Sea snake approaches to divers
<p>Scuba-divers on tropical coral-reefs often report unprovoked "attacks" by highly venomous Olive sea snakes (<i>Aipysurus laevis</i>). Snakes swim directly towards divers, sometimes wrapping coils around the diver's limbs and biting. Based on a focal animal observation study of free-ranging Olive sea snakes in the southern Great Barrier Reef, we suggest that these "attacks" are misdirected courtship responses. Approaches to divers were most common during the breeding season (winter) and were by males rather than by female snakes. Males also made repeated approaches, spent more time with the diver, and exhibited behaviours (such as coiling around a limb) also seen during courtship. Agitated rapid approaches by males, easily interpreted as "attacks", often occurred after a courting male lost contact with a female he was pursuing, after interactions between rival males, or when a diver tried to flee from a male. These patterns suggest that "attacks" by sea snakes on humans result from mistaken identity during sexual interactions. Rapid approaches by females occurred when they were being chased by males. Divers that flee from snakes may inadvertently mimic the responses of female snakes to courtship, encouraging males to give chase. To prevent escalation of encounters, divers should keep still and avoid retaliation.</p>

FIGURE 3. Correlogram showing the Spearman correlations among the coral (top 2 lines, left 2 columns) and brittle star (bottom 9 lines, right 9 columns) variables. Lower panel: blue gradient indicating a positive correlation (dark blue meaning high correlation) and red gradient indicating a negative correlation (dark red meaning a strong negative correlation). Diagonal: probability density functions for individual variables. Upper panel: biplots corresponding to each variable pair. Sample sizes: n=10 for lines 1–2, n=52 for lines 3–5 (with data on oral and aboral sides of the ophiuroids, see methods), n=124 for lines 6–10 (with data on aboral side only, see methods).
