A comparative analysis of the ontogeny of syngnathids (pipefishes and seahorses) reveals how heterochrony contributed to their diversification

Developmental Dynamics, Journal Year: 2022, Volume and Issue: 252(5), P. 553 - 588

Abstract Background Syngnathids are a highly derived and diverse fish clade comprising the pipefishes, pipe‐horses, seahorses. They characterized by plethora of iconic traits that increasingly capture attention biologists, including geneticists, ecologists, developmental biologists. The current understanding origins their body plan is, however, hampered incomplete limited descriptions early syngnathid ontogeny. Results We provide comprehensive description development Nerophis ophidion , Syngnathus typhle Hippocampus erectus from cleavage stages to release male brooding organ beyond, juvenile development. comparatively describe skeletogenesis with particular focus on dermal bony plates, snout‐like jaw morphology, appendages. Conclusions This most detailed account date suggests convergent phenotypes (e.g., reduction loss caudal fins), likely arose distinct ontogenetic means in pipefishes Comparison trajectories S. H. provides indications characteristic features seahorse result truncation. Altogether, this work valuable resource framework for future research understand evolution outlandish morphology perspective.

Genome rearrangements, male pregnancy and immunological tolerance – the curious case of the syngnathid immune system

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

The syngnathid fish group (seahorses, pipefishes and seadragons) is a fascinating lineage associated with an array of evolutionary peculiarities that include diverse morphologies their unique male pregnancy. These oddities also extend to immune systems, growing body research highlighting range intriguing immunological characteristics genomic rearrangements, which pose questions regarding history strategies. functional loss the major histocompatibility complex class II pathway (MHC II) in Syngnathus genus related components seahorse ( Hippocampus ) were two discoveries initially piqued interest. This sparked discussions concerning capabilities, possible facilitative roles advanced pregnancy evolution through means evoking tolerance, as well general re-evaluation how we interpret vertebrate plasticity. Experimental approaches have attempted clarify further impact repertoire on efficacy response, specificities pathways play during concept inheritance. first characterization cell typhle using scRNA-seq represents latest step understanding dynamics these enigmatic fish. report serves review for insights into group; encompassing history, populations, links pregnancy, sex specificity, addition future opportunities need investigation.
