Kuuba pyrkii pelastamaan dinosaurusten aikaisen kalan – uhanalainen laji vaarassa

The manjuari, a remarkable fish species, faces a critical threat to ‍its survival. This ancient creature, possibly dating back 150 million years, ​is now teetering on the brink of extinction. You ​might be surprised to learn this fish existed alongside the dinosaurs.

Currently, conservation efforts are underway in Cuba’s Zapata⁣ swamp, the largest natural reserve in the Caribbean. Biologists are working tirelessly to rescue the Cuban giant sawfish, as ⁣the manjuari is also known. It’s a race against time to protect this biological relic.

Here’s what makes the manjuari so special:

* ‍ Ancient ​Lineage: ‍ It’s a living fossil, having survived for an amazing 140-150 million years.
* Unique Appearance: The manjuari is characterized by its long,slender body and sharp teeth.
* Critical Status: Classified as ‍critically endangered in Cuba and listed on the ‌International Union for Conservation of Nature’s (IUCN) Red List as 2020.
*‌ ⁣ Ecological Importance: Considered a true “jewel” of ⁤Cuban fish fauna.

However, the‍ manjuari population has plummeted dramatically in recent years. A key factor is the introduction of an invasive species – the Asian swamp eel – in the late 1990s.‍ This non-native⁣ predator has devastated the previously pristine wetland⁣ habitat.‍

I’ve found that innovative solutions are often needed in these situations. Fortunately, a breakthrough has emerged. Biologists have developed a method for⁣ successfully breeding the challenging manjuari in captivity.

Here’s ‍how the recovery program works:

1. Manjuari are spawned at a nearby aquaculture facility.
2. Biologists carefully nurture the young fish,which start out⁢ incredibly small – about the size of a pencil.
3. once mature, the ⁣manjuari are​ reintroduced into​ their​ natural habitat.

This approach offers ‌a beacon of ​hope for the future of this extraordinary species. It’s a testament to⁣ the dedication​ and‍ ingenuity of the conservation team. Protecting ‌the manjuari isn’t just about saving a single fish; it’s about preserving a piece of our planet’s ancient history.
