  • Palau's reefs have been attacked in the past by massive crown of thorns starfish (Acanthaster planci) infestations. Ron Leidich recalled that he removed about 6500 of these starfish from this one particular reef after the el Nino event in 1998. The reefs have recovered, but there are still occasional outbreaks of these coral-consuming invertebrates.

  • This is a Stichaeus grigorjewi, sometimes called a long shanny or northern blenny. It is a deepwater species that resides down to depths of around 300 meters in the Sea of Japan and Sea of Okhotsk. Females come up to shallower water to lay eggs. This fish is edible, but the eggs contain a toxin called dinogunellin, which can cause vomiting, nausea, abdominal pain, diarrhea and other unpleasant symptoms if ingested. There are no recorded cases of deaths from consumption of eggs. As pictured here, the fish repeatedly extended and retracted a long, twisted, multi-pronged tongue-like appendage reminiscent of the lure used by stargazers (Uranoscopidae) to attract prey.

  • A pile of four or five venomous banded sea kraits (Laticauda colubrina) lounging on a shaded ledge located on a vertical rock face just above the splash zone of one of the Rock Islands in Nikko Bay. Sea kraits crawl up on the rocks from the sea to rest and perhaps to lay eggs, though no one has yet found sea krait eggs at any haul out site in Palau. There were several aggregations at this site, comprising perhaps up to 30 individuals in total.

  • One of a tangle of four or five banded sea kraits (Laticauda colubrina) hauled up on a ledge of a vertical rock face. There were several clumps of sea kraits resting on the rocks. It is not clear why the marine reptiles behave in this manner. Though these animals possess power venom, they are generally non-aggressive.
