Here are some images from another ROV taken in the Gulf of an
unidentified jelly. It looks like this might be the mystery jelly
from the video. Anyone have a positive ID on this species?

Definitely a jelly of some
sort. If you know the speed of the ROV
decent and the diameter of the pipe, it should be possible to
calculate the size of the critter by determining its distance in
front of the pipe. This can be done by measuring the movement up the
image frame of the pipe compared to the head of the jelly.
However I am not competent to do that math. I would say it is a
jelly, but not monstrous. Is should be possible to model it in 3D if
you have the camera's lens angle of view. Then Match the images up
get a size. You could also use Matchmove software to analyze
There is an inexpensive program with a free trial called PFHoe
This might be able to define the spacial relation ships and export
the results to a 3D package for analysis.
This may be a little easier for
The video was captured from an ROV in the Gulf of Mexico at 3,540
I need some assistance identifying a marine organism. My
brother-in-law captains a ship in the Gulf of Mexico and their ROV
recorded video of an unidentified marine organism. Some
that they've seen a giant squid and others think its a large
species of jellyfish. The pipe in the middle of the video is a
marine riser and is 36" in diameter. If you check the left
of the screen you'll see it swim upward past the riser as the ROV
slowly pans down. It's tough to estimate size though because
they're not sure exactly how close they were to the riser. The
ROV descends approximately 25' during the clip. Some estimate
creature to be 75-100' in length.
Any assistance, guesses, or thoughts would be appreciated.
