its strange that alot of aberrant forms exist in tigris as well as a few other specie. Why do you think is the specie has a higher incidence of deformity?

There have been a few publications on these freaks from Zanzibar. Most of them come from the westcoast.
But the authors speculate about what causes these extreme
rostration (pollution???) Anyhow...most of them have a double weight when compared with normal specimens of the same size...I agree: I can show you tigris which look like "rocks"...

Dear Michael, I have photographed the Cypraea tigris L which looks like a rock. As you can see; it is even rough on top and you have to turn it around to see that is a shell.
According to my contacts in Zanzibar the shell was live-collected! It is extremely heavy and measures 91mm. To be frank...this is not nice anymore...I am a shellcollector and this more of a rock at first glance...

I agree...the shell was sent to me from Zanzibar. It is the poorest tigris I have ever seen.

Hard to say...as I did not collect it myself. My contacts overthere say that only in certain areas at the westcoast of Zanzibar these freaks occur...
There has to be a cause... They think it has to do with pollution in the area.

I have added three other freak-specimens. Two of them have a dorsal line.

I wonder how old these fellows got. The tigris in the Frankfurt aquarium are 25 years old and just begin to show a bit of blistery line middorsally. I once cut such a freak from Zanzibar and counted 220 layers of enamel...!
