But nearby algae lacked telltale feeding holes.<\/p>\n\n\n\n<p>Time-lapse photography confirmed the amoebas were vampyrellids. But they didn\u2019t feed like other microscopic vampires. The unicellular blobs engulfed and split apart <em>Closterium<\/em> algae cells, sucking out the insides and tossing the rest.<\/p>\n\n\n\n<p>\u201cWe just couldn\u2019t believe it at first,\u201d Suthaus says. \u201cOf course, the question becomes, well, how exactly do [the amoebas] do it?\u201d<\/p>\n\n\n\n<p>Feeding experiments revealed that <em>S. ruptor<\/em> keeps engulfed algae in a special compartment. Enzymes in this chamber appear to dissolve one side of the prey\u2019s cell wall. The other side is attached to the chamber wall. As the compartment expands, the algae cell swings open like a shelled pistachio.\u00a0<em>S. ruptor<\/em> then reaches into itself to scoop up its meal, bundling up and spitting out the empty cell wall.\u00a0<\/p>\n\n\n\n<p>The odd vampyrellids belong to a previously undescribed genus and species, a genetic analysis suggests. The genus name <em>Strigomyxa, <\/em>which derives from the ancient Greek words for <em>owl<\/em> and <em>mucus<\/em> or <em>slime<\/em>, is a nod to the microbe\u2019s owllike regurgitation behavior.<\/p>\n\n\n\n<p>\u201cWhen you see similar pellet-casting in a lot of other organisms, they have multiple cells that fulfill multiple functions. And this is a single cell doing this type of mechanistic action,\u201d Suthaus says. \u201cIt tells us about the ingenuity of evolution.\u201d<\/p>\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/amoeba-eats-removes-shell\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>Extreme Climate Survey Science News is collecting reader questions about how to navigate our planet&#8217;s changing climate.
