, maximum size, depth range, a brief color description, and some meristic counts including, if available: fin ray counts, lateral line pores, lateral line scales, gill rakers, and vertebrae are given. Body proportions and shapes are used in the keys and a state- ment concerning the rarity or commonness in California is given for each species. In all, 554 species are described. Three of these have not been re- corded or confirmed as occurring in California waters but are included since they are apt to appear. The remainder have been recorded as occurring in an area between the Mexican and Oregon borders and offshore to at least 50 miles. Five of California species as yet have not been named or described, and ichthyologists studying these new forms have given information on identification to enable inclusion here. A dichotomous key to 144 families includes an outline figure of a repre- sentative for all but two families. Keys are presented for all larger families, and diagnostic features are pointed out on most of the figures. Illustrations are presented for all but eight species. Of the 554 species, 439 are found primarily in depths less than 400 ft., 48 are meso- or bathypelagic species, and 67 are deepwater bottom dwelling forms rarely taken in less than 400 ft.

  • SCRS/2013/132 Inventory and Ecology of Fish Species of Interest
    SCRS/ 2013/132 INVENTORY AND ECOLOGY OF FISH SPECIES OF INTEREST TO ICCAT IN THE SARGASSO SEA Brian E. Luckhurst¹ SUMMARY This paper provides information on the biology and ecology of a total of 18 different fish species whose distributions include the Sargasso Sea. These species are divided into four groups that correspond with ICCAT species groupings: Group 1 – Principal tuna species including yellowfin tuna, albacore tuna, bigeye tuna, bluefin tuna and skipjack tuna. Group 2 – Swordfish and billfishes including blue marlin, white marlin and sailfish, Group 3 – Small tunas including wahoo, blackfin tuna, Atlantic black skipjack tuna (Little Tunny) and dolphinfish, and Group 4 – Sharks including shortfin mako, blue, porbeagle, bigeye thresher and basking shark. For each species, information and data is provided on distribution, fishery landings, migration and movement patterns, reproduction, age and growth, food and feeding habits and ecology in relation to oceanographic parameters, primarily water temperature. The importance of Sargassum as essential fish habitat is discussed and is linked to the feeding habits of tunas and other pelagic predators . Flyingfishes are an important prey species in the diet of tunas and billfishes and as they are largely dependent on Sargassum mats as spawning habitat, the Sargasso Sea plays a fundamental role in the trophic web of highly migratory, pelagic species. KEYWORDS Sargasso Sea, Sargassum, tunas, swordfish, billfishes, sharks, biology, ecology, life history, oceanography ¹Brian E. Luckhurst, Consultant; Retired, Senior Marine Resources Officer, Government of Bermuda. Introduction The Sargasso Sea is located within the North Atlantic sub-tropical gyre and a series of currents define its boundaries with the most influential current being the Gulf Stream in the west.

    J. Jpn. Bot. 91: 33–40 (2016) Sargassum fusiforme (Fucales, Phaeophyceae) Has No Characteristic Stem in the Genus Sargassum a, b a Hiromori SHIMABUKURO *, Toshinobu TERAWAKI and Goro YOSHIDA aNational Research Institute of Fisheries and Environment of Inland Sea, Fisheries Research Agency, 2-17-5 Maruishi, Hatsukaichi, Hiroshima, 739-0452 JAPAN; bNational Research Institute of Fisheries Engineering, Fisheries Research Agency, 7620-7, Hasaki, Kamisu, Ibaraki, 314-0408 JAPAN *Corresponding author: [email protected] (Accepted on July 1, 2015) Sargassum fusiforme is a very useful product for fisheries and is well known in Japan; however there are few detailed reports about its morphological characteristics. This species was initially assigned to the genus Cystophyllum and was subsequently categorized in the genus Turbinaria because of a lack of distinction between its leaves and vesicles. Recently, this species was categorized in the genus Sargassum based on the results of molecular studies; however, a debate has arisen between researchers who propose that the species belongs to the genus Sargassum and those in Japan who maintain that it belongs to the genus Hizikia. This difference in opinion is caused by a large morphological variation in the leaves among the different latitudes in which the species grows. The leaves of S. fusiforme growing in temperate regions are narrow, while those growing in low-latitude regions are lanceolate with dentate margins. The branches of Sargassum spp. generally arise from the stems on the holdfast; however, the branches of S. fusiforme arise directly from the holdfast. The biennial S. fusiforme has no stem, which is a characteristic of the genus Sargassum.
