Manta Ray?

Posted by James, Thursday, 14th July 2005

Is this dark grey triangle off the coast of Rio de Janeiro a giant Manta Ray? They can apparently grow up to 8 metres wide, so if a Manta Ray was swimming near the surface we might be able to see something at the maximum zoom level. Any sealife experts willing to prove it one way or the other?

    Could it be Mola mola?

  2. 2. Shea says:

    Whaaaaaaaaaaa? Manta Ray? Eeeeeeeek!

  3. 3. Keith says:

    It’s size is similar to some of the houses along the beach to the north (if not bigger), which would make it quite large.

  4. 4. Silus Grok says:

    I thought it might be a sun fish (http://en.wikipedia.org/wiki/Ocean_sunfish), but they only get to 13 at the largest.

    * crosses fingers *

    But I love mantas… and that would be just super if this were one.

  5. 5. Kyle French says:

    Well they can get quite big as seen in this pic: http://www.ukdivers.net/life/rs/manta_ray.jpg
    Nice find.

  6. 6. APG says:

    Its apparent size, measured with Google Earth is about 1m x 2.1m, and it’s not regular (the east side is longer than the west one). Of course, these are just apparent measures, the real size being dependant on the depth where this thing is.

  7. 7. Jeff Alu says:

    I just measured (via Google Earth) and this baby has a “wingspan” of 20 meters. Also, zooming in and taking up the saturation reveals some unlikely Manta coloration (could be artifacts…)

    So my guess is rock with green plants or perhaps a creature from the movie “The Abyss”

    But with green lights instead of pink.

    I’ve never heards of these animals around here in Rio. Being off the coast of Rio it’s probably just pollution. 8-)

  9. 9. Jacob Tomaw says:

    APG,

    Don’t you mean more like 10m x 20m? That is what I measure in gEarth.

  10. 10. Winterfresh says:

    APG… What google earth are YOU using? Mine says it’s 16m x 10m.

  11. 11. mikster says:

    Water is like a magnifying glass… it might appear larger than it actually is.

  12. 12. David Oranchak says:

    Couldn’t it be just a wisp of cloud? If you scroll to the left you can see other clouds.

  13. 13. Chris Gabriel says:

    Wikipedia says “Mantas are most commonly black above and white below, but some are blue on their backs.”

    I’d say its too light/grayish to be that.

    Perhaps its a rock below the surface? (Below, seeing as the surface water doesn’t seem to be disturbed by it at all)

  14. 14. Jared says:

    I bet it’s Phoenix. (X-men 2)

  15. 15. GoogleSightseer says:

    Those “clouds” are not really clouds. It is water crashing against the rocks, making white caps.

  16. 16. Keith T. says:

    Take a screencap of that section, increase the gamma in a photo editor, and you’ll notice there don’t seem to be any ripples caused from waves hitting the triangle. So it’s almost certainly below water.

    There does seem to be a curving trail coming from behind it that curves around rightward towards the north. It seems to me that could be the resulting ripples of something swimming just below the close-to-surface. On the other hand, it might also be a reef.

  17. 17. Tim says:

    I think it’s a cloud.

  18. 18. aaron says:

    I think it’s one of these:

    Come on guys, its obvious to me that is a picture of the Flying-Sub from The Seaview.

    I’d love it to be a Manta - but I’m pessimistic. I’ve seen quite a lot of small Manta Rays at Placemark: South Stradbroke Island / Google Earth in Australia and they’re always very dark (black) above. Against water this colour, they would be invisible.
    There are some unusual artefacts (whisps?) around the area, but none look as solid as this. It also seems to have some 3d form. IMHO it’s not a rock - the water looks quite deep, not a cloud - too solid, the ‘trail’ is a furphy - there are many in the area, most likely surface scum in ‘wind lanes’ caused by inconsistent wind patterns (ask any fisherman!).

    Worth considering the possibility that this object is well above the water. Take the nearby rocks as an example - it’s almost impossible to see any features below the surface although there must be some shallow points. Also, for a reality check, compare sizes with this Placemark: small boat / Google Earth and another one in the lee of the rocks further south. It makes it one VERY big ray!

    If it’s a living thing, it’s a whale.

  22. 22. APG says:

    Ouups! Sorry for the forgotten zeros, please read 10 x 20 (instead of 1 x 2)

  23. 23. Birdman of Malkatraz says:

    I think God left a rock there on Porpoise

  24. 24. Yorgle says:

    I think it’s a ketchup farm that is either not ripe yet, or overripe.

  25. 25. Patrick says:

    I think I have found what could be……uhm, whales, sea serpents, I dunno!!!….there are rocks and lots of strange grey wisps in the water, scroll around…….and this is off the coast of Nova Scotia where whales are plentiful….and yes this is “hole-in-the-coast” Patrick :-)

  26. 26. Birdman of Malkatraz says:

    that’s pretty odd that is - notice the circular nature of the water too - like fanning out around that white splash - crazeh!

    *hits the bong*

  27. 27. CaffeineJunkie says:

    Hey has anyone found any whirlpools yet?

  28. 28. some young guy says:

    on patricks link there is a whirlpool i think. scroll down a tiny bit and to the right.

  29. 29. Luciano A. Ferrer says:

    Sorry guys… but it’s… me!

  30. 30. Dave says:

    Light that passes through water loses its red component–see the blue wash around those rocks? If this thing were underwater, it’d be blue, not grey..

  31. 31. Keith T. says:

    Could it be a power glider? That might explain the size as well as the trail coming from it (it could be smoke).

  32. 32. Aaron says:

    Patrick, if you look around, especially to the north where the hi-res comes back, there are things doing that that are almost certainly not whales.

  33. 33. Don S says:

    I’m thinking along the same lines as Keith T. - it’s some kind of hang glider.

  34. 34. Dave says:

    A hang glider two miles from shore? No chance. It’s just a wisp of cloud, or maybe the wash from a random breaker.

  35. 35. Callum says:

    I don’t believe for a second we can find the answers to everything on Google. File this one under “unexplanable”.
