Fig 1.
Maximum mean recorded tentacle lengths (mean length mm, n = 6) for Carukia barnesi over a range of medusae bell sizes (niche bell height mm).
Fig 2.
Carukia barnesi mean tentacle extension, as a percentage, over 360 minutes, exposed to light (○, dashed line) and dark (△, solid line) treatments.
Error bars represent 95% confidence intervals (n = 6).
Fig 3.
The number of tentacle twitches recorded for Carukia barnesi, over one minute intervals (twitch rate per minute), plotted against different tentacle extensions (percent extension).
Video footage was analyzed in approximately 30 minute intervals (i.e. 6 specimens measured 9 times each).
Fig 4.
The mean number of tentacle twitches recorded for Carukia barnesi, over one minute intervals (twitch rate per minute) plotted against medusae bell size in millimeters.
Error bars represent 95% confidence intervals (n = 6).
Fig 5.
Envenomation of a larval fish (Acanthochromis sp.) that was captured by a twitching tentacle of an adult Carukia barnesi.
a: envenomation site; b: nematocyst cluster; c: bell. The bell size of this specimen is approximately 15 mm in height and the fish is approximately 10 mm in length.
