Anche il celacanto vittima della plastica - Il giornale del mare
Skip to content Il celacanto, soprannominato il fossile vivente è divenuto anch’esso vittima della plastica. Sopravvissuti anche alle piu’ grandi estinzioni, oggi questi pesci devono fare i conti con i rifiuti plastici che ogni giorno raggiungono il fondo del mare, anche là dove non arriva la luce e dove potrebbero vivere ancora tante specie sconosciute. Clicca qui per conoscere il celacanto.
La foto non è nuova ma è stata rilanciata in questi giorni da diverse testate e blog. Si tratta un esemplare di celacanto con il ventre aperto dove si vede bene che il pesce aveva ingerito plastica prima di essere stato pescato . E, non sarebbe la prima volta che materie plastiche siano state ritrovate all’interno dell’apparato digerente di questi pesci preistorici ma ancora presenti nelle acque delle isole Comore, in Sulawesi, in Tanzania, in Monzambico , in Madagascar ed in Kenia.
Sembra non sia solo la plastica a cercare di frenare cio’ che milioni di anni di evoluzione non hanno cambiato . Alcuni studi scientifici mostrano concentrazioni altissime di para-diclorodifeniltricloroetano meglio conosciuto come DDT nei tessuti del celacanto . Sembra che la molecola utilizzata per proteggere i raccolti nei paesi dell’Africa del centrale e del sud riescano a viaggiare sino all’oceano indiano entrando nella catena alimentare.
