Une strat\u00e9gie de migration mill\u00e9naire pour la reproduction<\/h2>\n

 <\/p>\n

Contrairement \u00e0 ce que l\u2019on pourrait croire, les baleines \u00e0 bosse<\/strong><\/a> ne viennent pas en Martinique pour se nourrir. Elles se gavent de krill, de lan\u00e7ons et de harengs<\/strong> dans les eaux froides de l\u2019Atlantique Nord pendant les mois d\u2019\u00e9t\u00e9 bor\u00e9al, accumulant jusqu\u2019\u00e0 plusieurs centaines de kilos de graisse. Ce sont ces r\u00e9serves qui leur permettent de je\u00fbner durant tout leur s\u00e9jour dans les Cara\u00efbes.<\/p>\n

Ce qui motive leur venue, c\u2019est avant tout la reproduction<\/strong>. Les eaux martiniquaises offrent un havre de paix pour la mise bas<\/strong> et les premi\u00e8res semaines de vie du baleineau. \u00c0 sa naissance, ce dernier mesure entre 4 et 5 m\u00e8tres et peut peser plus d\u2019une tonne. Il t\u00e8te jusqu\u2019\u00e0 200 litres de lait<\/strong> par jour, un lait extr\u00eamement gras (40 %), lui permettant de prendre environ 45 \u00e0 50 kg par jour<\/strong>. Cette p\u00e9riode est cruciale, et la m\u00e8re doit pr\u00e9server son petit de tout danger jusqu\u2019\u00e0 ce qu\u2019il soit suffisamment fort pour entreprendre le long retour vers les zones de chasse.<\/p>\n

Le climat est id\u00e9al pour les jeunes c\u00e9tac\u00e9s<\/h3>\n

La Martinique offre un environnement marin optimal<\/strong> : une temp\u00e9rature constante autour de 26 \u00e0 28\u00b0C<\/strong>, des eaux calmes sur la fa\u00e7ade Cara\u00efbe, \u00e0 l\u2019abri des vents et de la houle, et une faible pr\u00e9sence de pr\u00e9dateurs naturels comme les orques ou les grands requins. Ces conditions r\u00e9unies en font une nurserie id\u00e9ale<\/strong>, qui attire chaque ann\u00e9e des dizaines de femelles gravides venues donner naissance dans le calme relatif des Cara\u00efbes.<\/p>\n

Les baleines ne sont pas seules \u00e0 profiter de cette tranquillit\u00e9. De nombreuses autres esp\u00e8ces de mammif\u00e8res marins<\/strong> fr\u00e9quentent ces eaux : les globic\u00e9phales tropicaux<\/strong><\/a>, tr\u00e8s sociaux et visibles en groupes compacts ; les cachalots pygm\u00e9es<\/strong><\/a> et cachalots nains<\/strong><\/a>, plus discrets, mais r\u00e9guliers ; les pseudorques<\/strong><\/a>, rapides et curieuses ; ou encore la baleine \u00e0 bec de Cuvier<\/strong><\/a>, plongeuse d\u2019exception capable de rester sous l\u2019eau plus de 2 heures<\/strong>. Bien que plus rare, l\u2019orque<\/strong><\/a> peut \u00e9galement \u00eatre observ\u00e9e de mani\u00e8re exceptionnelle dans certaines ann\u00e9es.<\/p>\n
