- Movie S1. Attack on Sea Hare
by Spiny Lobster Results in Behavior Suggestive of Phagomimicry and Sensory Disruption
A spiny lobster (Panulirus
interruptus) attacks a sea hare (Aplysia californica) and halts attack after the sea hare releases secretions. The spiny lobster
then shows behavior suggestive of phagomimicry (grabbing and digging) and sensory disruption (grooming of mouthparts and antennules).
(Note that the sea hare in this video is larger than the individuals used in our actual experiment.) The following chronology
of events can be observed: At 1 s, spiny lobster attacks sea hare, which releases ink and opaline; at 5 s, spiny lobster stops
attacking and moves to the area where the substrate is coated with secretions; at 6 s, grooming of mouthparts; at 13–14 s,
grooming of mouthparts; at 15–16 s, grabbing; at 17–19 sec, grooming of antennules; from 20 s until the end of video, digging.
- Movie S2. Attack on Sea Hare by Spiny Lobster Results in the Chemosensory Organs of Spiny Lobster Becoming
Coated with Sticky Secretions
This close-up view of the antennule, the olfactory organ of the spiny lobster,
shows that it becomes coated with secretion after the attack on a sea hare and the sea hare’s release of ink and opaline.
Such coating may lead to impairment of the normal function of this sensory organ (i.e., sensory disruption). The following
chronology of behaviors can be observed: At 5 s, spiny lobster attacks sea hare; at 16 s, sea hare releases opaline; at 21
s, sea hare releases ink; from 31 s untilthe end of video, antennules of spiny lobster are coated with opaline.
- Movie S3. Attack on Sea Hare by Spiny Lobster Results in Behavior Suggestive of Aversion and Sensory Disruption
A
spiny lobster attacks a sea hare, backs away after secretions are released (aversive behavior), and then repeatedly grooms
the mouthparts and antennules (sensory disruption). (Note that the sea hare in this video is larger than the individuals used
in our actual experiment.) The following chronology of behaviors can be observed: At 0 s, spiny lobster attacks sea hare;
at 6 s, sea hare releases ink and opaline; at 8 s, spiny lobster backs away from sea hare; at 11 s, spiny lobster attacks
sea hare again; at 13 s, spiny lobster moves away from sea hare again; at 20–22 s, grooming of mouthparts; at 23–32 s, grooming
of antennules; from 32 s until the end of video, grooming of mouthparts and antennules; at 36 s, spiny lobster backs into
sea hare and then moves away.
