Concerning message #22783:

Dear Bill.

I understand you regret there are too few photographs of Alderia modesta on the Forum. So I am sending you some recent photographs of Alderia modesta [message #22841] and Limapontia depressa taken in the field (on the saltmarshes in the south-west part of our country near estuarine coastal waters). I regularly find both species throughout the year, exept in periods when it is very cold or dry.

The animals mostly are very small in size: 2 - 3 mm and they live on Vaucheria spec.

Locality: saltmarshes in the south-west part of the country near estuarine, coastal waters, / on saltmarshes, the Netherlands, estuarine waters of the North Sea, autumn 2008, on saltmarshes on Vaucheria spec.. Length: 2 - 3 mm. Photographer: Marianne Ligthart.

With greetings:
Marianne Ligthart

Dear Marianne,

Thanks for this photo of Limapontia depressa 'at home'. We can clearly see the branching green digestive gland through the semi-transparent skin which we discussed in earlier messages.

Best wishes,
Bill Rudman
