Breeding Female of the Pipefish

Nature, 1950
THE following notes on the breeding female of the pipefish Nerophis lumbriciformis (Pennant) may be of interest to zoologists. One in breeding dress was taken in the Laminaria zone early in April 1946, at Mahee Island, Co. Down, Northern Ireland. It was in the company of several other females of normal appearance.

Male pipefish prefer ornamented females

Animal Behaviour, 2001
In the sex-role reversed pipefish Syngnathus typhle females compete for access to males and males are choosy. Females display a temporary ornament, a striped pattern. We show here for the first time in a sex role-reversed species that ornament display predicts how much time a female will devote to competitive behaviours, that males prefer ornamented ...

Ovary of the pipefish, Syngnathus scovelli

Journal of Morphology, 1987
AbstractGross dissection, light microscopy, and transmission electron microscopy were used to generate a detailed understanding of the ovarian anatomy of the pipefish, Syngnathus scovelli. The ovary is a cylindrical tube bounded by an outer layer consisting of a smooth muscle wall and an inner layer of luminal epithelium, with follicles sandwiched ...

Sex Role Reversal in Pipefish

2003
Publisher Summary The chapter presents the problem in two sex role-reversed pipefish species. The chapter discusses why potential reproductive rates differ and the consequences of this “reversed” mating competition on sexually selected traits in females.

Mitochondrial DNA variability of the pipefish Syngnathus abaster

Journal of Fish Biology, 2013
This study provides data on the genetic structuring of the pipefish Syngnathus abaster in the western Mediterranean and Adriatic Seas. A total of 109 specimens were collected in brackish‐water biotopes. The control region and three other regions of the mitochondrial genome were analysed.

Evidence for male allocation in pipefish?

Nature, 2010
Sexual differences in the extent and type of parental care lie at the heart of sexual selection theory, and evolution resulting from parental conflict has produced some striking behavioural and morphological adaptations. In a study of male pregnancy in Gulf pipefish, Paczolt and Jones showed that more eggs were transferred to the male's brood pouch and

Straight‐nosed pipefish Nerophis ophidion and broad‐nosed pipefish Syngnathus typhle avoid eelgrass overgrown with filamentous algae

Journal of Fish Biology, 2011
In a habitat choice experiment straight‐nosed pipefish Nerophis ophidion and broad‐nosed pipefish Syngnathus typhle avoided eelgrass Zostera marina covered with filamentous algae. Both juveniles as well as brooding adult males of the two species clearly preferred to position themselves in Z. marina without growth of filamentous algae.

Many Mates Make Male Pipefish Choosy

Behaviour, 1995
AbstractIn the sex-role reversed pipefish Syngnathus typhle males search for mates, and prefer to mate with large rather than small females. When mate density was experimentally manipulated, males exerted a mate choice only under high mate density, whereas no mate choice could be demonstrated under low mate density.
