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