The pictures from our friend in Kwajalein keep rolling in. As he explores the islands and gets more comfortable with his surroundings, new areas are getting explored. This update is focused on one of my favorite aquarium invertebrates, Tridacna clams. Both T. crocea and T. maxima clams can be seen in tidepools. The clams are burrowed into the substrate and some are even exposed at low tide. The clams of course are used to being exposed at low tides, so this isn’t an issue so long as the tide returns within a few hours. To stay wet, the clams close up and keep as much seawater in their shell and tissues.
