Social monogamy in the fiddler crab Uca capricornis: The response of paired crabs when faced with intruders of differing sex
Australian Ocean Data Network (AODN)A unique relationship exists between neighbouring males and females in the fiddler crab Uca capricornis. This experiment was designed to determine if males and females are unable to associate with multiple partners because their partners aggressively repel…

Quantifying colour patterns on the black carapace of the fiddler crab Uca capricornis
Australian Ocean Data Network (AODN)Fiddler crabs are often spectacularly coloured and capable of dramatic colour changes. While the adaptive significance of variation resulting from short- or long-term colour changes is generally well known, the phenotypic diversity in colour pattern between…

Colour changes associated with moulting in the fiddler crab, Uca capricornis
Australian Ocean Data Network (AODN)The purpose of the experiment was to quantitatively examine the colour changes associated with moulting in the fiddler crab, Uca capricornis. Experiments were conducted in the East Point Reserve, Darwin between Nov - Jan (04/05 & 05/06). Circular cages were…

Parent Record: Social monogamy in the fiddler crab Uca capricornis
Australian Ocean Data Network (AODN)Fiddler crabs are not generally considered subjects for the study of monogamy as they tend to live in dense mixed sex colonies with numerous neighbours and individually defended territories. Here, a series of experiments have been conducted demonstrating the…

Sex ratio and distribution within a large population of the fiddler crab Uca capricornis
Australian Ocean Data Network (AODN)The purpose of this experiment was to determine whether females may be a limited resource within a population of Uca capricornis. The experiment was part of a larger study looking at the relationship between neighbouring males and females in this species.…

The fiddler crab Uca mjoebergi uses colour vision in mate choice
Australian Ocean Data Network (AODN)The walking legs, carapaces and chelae of ocypodid crabs, particularly the well-studied fiddler crabs, are often brilliantly coloured. However, despite this array of colours there is still some debate over whether ocypodid crabs are actually capable of colour…

Daily colour changes associated with the fiddler crab, Uca capricornis
Australian Ocean Data Network (AODN)The purpose of this experiment was to examine the daily colour changes in relation to the tidal cycle in the fiddler crab, Uca capricornis. Experiments were conducted in the East Point Reserve, Darwin from Nov - Jan (04/05 & 05/06). Twenty-seven crabs (13…

Colour changes associated with the semilunar cycle in the fiddler crab, Uca capricornis
Australian Ocean Data Network (AODN)The purpose of the experiment was to examine the colour changes associated with the semilunar cycle in the fiddler crab, Uca capricornis. Experiments were conducted in the East Point Reserve, Darwin from Nov - Jan (04/05 & 05/06). 1m diameter cages were…

Natural male-female interactions and territoriality in the fiddler crab Uca capricornis
Australian Ocean Data Network (AODN)The behaviour of U. capricornis is not well-known. Consequently, observations were made for approximately 1100 hours over 4 seasons to obtain a general picture of their social system and behaviour. The study was conducted on a large population of Uca…

Burrow tenure in the fiddler crab Uca capricornis
Australian Ocean Data Network (AODN)Crabs sometimes vacate their territories due to continued harassment by their neighbours. To determine whether male-female pairs were longer lasting than male-male pairs, we documented the number of crabs that were still present in their same burrow after 24…

Rapid colour changes associated with the fiddler crab, Uca capricornis
Australian Ocean Data Network (AODN)The purpose of this experiment was to quantitatively examine the rapid colour changes associated with the fiddler crab, Uca capricornis. Experiments were conducted in the East Point Reserve, Darwin from Nov - Jan (04/05 and 05/06). 65 randomly selected crabs…

Neighbour-stranger relations in the fiddler crab Uca capricornis
Australian Ocean Data Network (AODN)A unique relationship exists between neighbouring males and females in the fiddler crab Uca capricornis. This experiment was designed to demonstrate how a male fiddler crab responds to different individuals tethered near to his burrow. The response of a male…

Size-assortative pairing in the fiddler crab Uca capricornis
Australian Ocean Data Network (AODN)A unique relationship exists between neighbouring males and females in the fiddler crab Uca capricornis. This experiment was designed to examine whether the nearest female or male neighbour was correlated with the size of a focal male. Throughout different…
