@blablux@piaille.fr il y en aussi de très beaux spécimens encore bien conservés autour de Lyon et dans la vallée du Rhône. Ils reliaient Paris à Marseille.

Given my professional background (perversion) in evolutionary ecology, I can't help but wonder: OK, that sounds cool, but how much does this fancy feature costs in fitness ? I probably can't afford it...
High functional responses predispose fish species to invasiveness, but these trophic advantages do not necessarily persist outside their native range. Congratulation to Marine and Chloé for this nice paper!

Contrary to our expectations, our study of the invasive round goby in Ontario found that bold, proactive personalities did not drive range expansion, challenging the idea that behaviour fuels invasion spread.

@chaprot@pouet.chapril.org Haha, les enfants de 7 ans savent poser les bonnes questions.
Oui, en quelque sorte. Comme la plupart des mollusques (famille à laquelle appartiennent également les escargots), la plupart des poulpes ont une langue râpeuse appelée radula. Elle est un peu différente de notre langue souple et musculeuse, mais elle se trouve dans la cavité buccale et aide à ingérer les aliments. C'est même l'un des caractères taxinomiques des mollusques.
@chaprot@pouet.chapril.org Et pour répondre à la question suivante : les poissons, eux, n'ont pas de salive, juste un mucus lubrifiant dépourvu d'enzyme digestive.
