Kecoh makhluk ganjil di tasik


GAMBAR yang dihantar ke Institut Sains Marin Virginia menunjukkan bentuk hidupan air yang mencetuskan kekecohan di Newport News baru-baru ini.


RICHMOND, Amerika Syarikat (AS) - Beberapa orang menemui satu benda ganjil yang besar dan bertompok-tompok terapung di sebuah tasik buatan di Oyster Point, bandar Newport News, Virginia, lapor sebuah akhbar kelmarin.

Pada mulanya, benda ganjil itu ditemui oleh seorang pekerja pejabat, Tracy Collier semasa membawa seekor anjing milik bosnya berjalan.

Dia dan beberapa pekerja pejabat lain kemudian menghubungi pakar-pakar di Institut Sains Marin Virginia dengan menghantar e-mel dan gambar makhluk itu.

Makhluk itu berdiameter kira-kira 1.21 meter dan bergerak ke dalam tasik sejauh 1.82 meter.

Ia kelihatan bergoyang semasa gelombang ombak membadai makhluk ganjil itu.

Pakar-pakar di institut tersebut menjelaskan bahawa makhluk ganjil itu merupakan koloni hidupan airPectinatella magnifica.

Koloni hidupan air itu muncul sama ada terapung atau berpaut pada objek terapung. - Agensi

Pectinatella magnifica


BryozoanThis is the Pectinatella magnifica specimen which you were viewing. The following pictures are close-ups of its surface and internal jelly, taken just to the right of its break.

BryozoanP. magnifica has a clear, golden-tan jelly which is covered by the actual colony. Each of the small clusters in this close-up contains hundreds of the individual-animal lophophores.

BryozoanEven this closer view doesn't show the individual lophophores.

BryozoanThis view shows a little of that outer crust, but focusses on the internal jelly. The central detail is the broken end of its once-supporting twig. The jelly harbors a type of non-biting midge larvae, and appears to be a favored food for raccoons. (For technical information on the composition of this jelly, see 29 Sep 1997 message from Byron Backus.)
