This is a simple question with a diYcult and complex answer. Many of the largest-sized species occur in the world’s oceans. For many of these, rarity, remoteness, and quite simply the logistics of measuring these giants has made obtaining accurate size measurements diYcult. Inaccurate reports of maximum sizes run rampant through the scientific Submitted 3 October 2014 literature and popular media. -

Wilson1, J. Zhang3,15 and N. J. Bax2,16 Abstract Background: Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over the last 150 years. In May–June 2017, the IN2017_V03 expedition of the RV Investigator sampled LBA benthic communities along the lower slope and abyss of Australia’s eastern margin from off mid-Tasmania (42°S) to the Coral Sea (23°S), with particular emphasis on describing and analysing patterns of biodiversity that occur within a newly declared network of offshore marine parks. Methods: The study design was to deploy a 4 m (metal) beam trawl and Brenke sled to collect samples on soft sediment substrata at the target seafloor depths of 2500 and 4000 m at every 1.5 degrees of latitude along the western boundary of the Tasman Sea from 42° to 23°S, traversing seven Australian Marine Parks. -

The colors and abundance of life consis- tently delight me and also remind me of how vulnerable these systems are. In this issue of blue, we’ll journey to one of the most remote tropical coral reef systems on the planet. In September, a team of scientists from the Aquarium, the Woods Hole Oceano- graphic Institution and other collaborators visited the Phoenix Islands Protected Area (PIPA), one of the largest marine protected areas in the world.

Contr. Tert. Quatern. Geol. 32(4) 97-132 43 figs Leiden, December 1995 An outline of cassoidean phylogeny (Mollusca, Gastropoda) Frank Riedel Berlin, Germany Riedel, Frank. An outline of cassoidean phylogeny (Mollusca, Gastropoda). — Contr. Tert. Quatern. Geo!., 32(4): 97-132, 43 figs. Leiden, December 1995. The phylogeny of cassoidean gastropods is reviewed, incorporating most of the biological and palaeontological data from the literature. Several characters have been checked personally and some new data are presented and included in the cladistic analysis. The Laubierinioidea, Calyptraeoidea and Capuloidea are used as outgroups. Twenty-three apomorphies are discussed and used to define cassoid relations at the subfamily level. A classification is presented in which only three families are recognised. The Ranellidae contains the subfamilies Bursinae, Cymatiinae and Ranellinae. The Pisanianurinae is removed from the Ranellidae and attributed to the Laubierinioidea.The Cassidae include the Cassinae, Oocorythinae, Phaliinae and Tonninae. The Ranellinae and Oocorythinae are and considered the of their families. The third the both paraphyletic taxa are to represent stem-groups family, Personidae, cannot be subdivided and for anatomical evolved from Cretaceous into subfamilies reasons probably the same Early gastropod ancestor as the Ranellidae. have from Ranellidae the Late Cretaceous.

Teachers are strongly encouraged to adapt activities included in this guide to meet the specific needs of the grades they teach and their students. Activities developed for this guide support Next Generation Science Standards (NGSS), Ocean Literacy Principles, National Geography Standards and Common Core Language Arts (see page 27 for a standards alignment chart). An extraordinary journey into the mysterious world of one of nature’s most awe-inspiring marine mammals, Humpback Whales takes audiences to Alaska, Hawaii and the remote islands of Tonga for an immersive look at how these whales communicate, sing, feed, play and take care of their young. Captured for the first time with IMAX® 3D cameras, and found in every ocean on earth, humpbacks were nearly driven to extinction 50 years ago, but today are making a steady recovery. Join a team of researchers as they unlock the secrets of the humpback and find out what makes humpbacks the most acrobatic of all whales, why they sing their haunting songs, and why these 55-foot, 50-ton animals migrate up to 10,000 miles round-trip every year. -
Gradual Miocene to Pleistocene Uplift of the Central American Isthmus: Evidence from Tropical American Tonnoidean Gastropods Alan G
J. Paleont., 75(3), 2001, pp. 706±720 Copyright q 2001, The Paleontological Society 0022-3360/01/0075-706$03.00 GRADUAL MIOCENE TO PLEISTOCENE UPLIFT OF THE CENTRAL AMERICAN ISTHMUS: EVIDENCE FROM TROPICAL AMERICAN TONNOIDEAN GASTROPODS ALAN G. BEU Institute of Geological and Nuclear Sciences, P O Box 30368, Lower Hutt, New Zealand, ,[email protected]. ABSTRACTÐTonnoidean gastropods have planktotrophic larval lives of up to a year and are widely dispersed in ocean currents; the larvae maintain genetic exchange between adult populations. They therefore are expected to respond rapidly to new geographic barriers by either extinction or speciation. Fossil tonnoideans on the opposite coast of the Americas from their present-day range demonstrate that larval transport still was possible through Central America at the time of deposition of the fossils. Early Miocene occurrences of Cypraecassis tenuis (now eastern Paci®c) in the Caribbean probably indicate that constriction of the Central American seaway had commenced by Middle Miocene time. Pliocene larval transport through the seaway is demonstrated by Bursa rugosa (now eastern Paci®c) in Caribbean Miocene-latest Pliocene/Early Pleistocene rocks; Crossata ventricosa (eastern Paci®c) in late Pliocene rocks of Atlantic Panama; Distorsio clathrata (western Atlantic) in middle Pliocene rocks of Ecuador; Cymatium wiegmanni (eastern Paci®c) in middle Pliocene rocks of Atlantic Costa Rica; Sconsia sublaevigata (western Atlantic) in Pliocene rocks of Darien, Paci®c Panama; and Distorsio constricta (eastern Paci®c) in latest Pliocene-Early Pleistocene rocks of Atlantic Costa Rica. Continued Early or middle Pleistocene connections are demonstrated by Cymatium cingulatum (now Atlantic) in the Armuelles Formation of Paci®c Panama. -

Birds, fish, and mammals are active during these times. Look for churning water surfaces, diving birds, shiny dolphin backs, seals and otters in bays and on open water. Listen for songbirds singing in bushes and trees, especially during spring and early summer. Be calm and stay awhile. Adopt an unhurried, ‘vacation’ state of mind. A state of relaxed alertness is the best way to see wildlife. Blend in. Animals react to movement. Sit quietly next to a bush or tree and practice the ‘art of invisibility.’ Keep it steady.
