Si algun cop, bussejant, has vist una petita taca de colors ne\u00f3 movent-se sobre una esponja o una alga, \u00e9s molt probable que hagis descobert un dels animals m\u00e9s espectaculars dels oceans: un <\/span>nudibranqui<\/b>.

Per qu\u00e8 Nudibranquis?<\/h2>\n

El seu nom prov\u00e9 del llat\u00ed nudus<\/em> (nu) i del grec brankhia<\/em> (br\u00e0nquies).<\/p>\n

La segona part del nom ja ens diu com respiren.<\/p>\n

Pel que fa a la primera part\u2026 s\u00f3n cosins evolutius dels cargols (pertanyen a la classe Gasteropoda); per\u00f2, a difer\u00e8ncia d\u2019ells, no tenen closca\u2026 Per aix\u00f2 s\u00f3n \u00abnus\u00bb, en certa manera com els llimacs.<\/p>\n

Eh, per\u00f2 no tenen closca\u2026 en la fase adulta. Quan surten de l\u2019ou s\u00ed que en tenen (molt lleugera), per\u00f2 l\u2019acaben \u201cperdent\u201d quan deixen enrere la fase larv\u00e0ria. De fet, el cicle vital dels nudibranquis podria ocupar una entrada sencera del blog.<\/p>\n

Impressionisme sota l\u2019aigua<\/h2>\n

Els nudibranquis s\u00f3n, sens dubte, alguns dels animals m\u00e9s acolorits de la Mediterr\u00e0nia. Els nudibranquis formen part del grup dels anomenats \u00abllimacs de mar\u00bb (tot i que no tots els llimacs de mar s\u00f3n nudibranquis). Tamb\u00e9 se\u2019ls anomena \u201cpapallones de mar\u201d, en refer\u00e8ncia a l\u2019explosi\u00f3 de colors que presenten. Parlem d\u2019una gamma de colors pr\u00e0cticament infinita. <\/p>\n

Els colors de molts nudibranquis poden ser deguts a pigments acumulats a trav\u00e9s de la dieta o per coloraci\u00f3 estructural, produ\u00efda quan la llum interactua amb estructures microsc\u00f2piques del cos. Com si fossin p\u00edxels reflectants, o tra\u00e7os d\u2019una pintura \u201cnanopuntillista\u201d: un Seurat profund i viu. Per cert, no s\u00f3n els \u00fanics animals que juguen amb la llum a escala microsc\u00f2pica: els camaleons tamb\u00e9 poden produir part dels seus colors mitjan\u00e7ant estructures nanosc\u00f2piques que modifiquen la llum que reflecteixen.<\/p>\n

La seva coloraci\u00f3 no respon a criteris est\u00e8tics ni d\u2019aparellament. De fet, els nudibranquis tenen una visi\u00f3 molt limitada i una capacitat molt baixa per distingir els colors. Els seus colors, en diverses esp\u00e8cies, funciona com un senyal d\u2019advert\u00e8ncia associat a les seves defenses. Com un cartell de \u00abperill: no us apropeu i sobretot no em devoreu\u00bb.<\/p>\n

[Per si voleu posar-vos t\u00e8cnics: aquesta coloraci\u00f3 d\u2019av\u00eds, habitual en animals t\u00f2xics o verinosos, s\u2019anomena aposematisme<\/em>.]<\/p>\n

Perill\u2026 de qu\u00e8?<\/h3>\n

Molts nudibranquis tenen defenses qu\u00edmiques, i en diverses esp\u00e8cies aquestes defenses van associades a aquesta coloraci\u00f3 vistosa que actua com un senyal d\u2019advert\u00e8ncia per als depredadors.<\/p>\n

Tot i aix\u00f2, s\u2019han identificat nudibranquis amb colors llampants que no s\u00f3n verinosos: en aquest cas, utilitzen el senyal d\u2019alerta associada als colors vius per protegir-se dels depredadors, sense haver de destinar energia a ser verinosos.<\/p>\n

[Un fenomen semblant es dona en els s\u00edrfids, uns insectes totalment inofensius, per\u00f2 que presenten ratlles grogues i negres, com les abelles o les vespes, per dissuadir els possibles depredadors. (A aquest fals aposematisme<\/em> tamb\u00e9 se\u2019l coneix com a mimetisme batesi\u00e0<\/em>).]<\/p>\n

Ah! I tamb\u00e9 hi ha nudibranquis que no tenen colors que destaquen, precisament perqu\u00e8 la seva estrat\u00e8gia de defensa es basa en el camuflatge amb el seu entorn.
Per\u00f2 centrem-nos en els nudibranquis verinosos.<\/p>\n

Lladres que no s\u2019amaguen<\/h2>\n

Alguns nudibranquis no produeixen directament les seves defenses qu\u00edmiques, sin\u00f3 que necessiten \u201crobar-les\u201d als organismes dels quals s\u2019alimenten. <\/p>\n

Per exemple, els nudibranquis que s\u2019alimenten de cnidaris verinosos (meduses o anemones) en lloc de digerir les c\u00e8l\u00b7lules urticants de les seves preses, les transporten intactes fins a les puntes de determinades protuber\u00e0ncies del cos, i les allotgen en sacs especials. Qualsevol animal que toqui o intenti menjar-se el nudibranqui pot rebre la fiblada provocada per aquestes c\u00e8l\u00b7lules urticants. <\/p>\n

Altres nudibranquis incorporen les toxines de les esponges que mengen: algunes esp\u00e8cies les acumulen directament, mentre que d\u2019altres les poden modificar.<\/p>\n

Troba\u2019ls a la BioMARat\u00f3!<\/h2>\n

Els nudibranquis poden ser uns bons indicadors dels canvis ambientals que experimenten els ecosistemes marins. Com que s\u00f3n animals bent\u00f2nics, tenen una mobilitat limitada i sovint depenen estretament del seu h\u00e0bitat i dels organismes dels quals s\u2019alimenten, els canvis en la seva pres\u00e8ncia, abund\u00e0ncia o distribuci\u00f3 poden proporcionar informaci\u00f3 valuosa sobre l\u2019ecosistema.<\/p>\n

Trobar-los requereix paci\u00e8ncia i \u00abull de bussejador\u00bb, ja que molts s\u00f3n petits i viuen amagats a les esquerdes de les roques o perfectament camuflats sobre el seu aliment.\u00a0 De fet, aprendre a observar-los i fotografiar-los \u00e9s gaireb\u00e9 una disciplina en si mateixa. <\/span>Xavier Salvador<\/span><\/a>, col\u00b7laborador de MINKA, validador d’esp\u00e8cies i autor de la <\/span>Gu\u00eda pr\u00e1ctica para fotografiar nudibranquios en el litoral espa\u00f1ol<\/span><\/i>, explica que con\u00e8ixer l\u2019h\u00e0bitat de cada esp\u00e8cie \u00e9s una de les claus per trobar-la i identificar-la correctament.

Si t\u2019interessen aquests animals, pots participar al projecte Llimacs marins de Catalunya de MINKA, una iniciativa de ci\u00e8ncia ciutadana liderada per Miquel Pontes, i creada per recopilar observacions. Actualment ja compta amb prop de 30.000 observacions, gaireb\u00e9 300 esp\u00e8cies registrades i m\u00e9s de 500 observadors, fet que la converteix en una de les principals fonts d\u2019informaci\u00f3 sobre aquests animals a Catalunya.<\/p>\n
