Description

ANÉMONES ET MÉDUSES Texte et recherche de Tristan Léonard, revue LA PLONGÉE Volume 9, No. 6, Juin 1982 LES MÉDUSES: Proche parents des anémones, les méduses ont une plus mauvaise réputation. Certains leur reproche la cuisante "brûlure" de leurs tentacules, d'autres d'emplir et de briser les filets, plusieurs de détruire les types de planctons qui assurent de bonnes pêches. Certes ces cnidaires ("animaux qui piquent") sont dotés de nématocystes (cellules urticantes) qui injectent des toxines, mais rares sont celles qui peuvent gêner l'être humain. Établissons d'abord que la plupart des méduses québécoises sont très petites (6 seulement dépasseraient les 10 cm) et inoffensives. D'ailleurs beaucoup de plongeurs les confondent à du plancton. Formées à 95% d'eau, elles respirent à travers leur peau et certaines (aurélie), à travers la paroi de l'estomac. Elles se reproduisent en 6 étapes. La méduse adulte est pourvue de glandes reproductrices (gonades) où se développent des oeufs. Une fois lâchés, ces oeufs deviennent des planules (planutas), larves qui nagent grâce à des cils vibratiles. Celles-ci finissent par se fixer et forment des polypes (ressemblant à des hydres), qui bourgeonneront et formeront à leur tour des petites méduses errantes. LES MÉDUSES DANGEREUSES Des 5 espèces vraiment nuisibles à l'homme des eaux canadiennes atlantiques seulement 3 se retrouvent en eaux québécoises (Fleuve et Golfe St-Laurent). GALÈRE ou PHYSALIE Portuguese man-of-war (Physalia physalis) jusqu'à 30 cm RARE en Baie de Fundy seulement GRAVE : Urticaire linéaire ou dispersé, Douleurs ganglionnaires, Muscles et jointures endoloris, Maux de têtes - hystérie, Fièvre et frisson - Crampes et nausée ANEMONES AND JELLYFISHES Text and search for Tristan Léonard, review the DIVING Volume 9, No June 6, 1982 JELLYFISHES: Nearest relatives to the anemones, the jellyfishes have a bad reputation. Some reproaches them the cuisante "burns" their tentacles, a,d others to fill up and to break the nets, several to destroy the types of planktons which ensure of good fishings. Admittedly these cnidaires ("animals which prick") are equipped with nématocystes (irritant cells) which injects toxins, but rare are those which can obstruct the human being. Let us establish of access which the majority of the Québécois jellyfishes are very small (6 only would exceed 10 cm) and inoffensive. elsewhere much of plungers confuse them with plankton. Formed to 95% d' water, they breathe through their skin and some (aurélie), through the wall of l' stomach. They reproduce in 6 stages. The adult jellyfish is equipped with reproductive glands (gonades) where eggs develop. Once released, these eggs become planules (planutas), larvae which swim thanks to cilia. Those end up being fixed and form polyps (resembling hydres), which will bud and form in their turn of the small wandering jellyfishes. DANGEROUS JELLYFISHES GALÈRE or PHYSALIA Portuguese man-of-war (Physalia ground cherry) jusqu' to 30 cm RARE out of Bay of Fundy only SERIOUS: Linear or dispersed urticaria Ganglionic pains Muscles and joints endoloris Headaches - hysteria Fever and shiver - Cramps and nausea

Texte très interessant et instruisant. Et oui...le fractalisme permet de faire bien plus que de créer des beautés comme celle-ci.
