Evidence for male allocation in pipefish?
Nature, 2010Sexual 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

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, 1995AbstractIn 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.

Selective males and ardent females in pipefishes
Behavioral Ecology and Sociobiology, 1993In the pipefishes Syngnathus typhle and Nerophis ophidion, males have been shown to limit female reproductive rate, and females to compete for access to males. Hence, these species fit the criteria for sex-role reversal. Males brood the eggs and provide the offspring with nutrients, oxygen and an osmoregulated environment. Moreover, in S.
