Tentacle is the Newsletter of the Mollusc Specialist Group of the Species Survival Commission of the IUCN (International Union for Conservation of Nature).

If you plan to submit an article to Tentacle


This will make the lives of the editorial team a lot easier


Your submission must be relevant to mollusc conservation


I usually make only editorial changes to submitted articles and in the past have accepted almost everything sent to me. However, before I accept an article I will assess whether it really includes anything explicitly relevant to mollusc conservation and whether any conclusions drawn are supported by the information presented. For example, new records of non-native species will not be accepted unless there is a clear and significant relevance to mollusc conservation. First records of invasive species are better submitted to the journal Bioinvasions Records, which focusses explicitly on such reports. So, fully explain the conservation relevance in your article and be sure not to speculate too wildly. Unjustified statements (even if probably true) do a disservice to conservation as they permit our critics to undermine our overall arguments. Tentacle, however, is not a peer-reviewed publication and statements made in Tentacle remain the authors’ responsibilities.


I stress that Tentacle is not a peer-reviewed scholarly scientific journal. Please do not see Tentacle as an easy way to get your original data published without going through the rigours of peer review. Tentacle is a newsletter and so it is primarily news items that I want, including summaries of your ongoing studies, rather than full, data-rich reports of your research. Those reports should be submitted to peer reviewed journals. I will increasingly decline to publish articles that I feel should be in the peer-reviewed literature, especially if they are long.


Therefore, there is a limit of three published pages, including all text, illustrations, references, etc., for all articles that I accept for publication in Tentacle (though I reserve the right to make rare exceptions if I consider it appropriate).


Please make every effort to format your article, including fonts (Times New Roman), paragraphing styles, heading styles, and especially citations, in a way that makes it easy for me simply to paste your article into Tentacle, which is created in Microsoft Word. Please pay special attention to the format (paragraphing, fonts, etc.) in past issues. Conformance to the guidelines has improved – perhaps because of my many many reminders! But it still takes many many hours to format your submissions – please do it for us! Especially, please pay very careful attention to the format of references in the reference lists – it still takes inordinate amounts of time deleting commas, inserting colons, changing journal titles to italics, putting initials after not before names, deleting parentheses around dates and so on. Here are examples of how it should be done – please follow them very carefully:

Also note that all illustrations must fit in a single column, so make sure your maps and diagrams are readable and show what you intend when they are reduced to this size.


Tentacle is published once each year, generally in January. I usually set 31 December as the deadline for submissions, but feel free to send me contributions at any time and I will hold them until the next issue.
