Ahli biologi kelautan merasa heran setelah melihat rekaman yang memperlihatkan mahluk bergerak-gerak seperti cairan atau kain tipis di bawah laut. Rekaman ini pun kemudian jadi populer di internet.
Para pengebor bawah laut merekam gambar ini menggunakan kamera laut dalam yang dikendalikan jarak jauh. Video ini menangkap sesuatu berwarna seperti susu dan berbentuk misterius bergerak-gerak dekat sumur minyak bawah laut, sekitar 1524 meter di bawah permukaan laut.
Pada akhir video ini, mahluk berbentuk aneh ini tiba-tiba turun. Bahkan ahli dari Asosiasi Biologi Kelautan (Marine Biology Association - MBA) Inggris atau Pusat Oseanografi Nasional di Southampton tahu apa mahluk ini sebenarnya.
Kepala ahli akuaris John Rundle mengatakan pada Yahoo! News, "Tampaknya seperti semacam ubur-ubur, tapi kami tidak dapat menyimpulkannya."
Ada juga kemungkinan bahwa mahluk ini adalah semacam monster dari laut dalam. Yang lain berspekulasi bahwa ini bisa jadi plasenta paus.
Teori yang paling umum di antara para komentator adalah mahluk ini semacam ubur-ubur bernama Deepstaria enigmatica - tetapi organ dan bagian tubuh luar mahluk ini membuatnya sangat unik, bahkan di antara ubur-ubur.
Mahluk tak bertulang belakang ini biasanya ditemukan di selatan Atlantik, pertama ditemukan pada 1967 dan bisa mencapai diameter 60 cm.
Menurut Anda mahluk apa ini?
Unidentified floating object: Mysterious blob filmed in the deep - and no-one can work out what it could be
YouTube video leaves commentators baffled
Creature could be a jellyfish - but it appears to have organs
It could be a discarded whale placenta - but it has strange markings
It could be a fishing net - but it seems to move under its own control
A mysterious ocean 'blob' has been recorded by a deep-sea remote-controlled underwater camera.
The creature looks like nothing seen before, with speculators suggesting it is everything from a jellyfish to the remains of a whale placenta.
While, at a quick glance, the description of a jellyfish makes sense, the creature has organs and appendages never spotted on a jellyfish before.
Meanwhile it could be a whale placenta, but if that is the case then the hexagonal shapes on the skin are a mystery.
If it is a jellyfish, it might be a Stygiomedusa Gigantea. This type of jellyfish - which can grow up to six metres in length - has only been spotted 114 times in 110 years, so details on it are scant.
But again, the appendages get in the way.
------------------------------------------
Another suggestion is Deepstaria Enigmatica, another rarely-studied jellyfish, which like most of its kind is colourless.
However it has reported to have a brown stomach, with one description saying the passages to the stomach are 'somewhat irregular-edged, forming a reticulate network'.
This might explain the hexagonal markings on the top of the creature - but again, what are the organs doing there?
Those markings lead one commentator on the website Snopes - which tries to debunk or confirm rumours - to suggest this is simply nothing more than a fishing net.
But again, the appendages get in the way.
Another mystery - a man-made one, this time - is exactly where this video was filmed. It was added to YouTube on April 27 this year, and appears to have been filmed two days earlier, but the poster did not leave any other details about the sighting.
sesungguhnya..kita manusia,ilmu kita sgt lah sedikit...masih byk yg perlu diteroka..itu pon masih ada yg berlagak melebihi Allah,bru ni aku layan youtube tgok semula debat Islam dgn Chistian & Yahudi...dah ada bukti kenyataan dia masih jgk degil..bila dunia menjadi Tuhan mereka apa yg mmpu ku katakan lagi
