Oh My Marlin’

Sperm whales weren’t the only thing we saw in Ogasawara.

We came across two species of dolphins (Tursiops aduncus and Stenella attenuata), as well as a family of Cuvier’s beaked whales (Ziphius cavirostris…I came oh so very tantalisingly close to getting in-water photos of them!).

We also rescued a baby Bulwer’s petrel (Bulweria bulwerii) that might have left the safety of its nest too soon. It was adrift in the water, unable to fly. Three of us managed to surround it, allowing me to grab hold of the frightened bird and take it back to land to be nursed to health and set free a few days later.

The most adrenaline-inducing non-sperm whale encounters, however, were with two large marlins that buzzed us at close quarters on two separate occasions…both times while we were preoccupied with large cetaceans.

This one was probably around two to two-and-a-half metres long (without the pointy part):

I’ve gone for years without ever seeing a marlin in the water, and now I’ve seen three in the past three months: one in Tonga, and two in Ogasawara.

By the way, does anyone know what kind of marlin this is? The local fishermen suggested that the fish were either striped or blue marlins.

    Tony,

    My last incoming e-mail from you was dated Sep 26…….Did I miss a change re: how you would communicate with us? I can find later posts by looking at earlier ones. Please let me know. Thanx.

    Based on the height of the dorsal fin I think this is a blue marlin. The National Audubon Society Field Guide to Fishes says the striped marlin’s first dorsal fin has a “anterior height equal to or greater than body depth” and also says its “Pelvic fin [is] much longer than pectoral fin” and neither seems to be the case with this animal. Photos seem to show the blue marlin with a stockier body (like this guy), while the striped marlin seems to be much leaner.

    Thank you Gina!

    Tony,
    from a photographer specialized in taking stills of large blue marlin I can say with 100 % certainty that this is Pacific blue marlin.
    The marlin must have been feeding, usually they cruise in deeper water w/ their dorsal down. Only when looking for food they pop up the dorsal and become lit-up (note the tail being very bright).
    Is this a crop?
    Best,
    Daniel

    Hi Daniel,

    Thanks for the confirmation! Slight crop. The second one snuck up from behind and passed within about two metres from me. Quite a sight!

    Both marlin encounters were when we were in the water with sperm whales that had come up from feeding. Is it possible that they were looking for squid scraps?

    Cheers,

    Tony

    Tony-
    I’m not sure about the squid scraps, my theory would rather be, that the squid scraps, skin tissue etc. attract smaller fish (e.g. dolphin fish, trigger fish), those do then attract the marlin. I’m pretty sure a pod of sperm whales acts as a fish aggregating device.
    The fact that the marlin were close to the surface means they have been feeding. Blue marlin cruise at a depth of ca. 50 meters where there are neutrally buoyant.
    I once took images of a loggerhead seaturtle in the epi-pelagics of the Azores, when in my back a white marlin and a few seconds later a ca. 550 blue marlin appeared… I dropped the turtle and took pics of the big marlin.
    Cheers,
    Daniel

    Hi Daniel,

    Ok, that makes sense. The marlins were quite shy after their first passes. I wish they had been more inquisitive so I could’ve had more photo opportunities. But nothing is ever that easy, right?

    Cheers,

    Tony

    Yeap Tony,
    taking pics of them is really tricky. They are inquisitive but shy and spooky at the same time. I had one lucky encounter last year: a blue marlin circled around me for over 3 minutes! This is very unusual.
    I love them, they are so beautiful.
    Cheers,
    Daniel
