Reports

Jeannette & Scott Johnson about Terestrombus fragilis from Kwajalein Atoll:

  • "Terestrombus fragilis is uncommonly seen alive, but it must at times be quite common in some areas. When parts of the lagoon bottom at Kwajalein were dredged some years ago to extend the island, many T. fragilis shells were dredged along with the sand and rubble. Empty shells are also often seen on deep lagoon shipwrecks, so they may be more common in the deeper lagoon. Nowadays, we see them in lagoon Halimeda beds and also in piles of rubble along the lagoon reef from about 3m on down. They seem to not occur on the seaward reef at all. Shells range up to about 49mm in length."
