Figure 1

Live observations of Histiobalantium bodamicum (A–C), Vorticella natans (G–J), and the prey Cryptomonas sp. strain 26.80 (D–F). Arrows in (A) and (H–J) show the ingested Cryptomonas sp. strain 26.80; the arrow in (G) marks the helical contracting stalk; (B) and (C) are FlowCAM images captured at 18 and 18.5 °C, respectively. Note that when temperature increased above 18 °C, H. bodamicum turned from a fit feeding state (B) to a starved state (C). Scale bar = 30 µm in (A); = 20 µm in (B, C); = 4 µm in (D–E); 25 µm in (G, H, J); = 10 µm in (I).
