In a US Navy Hu-16 Albatross seaplane we flew from Guam to Truk then Kapingamarangi and later Nukuoro (not shown on map) before returning via Truk and Guam. An exciting adventure.
Our survey of reefs at these two atolls only found small numbers of starfish in the lagoon.
The starfish continues to be a real problem on parts of the Great Barrier Reef. The above pictures show a giant starfish, perhaps 200 years old. The location was close to a popular tourist destination on the southern part of the GBR, in Australia (1988).
