  • Specimen of the Week 249: the Galago

    By George W G Phillips, on 22 July 2016

    Hello all! George Phillips here, presenting my first specimen of the week: the galago. The specimen you see before you is Demidoff’s dwarf galago (Galago demidoff), an omnivorous, nocturnal bushbaby native to the rainforests and wooded savanna of Central and West Africa. With a hearty abdominal incision for better internal distribution of preservative fluid, this handsome fellow has likely been a valuable addition to the teaching collection at the Grant Museum over the years. On many occasions I’ve witnessed visitors’ delight at this specimen’s majestic stance and slightly alien features.

    Weighing as little as 46 grams with a body length of just ten centimeters, Demidoff’s dwarf galago is the smallest primate found in Africa. (more…)

    What’s the difference between snakes and legless lizards? Specimen of the Week 248

    Slow worms – They don’t have a leg to stand on

    Not all legless reptiles are snakes, like this slow worm which is just one of the many kinds of legless lizards. The complete or near loss of limbs has evolved in lizards a great number of times. Some entire lizard families are legless. Some families contain a few species with tiny vestigial limbs, while the rest are limbless. Some families are mostly “normal” four-limbed species, with limblessness, near limblessness, or two-leggedness having evolved in certain lineages independently. The biggest lizard family – the skinks (of which there are 1500 of mostly leggy species) – has groups that have lost their limbs on numerous occassions in Africa, Europe and Australia. In most cases of legless lizards, some remnant of the hindlimbs is visible, often by the precence of scaly flaps.

    Getting legless

    Leglessness evolves when the legs become a hindrance rather than a help in an animals’ locomotion, and in lizards this is normally to do with burrowing. Essentially lizards have found that it is more effective to “swim” through the soil, pushing their way through little gaps with their heads. If you think about it, this makes sense because lizards’ arms aren’t that close to their snouts, so using them to dig can be a it awkward. This is one also one of the main hypotheses for how and why snakes evolved. Swimming is also a driving factor for losing limbs.

    How do you tell a snake from a legless lizard?*

    Specimen of the Week 244: The historic wax flatworm

    Since its inception in 1828, the Grant Museum of Zoology collections have always been used for teaching.  This continues in the present day and the Museum welcomes students from across UCL for a wide variety of specimen-based practicals, course work and research projects.

    Today we maintain detailed lists of specimens which are used in classes but I’ve often wondered what the early object-based teaching practicals looked like and which specimens were used.

    Fortunately, the Museum has some relevant archives which have identified an extraordinary specimen that had been used in teaching at UCL 130 years ago.  It is not only one of the oldest specimens in the collection, but also one of the most beautiful.

    Take a journey back in time with this week’s Specimen of the Week…

    Specimen of the Week 243 – Dolphin Foetus

    By Rachel H Bray, on 10 June 2016

    1. Unpredictable as usual

    The Grant Museum is a haven for the unexpected. As is often the case with the collection (at least, for me anyway), just when you’re expecting to see an animal that you feel fairly au fait with… the museum presents you with specimens that are: dissected, bisected, exploded, stained, crammed with others in a jar or injected with alizarin. So as a case in point, here is the rinsed skeleton of a dolphin foetus.

    Specimen of the Week 242 – the Marsupial Lion

    By Jack Ashby, on 3 June 2016

    1) Large lion-shaped predators were living in Australia until around 50,000 years ago – lion-shaped, but not lions. This is because there were no wild cat species in Australia*, and up until 3-5000 years ago when the dingo arrived with Polynesian traders, all large Australian mammals were marsupials. One such beast was Thylacoleo carnifex, the “marsupial lion”. Alongside this big predator lived “marsupial rhinos” (diprotodons), giant kangaroos, giant echidnas, “marsupial tapirs” (Palorchestes) and giant wombats (Phascolonus). All in all, Australia used to have much bigger animals than it does now.

    2) It is believed that marsupial lions diverged from the branch of the marsupial tree that led to wombats and koalas. (more…)

    Hello all, Dean Veall here. This week I bring you my specimen of the week. I can imagine what you’re wondering… has Dean chosen some sticks from the highly popular children’s game Ker-plunk? Has the acquisitions policy at the Grant Museum gone out the window? Well look closer dear reader, and you will see that these are in fact quills from a porcupine!
