Achatina margenata - the West African species


That sliming snail again!

Pac-Man the snailMagnifying glass

On 7th September 1997 I went to Zoologica '97, a pet exhibition with an emphasis on exotics, at the Ardingly Showground, in England. I went with the intention of buying a book on Giant African Land Snails and some tortoise food ..... as is usual with my shopping trips, I didn't get what I went out for - what I did return with was something completely different - three A. marginata (now called Cyclops, Pac-Man and Atlas, BTW!!) and a new tank!

I have a feeling that the three I brought had been taken from the wild (the guy who sold them to me did tell me where they came from, but I forgot - duhh!!). I didn't realise this until I got them home, and eventually managed to get them out of their shells - they were very dehydrated, and their bodies were covered in scars and healing cuts. One of them (Cyclops, obviously!) only had one eye - only I could buy a one-eyed snail! :D - and showed evidence of cuts around the base of both eyestalks (he has a stump!). Whether these were caused by a predator in the wild, or man made, is anyone's guess. The scars and cuts are all healing nicely now, and fading rapidly. The shells are looking better, and the only marks they'll be left with seem to be the gaps where chunks have been taken out of the edge of the 'foot' . It took over a week to get them eating (and indeed having 'bowel movements') properly. They now devour the cuttlefish with vigor!

They're very shy, and I really only get to see a good view of them just as I'm about to go off to bed (guess they must have been nocturnal in the wild!). I have had 7 eggs from them (on Boxing Day 1997) though. Unfortunately only one hatched, now called "Little It". They only lay around six eggs, of about 15 mm (OUCH!!), compared to the hundreds of 4-5 mm eggs that A. fulica lay. I'm still working on breeding them properly, so I've set up a record of the successes and failures. I have also typed up an abridged version of a research paper on breeding margies.

When comparing the two species, the first thing you notice is the size difference. The A. marginata I have at present are around 150 mm in shell length, while Herc is about 95 mm (I've no idea how big they grow - doubt they'll get much bigger though!). The next major difference is the shell markings - the A. fulica seem to be a greeny brown or mahogany colour (I know Herc looks orange in his photo! :) - the A. marginata are brown, with dark brown stripes. They also have very obvious pink tips to the ends of their shells - though I've recently - Dec '99 - received some new margies whose shells do not have the destinctive pink tip:


See the difference in apex colour?

though they still have the very obvious 'blunt' look to the apex!), and the inside lip of the shell is bright pink, whereas A. fulica's is white. The shell also feels more like the kind of shell you'd find on a beach, as opposed to the normal 'delicate' snail's shell. It is also more rounded, as opposed to the very sharp, pointy shell of A. fulica. These pictures show quite well the difference between A. fulica, A. marginata and A. achatina.

Looking at the actual snail, they are again, very obviously bigger! In fact, they are scary snails!! :-D The main trunk of the body is thicker than my thumb. My original margies and babies are dark grey in colour, though my new snails are a beautiful light 'coffee' colour, as this picture shows:

One of my babies (bottom) and one of the new arrivals (top). Note the colour differences.

All my A. fulica are various shades of light brown, with the exception of Herc, who is a kind of dark brown/grey colour! Their skin also seems to be a lot thicker than the soft, dainty A. fulica. When fully extended, these things have eyestalks of around 2 inches, and can eat a soaked pellet of tortoise food in one bite (that's how Pac-Man got his name :-) Also, if you look at the tail of the actual snail, you notice that the margies seem to have a pattern on their tail - a kind of serrated V shape - very pretty!

Ohh, I'll 'ave a bit of that!Magnifying glass
Ok then, maybe I *will* have a bit of that!

They are very strong snails (built like little tanks!!) - as they are so shy I brought them a plant pot to hide in (one of the type meant to go on a wall - ie with one flat side and one rounded side - like a little cave!) - they hid under it!! Now I've got them a cork bark tunnel which they love, but I've given up trying to landscape the cage - whatever I do, the buggers have trashed it all by the next morning! :-D
