What's to prevent the "local meat-based wildlife" from taking a very expensive test bite?

how long before the researchers discover that their £20,000 toy has been eaten by a shark (laser headgear optional) or other predator?

Mine's the one with the greasy newspaper of chips in the pocket...

Honestly, you'd think they'd have better things to do, spending scads of money on this sort of project, probably just to become a dab hand at some new embedded processor the prof fancied the look of. Of course, if they can tuna the software and hardware by spending a few squid I suppose it might work.

It's not my plaice to pout I suppose as most students just flounder around listening to bass tracks or sole music and it's nice to see students with a worthy porpoise but you have to wonder what sort of pollacks they will publish in their paper.

Anonymous, would you put your name to that array of awful piscine puns (I resisted working in hard of herring, damn, no I didn't!)?

Paris, nice kipper.

Oh, how do you stun an octopus?

Kick it in the tentacles!

"Om nom nom nom BLEARGH! Jesus, Bob, forget these things. They're carp!"

Sharks (of which there are many hanging about Biscay looking for the electrical signature of something slow to munch on) can't spell and that's £20,000 down the drain. Never mind ROTM, more like a line of angry sharks suing for Li-Ion burns and false advertising.

I wonder if it will give bigger predators a bit of a tummy ache?

that when I hear the words "hundreds of millions of years' worth of evolution" I imagine them being spoken in the voice of Sam Neill?

I see El Reg's pun development department isn't flounder-ing; it's stilled perch-ed at the top of the pile, wrass-ling humour from the most unlikely sources...

Mine's the one with the trout in its pocket...

About the size of a seal, but looks like a fish. Sounds like the perfect meal for a hungry shark to me... Who wants to place bets on how long before the first one gets eaten?

Shame they didn't paint it green with a pearlescent white eye, because then it look like a seal sized terror fish, Perfect for shooting down with a seal sized Stingray and a Troy Tempest puppet

Errr, Troy, ay think ay got sumthin' !

Stand by for action! We are about to launch Stingray. Anything can happen in the next half hour!

Isn't a 1.5m long carp going to look pretty appetising to whatever it is that eats carp in the local area? Seems quite expensive to end up as shark food.

Let's hope the plucky Spaniards haven't seen Stingray, otherwise they may spot our fish-borne reptilian invasion fleet for what it is!

Altogether now...

STINGRAAYYYYY-STINGRAY!! Dadalada-da-da!!

every time i see this 'fish' it reminds me of the evil guys submarine in stingray

They're lovely, the movement is especially great. I heartily approve of making more of these things for any reason whatsoever.

Do they count towards trawler quotas then?

and the charge time is...

so in reality there will only be a lot less fish actually swimming..

1.5 m fishes.. thats pretty big!

So they are going to live within a 4mile radius of a port... Do they have propellor avoidance systems??

Actually these contain a small, but powerful explosive charge and can spot a Spanish trawler full of illegally caught British fish at 2km..........

(Daily Mail articles can be recycled as humour. Who knew?)

Sub-head of the year so far!

D-cell batteries I'm guessing.

Lookie here, maw. I done fished me up this here metal fish. it's a bigg'n. Sure hope it tastes as good as it looks.
