Subgenus StauroporaObserver
wendy5Description
This 4" Holothuria pervicax (Stubborn Sea Cucumber) has thicker defensive sticky threads than its relative, the Holothuria leucospilota (black sea cucumber). And these are pale blue instead of white. Thanks to naturalist Ian Hutton for the explanation!

Black Sea Cucumber (Holothuria leucospilota)Observer
wendy5Description
This 12" Holothuria leucospilota (black sea cucumber) demonstrates how it expels thin, sticky defensive threads to confuse its predator. The predator would become entangled in the gummy threads, and the cucumber could escape. Many thanks to naturalist Ian Hutton for showing me this phenomenon.

Missing LocationDescription
Glad to find a commercially exploited, endangered sea cucumber (and it was big). Of course it has to stay where it is....

Round-mouth Bean Urchin (Echinoneus cyclostomus)Observer
wendy5Description
This small, oval Echinoneus cyclostomus (Round-mouth Bean Urchin-- great name!) measured a little over an inch long, and a bit less wide, with short red spines. It's not very common at all, and this is the only live one I saw at Lord Howe Island. Thanks to naturalist Ian Hutton for finding it!

Lollyfish Sea Cucumber (Holothuria atra)Observer
wendy5Description
This Holothuria atra (sea cucumber), 14” long, looks like it rolled in sand. That protects it from predators. I saw maybe 25-30 of these at low tide. Thanks to naturalist Ian Hutton for pointing them out to me.
