Guam Micro Samples



This specimens were found at Pago Beach on the island of Guam. Images are magnified 40 times under a microscope which should equate to a 4 mm field of view. The first picture has a gastropod in it. The other specimens might be some sort of foraminifera.

Thanks to Pam for obtaining the specimen and Herb for the processed material.

Hi, Mike--

Nice photos! The pointy objects in photos 1 and 3 are spicules or sclerites, probably from octocorals (soft corals). See for example http://www.dnr.sc.gov/marine/sertc/octocoral%20guide/Scleracis_guadalupensis.htm
These are quite common in biogenic tropical sands; some types are purple or red, and quite attractive.
Photo 2 is Amphistegina, a foram.
