Ditemukan Fosil Hidup Ubur-Ubur di China

Seekor ubur-ubur langka ditemukan di anak sungai China. Ubur-ubur ini dinyatakan sebagai fosil hidup karena seharusnya sudah punah. Seperti apa?

Foto yang diambil pada 27 Juli lalu itu menunjukkan seekor ubur-ubur air tawar di anak sungai di Taishan Mountain di area Tai’an City, timur propinsi Shangdong. Anggota staf Taishan Mountain-lah yang menemukan ubur-ubur air tawar langka ini.

Ubur-ubur air tawar merupakan coelenterate yang sangat tua yang mendekati kepunahan. Ubur-ubur ini telah hidup di Bumi selama 1,5 miliar tahun dan dianggap sebagai fosil hidup.

Ubur-ubur ini hanya bisa hidup di area bebas polusi dengan kadar asam air tawar cukup dengan suhu lebih rendah dari 35 derajat Celcius seperti ditulis Xinhua. [mor]
