“…Such studies range from broad "big picture" topics such as social structure (e.g., Lusseau et al, 2003;Rogers, Brunnick, Herzing, & Baldwin, 2004;Wells, Scott, & Irvine, 1987) to specific social interactions, such as mother-calf interactions (e.g., Gibson & Mann, 2008a, b), the "herding" behavior of male alliances (Connor, Smolker & Bejder, 2006;Connor, Smolker, & Richards, 1992), and social tactile behaviors (e.g., Dudzinski, Gregg, Ribic, & Kuczaj, 2012;Dudzinski et al, 2009;Tamaki, Morisaka, & Taki, 2006). Although a few studies have reported on social play in bottlenose dolphins (Kuczaj, Paulos, & Ramos, 2005;Mann & Smuts, 1999;McBride & Krtizler,1951;Tayler & Saayman, 1972), no study to date has investigated the developmental patterns of social play in this species, including the role of different play partners in these interactions.…”

-For the young of many species, social play is an important aspect of development. Previous research has shown that bottlenose dolphin calves engage in social play early in life. Despite these observations, little is known about the development of social play in this species. The present study examined the social play behavior of three aquarium-housed bottlenose dolphin calves during their first year of life. We were particularly interested in the partner with whom each calf played as well as the initiator of social play bouts. Each calf was observed from birth until the end of its first year and all bouts of social and solitary play were recorded during observation sessions. While the calves engaged in both social and solitary play throughout their first year, play became increasingly social as they aged. The calves also became more likely to initiate social play interactions with increasing age. A calf's first social play partner was typically its mother, but other calves quickly replaced the mother as the most common play partner. When it came to play partner preferences, we found that calves of similar age were preferred as play partners, but age similarity became less characteristic of play partners as the calves grew older. These findings likely reflect changes in the developmental competence of each of the calves individually, and support the notion that calves use social play to challenge themselves. Keywords -Social play, Bottlenose dolphins; Development; Play partner preference; Tursiops truncatusSocial play, or play behavior directed at conspecifics (Burghardt, 2005), is evident in a variety of species and is especially salient in those with complex social structures. Social play has been reported in both human (e.g., Doyle, Connolly, & Rivest, 1980;Eckerman, Whatley, & Kutz, 1975;Fry, 2005) and non-human primates (e.g., Cordoni & Palagi, 2011;Harlow & Harlow, 1962;Hoff, Nadler, & Maple, 1981;de Oliveira, Ruiz-Miranda, Kleiman, & Beck, 2003), as well as a variety of terrestrial mammals (e.g., Byers, 1977;Drea, Hawk, & Glickman, 1996;Henry & Herrero, 1974;Lee, 1987;Wemmer & Fleming, 1974), aquatic mammals (e.g., Blomqvist, Mello, & Amundin, 2005Essapian, 1953;Gentry, 1974;Kuczaj, Makecha, Trone, Paulos, & Ramos, 2006;Mann & Smuts, 1999;McBride & Hebb, 1948;Renouf & Lawson, 1986; Spinelli, Nascimento, & Yamamato, 2002;Sylvestre, 1985), birds (e.g., Diamond & Bond, 2003; Pozis-Francios, Zahavi, & Zahavi, 2004), and even reptiles (e.g., Burghardt, 1998). The ubiquitous presence of social play in highly social species highlights the need for studies aimed at understanding the various aspects of this behavior and the role it plays in social interactions.One aquatic species in which social play is evident, but little studied, is the bottlenose dolphin,

A. O. Debrot, J.E.Tamis, D. de Haan, M. Scheidat, J.T. van der Wal, 2017 was formally established on September 2, 2015. It is currently composed of two sectors: one surrounding Saba and the Saba Bank and one covering the EEZ waters of Bonaire. In order to help establish an effective cetacean conservation management plan for the Saba and Saba Bank sector of the sanctuary we here review the main marine mammal threats, help identify main management goals and make both governance and management recommendations based both on stakeholder interviews and a management review of functioning marine mammal sanctuaries in the WesternAtlantic.There are 8 species of marine mammals known to occur in the windward Dutch Caribbean YarariSanctuary. The sanctuary has relatively low levels of human activity. Based on our review, cumulative contaminant impacts -such as oil contamination originating from St. Eustatius -are potentially highest, followed by collision impacts due to the relatively high level of shipping traffic. Other factors such as, fishery entanglement, bycatch-impacts and marine debris impacts are likely low compared to many areas directly outside the sanctuary. While whale & dolphin watching impacts are still probably negligible, the impacts of anthropogenic noise, climate-change impacts and cumulative impacts still remain unknown but are potentially high.Five main clusters of interrelated goals and objectives were identified based on expert and management stakeholder interviews. The most essential proximate goal for management should be to establish a minimum structural level of institutional capacity. Under the reigning conditions of resource limitation, the next key goal should be to establish effective collaboration towards jointly achieving the higher management goals and objectives.Based on our review of species, threats, operations of other sanctuaries and expert and stakeholder input we list 23 priority recommendations and action points towards implementation of cetacean conservation for the Saba and Saba Bank Yarari sector. Governance• Use the Saba Bank Management Unit (SMBU) governance model for Yarari management implementation.• Consider merging Yarari tasks into the SMBU to effectuate resource pooling and prevent management fragmentation. Legal resources• Design and implement a simple legal mandate for Yarari management.• Copy and implement international legal guidelines for whale watching.• Revise the Fishery Framework Act BES (Vissery Visserijwet besluit BES) or draft a Decree (Regeling) under the Nature Conservation Framework Act BES (Wet Grondslagen Natuurbeheer en-bescherming, WGN) to forbid all forms of pelagic (not benthic) longline and purse seine fishing in Yarari waters.• Devise and implement legal measures and guidelines to safeguard Yarari from anthropogenic noise pollution. Finances• Based on the review of functioning sanctuaries, and current stressor levels, a basic annual budget of US$ 150 K will be sufficient to implement satisfactory marine mammal conservation.• Focus expenditures on mana...
