Can anyone ID a short story (I think) from the 1950s/60s/70s about an expedition to a planet which is mainly water on the surface. One of the human visitors sees, below him in the water, something threatening like a yellow hammerhead shark. Possibly by Ray Bradbury, possibly published in the Gollancz hardback science fiction series?

  • This is a brief but detailed description of the story. Can you remember anything else that happens in the story you could edit in? Every little detail you add can help others identify this for yourself.

  • Sadly I probably read this fifty (fifty! argh!) years ago, and I can't dredge up anything else. If anything else surfaces I'll certainly add it - thanks for asking though. Commented Nov 20, 2019 at 18:22
  • There's a Jack Vance novel that partially matches this, but it isn't about an expedition to an ocean planet, but rather people who live in floating settlements on it.

  • Thank you Spencer. I wouldn't rule it out ... I suppose if you remembered what it was called, you would have named it ... ? Commented Nov 23, 2019 at 16:00
  • Maybe "Grandpa" by James H. Schmitz, online at web.archive.org/web/20150826151128/http://www.baenebooks.com:80/… ? The protagonist is on a "raft": a lily-pad-like life-form. At one point, he sees a white shark-like predator; his raft is also hijacked by a "Yellowhead". Maybe those together make you remember a yellow (hammer)head shark? But the planet is not all water, although the sea is where the action is. And not Bradbury's style. In Spectrum V, which did come in Gollancz hardback. Are there enough matches for me to put this as an answer? Commented Jul 25, 2020 at 17:40

1 Answer 1


"Grandpa", by James H. Schmitz. Originally published in Astounding Science Fiction, February 1955. As mentioned in my comment above, an online copy is available at https://web.archive.org/web/20150826151128/http://www.baenebooks.com:80/10.1125/Baen/0671319841/0671319841___2.htm .

It's been anthologised in numerous places, and I've seen it so many times, which is how I found it. I have in front of me a copy of Spectrum V with it in. But equally well-known, in the UK anyway, would have been Penguin Science Fiction, which also republished it.

As you've confirmed that this is the story, I'm answering just for the record. After some delay, because of problems with my Internet connection.

A short story (I think) from the 1950s/60s/70s:

Original publication year 1955, but the impressive list of republications shows a new appearance almost every year up to 1990, and a few after 2000 as well. Some of these are merely new editions, but even so, it keeps on and on coming back.

An expedition to a planet which is mainly water on the surface:

"Expedition" is perhaps an understatement: "The Colonial Team was a practical, hard-working outfit—two thousand people who'd been given twenty years to size up and tame down the brand-new world of Sutang to the point where a huundred thousand colonists could be settled on it, in reasonable safety and comfort."

The planet isn't just water. For example, the station manager Nirmond complains about the protagonist Cord keeping "unidentified and possibly deadly vermin in the woods back of the station". But most of the action does take place on water. On page 3, Nirmond drives Cord and others down to the edge of the bay in a treadcar, and they stop at the edge of a marshy cove, from which they transfer to a "raft". These are organisms that look like "lily pads twenty-five feet across". The raft they take is called Grandpa, a "regular monster" at fifty feet across.

One of the human visitors sees, below him in the water, something threatening like a yellow hammerhead shark:

"The reed bed to their right was thick with Yellowheads, a colony of them. Vaguely froggy things, man-sized and better. Of all the creatures he'd discovered in the bay, Cord liked them least. The flabby, sacklike bodies clung with four thin limbs to the upper sections of the twenty-foot reeds that lined the channel. They hardly ever moved, but their huge bulging eyes seemed to take in everything that went on about them. Every so often, a downy swamp bug came close enough; and a Yellowhead would open its vertical, enormous, tooth-lined slash of a mouth, extend the whole front of its face like a bellows in a flashing strike; and the bug would be gone. They might be useful, but Cord hated them."

Or, later on and with a different predator: "It was the shattering of his [Cord's] hopes to swim to shore from here. Fifty yards away, the creature from which the rubbery thing had been fleeing showed briefly on the surface, as it turned away from the raft; and that glance was all he needed. The ivory-white body and gaping jaws were similar enough to those of the sharks of Earth to indicate the pursuer's nature. The important difference was that wherever the White Hunters of the Zlanti Deep went, they went by the thousands."

  • Thank you, Phil. Interesting to know the story was such a popular anthology choice. Very inventive, and some highly memorable images. Commented Sep 11, 2020 at 11:39
