“…In each case, the most common haplotype was shared across the majority of in situ origins, and the other haplotypes were also evenly spread around the country, yet often only represented by a single individual. The cytochrome b haplotype sequences provided by Wilson et al (2001) and Casey et al (2004) were removed by 4Á14 mutational steps, which also translates as a sequence divergence in the range of 0.5Á1.7%, with those originating from Australia placed furthest away.…”

“…Maximum likelihood and Bayesian phylogenetic trees were generated within Geneious with the use of the PhyML (Guindon & Gascuel 2003) and MrBayes (Huelsenbeck & Ronquist 2001) plugins to show the relationship of the new cytochrome b sequences in reference to other published Hippocampus genbank sequences by Casey et al 2004 (AF192642ÁAF192706; less six identical sequences in the set), Wilson et al 2001 (AF356049, AF356054, AF356057, AF356063, AF356065 and AF356071) and Kawahara et al 2008 (AP005985). Two sequences from different genera, Sygnathus typhle (AF356042) and Microphis brachyurus (AF356046) by Wilson et al (2001) were included as outgroups to root the trees.…”

“…Furthermore, the nucleotide and haplotype diversities seen here fall within the ranges described for other seahorse species, such as the H. kuda complex (Teske et al 2005), H. capensis (Teske et al 2003) and H. trimaculatus . Casey et al (2004) carried out the largest comparison within the Hippocampus genus, and observed putative intra-specific distances of 1.1Á5.9%, and distances of 1.3Á23.2% between species.…”

Genetic diversity and population structure of New Zealand populations of the pot-belly seahorse Hippocampus abdominalis were explored via three mitochondrial DNA markers (814 bp of cytochrome b, 624 bp of cytochrome oxidase 1 and 404 bp of the control region) and four microsatellite loci (Habd3, Habd6, Habd7 and Habd9). These markers revealed between 0.7Á2.2% sequence divergence and 32Á46 alleles with low differentiation among populations around the coastline. In total, 169 seahorses (79 females and 90 males) were sampled with 36 sequences generated for each marker and 166 genotypes attained. It is hoped that this new knowledge will aid in the development of future conservation management.

The family Syngnathidae diverged from other teleosts approximately 48 Mya; they originated from Indo‐Pacific regions and then diversified and spread globally. Subsequently, a unique animal group, fishes with ‘male pregnancy’, emerged. Together with their morphological traits, syngnathid fishes established a specialised evolutionary position. Interestingly, all 300 species in this family lost their pelvic fin, which is directly correlated to the absence of the tbxt4 gene. In this family, pregnancy relies on the attached brood pouch in males, and the structure of the pouch varies dramatically within the family owing to their independent evolutionary history. Some species, such as seahorses, have a fully enclosed brood pouch with robust functions. The phylogenomics and adaptive evolution of the species in the family Syngnathidae might elucidate further mechanisms involved in their morphology and male pregnancy. Key Concepts Phylogeny and evolutionary morphology in the family Syngnathidae. Syngnathidfishes represent the endless beauty of the evolution of marine organisms. Syngnathids origin from the Indian‐Pacific and spread globally. Comparative genomics elucidate the genetic basis of the specialized morphology of syngnathids. ‘Male pregnancy’ could be implemented in syngnathids by evolving a complex brood structure and the evolution of genes.
