Radiolarian Skeleton

Description:

Though it was just a skeleton, it was one of the more interesting finds in this sample and I only found one. Probably more than 95% of the plankton we observed in this sample were phytoplankton, so finding some zooplankton was also interesting. The skeletons of most radiolarians are made of silica or strontium sulfate, and are these skeletons are actually a common sediment on the sea floor.

Habitat:

A marine biologist on board skimmed some plankton using really fine mesh nets and we took a drop from that sample and placed it under a microscope. The sample was skimmed in Izhut Bay just off Afognak Island in somewhat shallow water (less than 200 feet).
