Summary
[edit]DescriptionVelella velella 2009.jpg |
Français : J'ai trouvé ces "petites bêtes" échouées, mais encore vivantes, sur une plage réthaise il y a quelques jours. En le observant bien, elles sont identiques (partie inférieure) à des étoiles de mer.Ce qui laisse à penser que ce sont des échinodermes. Par contre je n'ai jamais vu de telles animaux sur ces plages que je pratique à la pêche depuis plus de 60ans. Leur "voile" hélicoïdale laisse à penser qu'elle se laissent porter par les courants. Mais d'où viennent elles? Merci de nous le faire savoir. |
