Old joke: How do lionfish mate?

Lionfish interrupted

Very carefully.

The logistics seem difficult with all those spines… but I might have disturbed a tender moment between two poisonous, beautiful fish.

A reef destroying invasive species…

Nightmare starfish

…that isn’t man. Let me introduce you to a Crown of Thorns, A voracious and difficult to destroy starfish, owing to its spiny carapace and neurotoxin defense. Rumors also abound that slicing it up causes it to regenerate in Hydra fashion, but that’s not exactly true.

They are the subject of campaigns to control or eliminate them, as they’re destroying reefs in many parts of the world, as they eat live coral. Australia has been particularly hit, though I’ve seen plenty in the Andamans.

Theories as to why they’re spreading include human-caused reductions in their natural predators and algal blooms (caused by fertilizer runoff) providing alternative food sources to the fish that might otherwise eat starfish larva.

Tucked away, waiting for dark

Shy

What I presume is another type of feather star, hiding away until dark when it will unfold and feed.

Back to the ocean

Like a clenched fist

This is some sort of feather star, brought to us from Jackson’s Bar off near Havelock Island in the Andamans. I’ve been obsessing about diving lately as my next trip will be focused entirely on breathing compressed air and marine conservation research in a central American country this March.
