🇫🇷 Les globicéphales sont des baleines à dents qui peuvent atteindre une taille imposante de 5m. Leur organisation sociale est assez proche de celle des dauphins notamment pour des évènements dont l'explication pose encore beaucoup de question : les échouages.

Chaque année, l'archipel du Cap-Vert répertorie des échouages de cétacés, dauphins ou petites baleines. En général des pépenocéphales ou des globicéphales. L'origine de ces échouages demeure encore assez méconnue. Plusieurs hypothèses ressortent pour explication ces comportements.
🇬🇧 Pilot whales are toothed whales that can reach an imposing size of 5m. Their social organization is quite close to that of dolphins, particularly for events whose explanation still raises many questions: strandings.

Every year, the archipelago of Cape Verde lists strandings of cetaceans, dolphins or small whales. In general, seagulls or pilot whales. The origin of these strandings remains quite unknown. Several hypotheses emerge to explain these behaviors

🇫🇷 - La première des hypothèses nous vient d'un sens vital de ces animaux : l'acoustique. Ces animaux utilisent un "sonar" naturel pour se répérer et émettent de nombreux type de sons pour communiquer également. Une hypothèse consiste à expliquer que pour une raison ou une autre, un dérangement tiers ne permet plus à ces animaux de se s'orienter. Si l'on chercher du côté humain, cela pourrait provenir de bateaux à fort décibels, de propections pétrolières, ou de lâcher d'explosifs militaires. Perdus, ils finissent par s'échouer sans savoir où aller.

-Une deuxième hypothèse met en avant la solidarité extrême des ces animaux et peut-être la mort du leader ou de l'un des membres du groupe. L'ensemble des individus suivraient alors le membre mourant par solidarité.

- Enfin l'hypothèse de la maladie est également évoquée mais si elle s'avérait correcte, il semblerait que par les moyens médicaux de nos jours, il serait assez facile de la prouver.
🇬🇧 - The first hypothesis comes from a vital sense of these animals: acoustics. These animals use a natural "sonar" to detect themselves and emit many types of sounds to communicate as well. A hypothesis consists of explaining that for one reason or another, a third-party disturbance no longer allows these animals to orient themselves. If we look on the human side, it could come from boats with high decibels, from oil projects, or from releasing military explosives. Lost, they end up running aground without knowing where to go.

-A second hypothesis highlights the extreme solidarity of these animals and perhaps the death of the leader or one of the group members. The set of individuals would then follow the dying member in solidarity.

- Finally, the hypothesis of the disease is also mentioned but if it turned out to be correct, it seems that by medical means nowadays, it would be quite easy to prove it.

🇫🇷 Quoiqu'il en soit, la semaine dernière encore un group de quelques dizaines d'individus s'est échoué sur l'une des plages de Boa Vista au Cap-Vert. Les restes des animaux ont fini par se décomposer en abandonnant quelques morceaux à la mer. Cela a pour habitude d'attirer d'autres animaux, les plus gros charognards de la mer, les requins. Les requins coursent très rarement des proies vivantes et dynamiques, comme le font les dauphins par exemples. Ce sont des fainéants, des charognards, qui préfèrent s'attaquer aux proies faibles ou mortes. Ils nettoient ainsi les océans des cadavres et de leurs maladies. UQuelques jours après l'échouage du groupe de globicéphales, je me suis rendu sur place et ai envoyé mon drone pour vérifier si certains requins avaient été attirés par les restes décomposés des cétacés. Je n'ai pas cherché très longtemps pour ttrouver les premiers squales. Deux gros requins tigres et certainement d'autres plus petits attendant leur tour, étaient déjà présents sur le site. Certains n'hésitant pas à risquer de s'échouer à leur tour pour récupérer les restes des globicéphales. Je vous laisse avec mes photographies de drone et une vidéo.
🇬🇧 Anyway, last week a group of a few dozen individuals was stranded on one of the beaches of Boa Vista in Cape Verde. The remains of the animals eventually decomposed by leaving a few pieces at sea. This is used to attract other animals, the biggest scavengers of the sea, sharks. Sharks very rarely chase live and dynamic prey, as dolphins do for example. They are slackers, scavengers, who prefer to attack weak or dead prey. They thus cleanse the oceans of corpses and their diseases. Only days after the beaching of the group of pilot whales, I went to the site and sent my drone to check if some sharks had been attracted by the decomposed remains of cetaceans. I didn’t look very long to find the first sharks. Two large tiger sharks and certainly other smaller ones waiting their turn, were already present on the site. Some do not hesitate to risk running aground in their turn to retrieve the remains of pilot whales. I leave you with my drone photographs and a video.

Great shots, such a shame when situations occur like this but nature takes its course.

When it happens in the UK, it is mostly theorised that they have become deteriorated or lost.

Maybe the local wildlife department would find your shots interesting?

Incredible read and watch! As someone fascinated by sea animals, this is interesting to ponder about and I guess it could be the first hypothesis, sound disruptions means losing all sense of coordination and getting lost in this vast ocean :/

It's interesting to hear that these strandings happen often. There must be a better explanation for this behaviour?

Well done for getting the images 📸👍
