Straightnosed Pipefish Video Stock Footage
The straightnose pipefish initially gives the impression of being a worm. The head is tiny and resembles that of a seahorse, to which this fish is closely related. The body is round in cross-section and the fins are tiny. The only fish with which it might be confused is the broadnosed pipefish (Syngnathus typhle) but that is more robust and has a hexagonal cross-section. The general colour of the straightnose pipefish is green with a yellowish belly. The female has pale blue markings on the head and body and both sexes become more colourful at breeding time when the male’s snout turns yellow. The average size is about 15 to 20 cm (6 to 8 in) with a maximum of 30 cm (12 in). This species of pipefish is used as a model to study mate choice and sex role-reversal. Like other species of pipefish and the closely related seahorses, the straighnose pipefish exhibits male parental care, meaning that female reproductive success is limited by her ability to court and mate with a suitable male. In the straighnosed pipefish, female-female competition and mate choice by males has resulted in female-specific coloration, female ornamental skin folds, and more active courtship in females.
