Crown-of-thorns starfish larvae feast on toxic cyanobacteria, study finds

Researchers have uncovered an under-the-sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as "sea sawdust."

[da capo] Of Terms in Biology: Neuston

<p>by Merry  <br /> When I stumbled across the term bacterioneuston, I discovered a whole new world where the air meets the sea. I found that marine neuston had long been used to refer to the diverse flora and fauna inhabiting the topmost 5 cm of the oceans — a distinctly different assemblage than found in the waters below.

How an ocean-fertilising bacterium forms aggregates

Movement of filaments of Trichodesmium and their interactions with other filaments help form aggregates

A team of environmental engineers at ETH Zurich's Institute of Environmental Engineering working with a colleague from the University of Luxembourg has found that the movement of individual gliding filaments of Trichodesmium and the way they interact with other filaments helps them to form aggregates. In their study, published in the journal Science, the group studied how samples of Trichodesmium in their lab reacted to environmental events such as bright light.
