When the language of biology meets common parlance there’s often a lot of confusion. Biological nomenclature (often called the scientific name, we are Homo sapiens sapiens* for example)  is by and large controlled using strict rules, format and notations but there aren’t quite so strict rules when it comes to the common names of animals or groups of animals. Some animals we refer to by their taxonomic name, for example; Tyrannosaurus rex, Hippopotamus, Octopus** and Bison. For other animals however, their common, useful to most people and widely understood names create all kinds of problems for the pedantic as I’ve written about before when is comes to sea stars vs starfish. My colleague Jack Ashby wrote about when it comes to seals and sea lions. Consider also that a musk ox is a goat-antelope, horseshoe crabs aren’t crabs at all and the Grant Museum favourite: flying lemurs aren’t and don’t.

The idea of ‘true’ and ‘false’ animals can also be misleading and a lot of pub discussions/arguments/bets come from animals which aren’t what they are often called or even named. How do some animals end up as the ‘true’ and ‘false’ versions of their group. Let’s have a look at some ‘true’ animals and see how the philosophical concepts of truth has ended up in our zoological lexicons.

Back in October, I introduced this series (here’s a link to the opening post) about the specimens you’re near guaranteed to see in every natural history museum. We’ll take each specimen in turn and have a look at why they’re a usual suspect for display in a natural history museum.

Legs like pegs, it’s Japanese spider crab. One down, 8 to go.

The first specimen we’re going to take a look at is the Japanese spider crab. Japanese spider crabs are just one species, Macrocheira kaempferi. Confusingly, there is also a group of crabs, the family Majidae, called spider crabs which doesn’t include the most famous spider crab of them all. Japanese spider crabs are mostly found in coastal waters of southern Japan and have been recorded in waters as deep as 600 m so why do we find them in museums all over the world?

Seven blogs away from the big 1-0-0! In the run up to the 100th blog I am going to bring to you the top ten specimens at the Grant Museum, as voted for by…. me. I have employed strict criteria with which to segregate the top ten from the other 67,990 specimens that we have in our care…

1) It must not be on permanent display, giving you a little behind-the-scenes magic, if you will, as the specimen will then go on display for the week of which it has been named ‘Specimen’. Oh yes. That’s almost as good as our exhibition It Came From The Stores. Almost.

2) It must have at some point in the past made me say ‘woooo’ out loud (given my childlike disposition for expressing wonderment at the world at large, this is not necessarily a hard qualification for the specimen to achieve)

3) I must know (at least in a vague sort of a way) what species the specimen is, as SotW is researched and written within a strict one hour time frame.

With that in mind, at Number Eight, this week’s Specimen of the Week is… (more…)
