| C'est tout de même un boulot sympa que se lever tous les matins pour devoir observer les baleines !! Cette semaine a été superbe. Nous avons pu observer toutes les phases de vie des baleines à bosses. Une mère et son baleineau en pleine séance d'éducation de sauts, des phases plus discrètes avec des individus solitaire réalisant des apnée de plus 25 minutes, des séances de sauts, des mouvements de pectorales en surface, des réactions de caudales, des identifications et même ce matin de séquence de reproduction. Quoi de mieux, quoi de plus ?!! Pour rappel nous observons ces cétacés dans la baie de Sal Rei au Cap-Vert, et ceux-ci rejoignent ce pays pour y trouver des eaux chaudes et calmes afin de donner naissance à des "petits" baleineaux de 700kg avec davantage de sécurité par rapport à la température de l'eau. ICi, la mer est à 20°C, dans les pôles où les baleines vivent, elle est à 2°C. Un baleineau n'y survivrait pas... Après deux mois d'allaitement, le bébé atteindra les deux tonnes et un ou deux en plus. Il sera alors prêt à réaliser sa première migration vers le pôle Nord et prêt également à affronter les tempêtes, les prédateurs, la fatigue... 50% d'entre eux n'atteindront pas l'âge adulte. La reproduction a également lieu ici. Avec une durée de gestation de 11 à 12 mois, cela donnera le temps aux femelles de réaliser la migrations vers le nord et de revenir l'année prochaine pour mettre bas. Voilà dans le désordre tout une série de photographies qui je l'espère vous donneront envie de mieux connaître cet animal. |
It is still a nice job to get up every morning to have to observe the whales!! This week was superb. We were able to observe all the phases of life of humpback whales. A mother and her calf in the middle of jumping education session, more discreet phases with solitary individuals performing apnea of more than 25 minutes, sessions of jumps, pectoral movements on the surface, caudal reactions, of the identifications and even this morning of reproduction sequence. What better, what more?!! As a reminder, we observe these cetaceans in the bay of Sal Rei in Cape Verde, and they go to this country to find warm and calm waters in order to give birth to "small" calves of 700kg with more safety compared to the water temperature. ICi, the sea is at 20°C, in the poles where whales live, it is at 2°C. A calf would not survive... After two months of breastfeeding, the baby will reach two tons and one or two more. It will then be ready to carry out its first migration to the North Pole and also ready to face storms, predators, fatigue... 50% of them will not reach adulthood. Reproduction also takes place here. With a gestation period of 11 to 12 months, this will give the females time to migrate north and come back next year to give birth. Here in the disorder a series of photographs that I hope will make you want to know this animal better. |
