Biodiversity of cone snails and other venomous marine gastropods: evolutionary success through neuropharmacology.
TLDR
Molecular phylogeny and venom peptide characterization provide an unusual multidisciplinary view of conoidean biodiversity at several taxonomic levels and the associated morphological, behavioral, and prey-preference changes that accompany these molecular changes are unknown.

Divergence of the Venom Exogene Repertoire in Two Sister Species of Turriconus
TLDR
Comparative analysis with closely related species and more distantly related species suggests that speciation is associated with significant diversification of individual toxin genes (exogenes) whereas the expression pattern of toxin gene superfamilies within lineages remains largely conserved.

Phylogenetic inference and peristome evolution in haplolepideous mosses, focusing on Pseudoditrichaceae and Ditrichaceae s. l .
TLDR
The molecular analysis resolves Pseudoditrichum in a clade with Chrysoblastella chilensis (formerly Ditrichaceae) in the haplolepideous lineage and confirms the polyphyly of DItrichaceae is confirmed by molecular phylogenetic analysis.

Phylogeny and systematics of mitriform gastropods (Mollusca: Gastropoda: Neogastropoda)
TLDR
The present study aimed at the reconstruction of phylogenetic relationships of mitriform gastropods based on representative taxon sampling, and recovered Mitridae as a monophyletic group, whereas the genus Mitra was found to be polyphyletic.

Toxoglossan gastropods of the subfamily Crassispirinae (Turridae) lacking a radula, and a discussion of the status of the subfamily Zemaciinae
TLDR
It is concluded that similar foregut arrangement appeared independently in both lineages, and doubts are expressed concerning the importance of these characters in establishing a new taxon of subfamilial rank and therefore the validity of the subfamily Zemaciinae.

Phylogeny and taxonomy of the Kermia–Pseudodaphnella (Mollusca: Gastropoda: Raphitomidae) genus complex: a remarkable radiation via diversification of larval development
TLDR
A switch from planctotrophic to non-planctOTrophic mode of development occurred at least four times in the evolutionary history of the Kermia–Pseudodaphnella complex, indicating high developmental plasticity of the group.

Morphology and development of the valve of Leiblein: Possible evidence for paraphyly of the Neogastropoda
Neogastropoda are generally considered to be monophyletic, although their monophyly is usually challenged in molecular phylogenies. Such results suggest that serious reconsideration of the…
Venom Insulins of Cone Snails Diversify Rapidly and Track Prey Taxa
TLDR
It is shown that many worm-hunting and snail-hunter cones also express venom insulins, and that this novel gene family has diversified explosively.
