Table 1 in Description Of The Agonistic Behavior Of Aegla Longirostri (Decapoda: Aeglidae)

<p>Table 1. Behavioral acts by males of <i>Aegla longirostri</i>, codes and descriptions.</p><table><tbody><tr><th>Code</th><th>Behavior</th><th>Description</th></tr><tr><th>NON-AGGRESSIVE ACTS</th></tr><tr><th>Without displacement</th></tr></tbody><tbody><tr><th>WD1</th><td>Without activity</td><td>The animal stands still, without moving its appendages, with the body near the</td></tr><tr><th></th><td></td><td>substrate, chelipeds directed forwards (near the back) and fingers open, or</td></tr><tr><th></th><td></td><td>chelipeds folded toward the cephalothorax, antennae directed forward, held</td></tr><tr><th></th><td></td><td>horizontally parallel to the body axis (on chelipeds).</td></tr><tr><th>WD2</th><td>With activity</td><td>The animal moves the pereiopods constantly (leg waving) and/or chelipeds or</td></tr><tr><th></th><td></td><td>antennae, always still; and keeps the chelipeds folded near the body and the</td></tr><tr><th></th><td></td><td>maxillipeds in motion.</td></tr><tr><th>With displacement (without real aggression)</th></tr><tr><th>WK</th><td>Walking</td><td>The animal walks slowly in the arena, with the body near the substrate, antennae</td></tr><tr><th></th><td></td><td>directed forward, parallel to the body axis, chelipeds directed down, folded, not</td></tr><tr><th></th><td></td><td>directed forward, or else chelipeds towards the front and open. Sometimes the</td></tr><tr><th></th><td></td><td>animal brings the cheliped to the maxillipeds, and moves the appendices</td></tr><tr><th></th><td></td><td>(antennae). This action is a way of exploring the arena.</td></tr><tr><th>CA</th><td>Climbing arena</td><td>The animal makes an attempt with chelipeds, pereiopods, and abdomen to climb the</td></tr><tr><th></th><td></td><td>arena walls. Antennae and chelipeds directed forward, chelipeds open, tailflips,</td></tr><tr><th></th><td></td><td>and movement of pereiopods.</td></tr><tr><th>AGGRESSIVE ACTS</th></tr><tr><th>AP</th><td>Approaching</td><td>An animal walks slowly toward the opponent; sometimes the antennae are directed</td></tr><tr><th></th><td></td><td>forwards and are in motion.</td></tr><tr><th>WA</th><td>Walking away</td><td>The animal slowly moves aside from the opponent, with abdomen directed toward the</td></tr><tr><th></th><td></td><td>opponent, generally it goes to one of the corners of the arena. The animal walks</td></tr><tr><th></th><td></td><td>away while the other animal approaches, but this does not characterize escaping,</td></tr><tr><th></th><td></td><td>because there is no signal of contact, only the approach of one animal leads the</td></tr><tr><th></th><td></td><td>other to walk away.</td></tr><tr><th>FF</th><td>Face to face</td><td>The animals remain still, face to face, one body length apart, antennae directed to the</td></tr><tr><th></th><td></td><td>front, chelipeds also directed to the front and very stretched, but sometimes the</td></tr><tr><th></th><td></td><td>chelipeds move toward the maxilliped.</td></tr><tr><th>To attack/the attack: when an animal chases its opponent and there is physical contact. The animals show the following behavioral postures during the</th></tr><tr><th>performance of the acts: chelipeds directed to the front, open and slightly raised; or chelipeds open and held high, antennae held perpendicular to the</th></tr><tr><th>animal&rsquo;s body.</th><td></td></tr><tr><th>HQ</th><td>Hitting with chelipeds</td><td>An animal hits or &lsquo;&lsquo;passes&rsquo;&rsquo; with chelipeds on the opponent&rsquo;s carapace or chelipeds.