Friday mystery object #86

This week I thought it would be nice to give you a bit of a break from the usual skulls, so this week I have a fluid preserved specimen for you to identify:

It may just look like a small white blob, but it’s my favourite small white blob ever. Can you work out what it is?

As usual you can put your observations, comments and suggestions below and I’ll do my best to respond. Good luck!

    • Not necessarily. We preserve vertebrates in fluid too if we want to see their soft tissue. There are also often preparations to show life-cycles, internal organs etc. So Paolo’s white blob really could be anything!

    • It certainly looks similar to some of the delectables from the Tapas (it’s certainly non-vegetarian), but if they served this up I would probably call the Police…

  1. My inital feeling was cephalopod, but would that really be your “favourite small white blob ever”? Not convinced.

    So I’m going to go slightly more left-field, suggest it’s somethign embryonic where the flesh has not been well preserved, and have a massive stab in the dark. Whale.

  2. Is it an entire organism? Or just part of one?
    I’m looking to the left of the jar, and wondering what I’m looking at there, which makes me think…

  3. Something about its paleness makes me think of a tapeworm, which puts me in mind of “a ghastly parasite of some sort” (to use all zoological jargon), but the shape seems all wrong for that; it’s fat and bulbous rather than coiled and thin.

    • Most things in jars of alcohol tend to end up pale, so don’t let the colour distract you. This isn’t really a parasite (although I suppose you could consider it to be a parasite of sorts in the stage of life that this one has been preserved at).

  4. As you say, the colour doesn’t mean much if its preserved in alcohol. Neither does the rather rugose nature of the thing – alcohol isn’t great for that sort of preservation. The clues you’ve given so far lead me to believe we’re looking at something foetal and vertebrate, so my guess would be that the main thing we can see is the placenta.

    Now… bottom left hand corner – would that be a head and paw I can see, or just a trick of the light? My guess is the former, which makes sense if we’re largely looking at placenta. Difficult to say what animal it is, but obviously something pretty small. A rodent, perhaps?

    • You’re right about it being foetal and vertebrate, but there’s no placenta present – it’s all embryo. Don’t forget that it’s an embryo, so the size will depend on the degree of development!

  5. Huh. Knowing it’s an embryo give me some idea (possibly incorrect) of the orientation: tail and hind-limbs at top, trunk, then forelimbs at lower left and the head, unhelpfully facing away from us, at lower right. It would then appear to be a quadrapedal tetrapod, probably (?) a mammal. Based on the apparent shape of the feet and possibly the hint of an ear I’m going to say …
