Peeking into the #Ocean’s Microscopic Baby Boom
hakaimagazine.com/videos-visua

"The rapid increase of #phytoplankton marks the biological spring in the ocean—#zooplankton proliferate with the sudden flush of food... While many #animals spend only a brief time in the soup before they settle to the #seafloor or become more mobile, some species live out the rest of their lives as #plankton... It’s astonishing how alien the larval forms of common #SeaCreatures can seem"

Weekend #Plankton #Factoid 🦐🦠
A new paper on #mixotrophs. These protists are both plants or animals. Some algae, often #dinoflagellates, can consume other organisms in addition to being able to photosynthesize. They switch as needed, and during the recent heat-waves driven by #ClimateChange, they become dominant. The fate of this production isn't well known because some species are often not preferred for grazing #zooplankton because of toxicity or armoured cell walls.