</td></tr><tr><th>TO</th><td>Being touched with chelipeds</td><td>When an animal is touched with the opponent&rsquo;s chelipeds.</td></tr><tr><th>PQ</th><td>Pulling/pinching with chelipeds</td><td>Consists of pressing and pulling quickly the cheliped (or the pereiopods) of the</td></tr><tr><th></th><td></td><td>opponent. The animal tries to catch the opponent, but it cannot, during this act the</td></tr><tr><th></th><td></td><td>antennae (generally) remain horizontal to the body.</td></tr><tr><th>PO</th><td>Being pulled with chelipeds</td><td>When the animal is pulled by the opponent&rsquo;s chelipeds, which may pull on both the</td></tr><tr><th></th><td></td><td>chelipeds and pereiopods.</td></tr><tr><th>CQ</th><td>Holding (catching) with chelipeds</td><td>Consists of holding (catching) the opponent with chelipeds. Generally the part which</td></tr><tr><th></th><td></td><td>is held is the chelipeds of the other animal or even the pereiopods and antennae,</td></tr><tr><th></th><td></td><td>and sometimes the animals try to catch the opponent&rsquo;s cephalothorax.</td></tr><tr><th>CO</th><td>Being held (caught) with chelipeds</td><td>When the animal is held by the opponent&rsquo;s chelipeds, which may hold chelipeds,</td></tr><tr><th></th><td></td><td>pereiopods, antennae, and even the cephalothorax of the other animal.</td></tr><tr><th>WhA</th><td>Whipping with antennae</td><td>This is a quick below with the antennae toward the back of the body, and the</td></tr><tr><th></th><td></td><td>opponent is behind the performer of the act.</td></tr><tr><th>TA</th><td>Touch with antennae</td><td>Consists in touching the opponent quickly with the antennae; the opponent being near</td></tr><tr><th></th><td></td><td>the front of the animal, the touch occurs both on the body and the antennae of the</td></tr><tr><th></th><td></td><td>opponent (commonly observed during combat).</td></tr><tr><th>DB</th><td>Pushing the opponent/displacing the body</td><td>One animal tries to displace the other pushing it with its own body (abdomen or</td></tr><tr><th></th><td></td><td>cheliped).</td></tr><tr><th>DO</th><td>Being pushed/ displaced by the opponent&rsquo;s body</td><td>When the animal is moved by being pushed by the opponent; the pushing is</td></tr><tr><th></th><td></td><td>performed with the chelipeds or even the abdomen.</td></tr><tr><th>TOD</th><td>Turning the opponent upside down</td><td>During the combat an animal turns the opponent over, leaving it with the ventral part</td></tr><tr><th></th><td></td><td>of the body up.</td></tr><tr><th>BTO</th><td>Being turned by the opponent</td><td>When an animal is turned over by its opponent and remains with the ventral part of</td></tr><tr><th></th><td></td><td>the body up.</td></tr><tr><th>GO</th><td>Going up the opponent</td><td>An animal goes totally up over the opponent&rsquo;s body, even when one of them is</td></tr><tr><th></th><td></td><td>climbing the arena.</td></tr><tr><th>BCO</th><td>Being &lsquo;&lsquo;climbed&rsquo;&rsquo; by the opponent</td><td>When an animal is &lsquo;&lsquo;climbed&rsquo;&rsquo; by the opponent.</td></tr><tr><th>Ch</th><td>Chasing</td><td>An animal chases (quickly approaching) the opponent, while the latter attempts to</td></tr><tr><th></th><td></td><td>escape.</td></tr><tr><th>Fl</th><td>Fleeing</td><td>The animal attempts to flee, walking or climbing the arena. The opponent approaches</td></tr><tr><th></th><td></td><td>and the animal escaping moves rapidly in another direction. In this act, the animal</td></tr><tr><th></th><td></td><td>keeps the antennae towards the front. One animal chases the other, which escapes,</td></tr><tr><th></th><td></td><td>sometimes with subtle contacts (with chelipeds and/or antennae).</td></tr></tbody></table>
