“…Within this group, significant changes occur at the base of a clade including Catherinum and more derived taxa (node 9, nine changes, 97% bootstrap support), and at the base of Weltnerium (node 11, 11 changes, 99% bootstrap support). Weltnerium includes the morphologically most derived scalpellids, which also show highly specialized reproductive strategies (Buhl‐Mortensen & Høeg, , ).…”

“…Much recent interest in scalpellids has focused on their reproductive strategies (Buhl‐Mortensen & Høeg, , ; Yusa et al ., ). Plesiomorphically, scalpellids are thought to be hermaphroditic (Foster, ), and the most basal living scalpellids identified here are hermaphrodites ( Diotascalpellum diota (Hoek) and D. rubrum ).…”

“…Plesiomorphically, scalpellids are thought to be hermaphroditic (Foster, ), and the most basal living scalpellids identified here are hermaphrodites ( Diotascalpellum diota (Hoek) and D. rubrum ). More derived scalpellids (many Amigdaloscalpellinae) are androdioecious, the hermaphrodites housing dwarf males inside the scuta above the adductor muscle (Darwin, ; Yusa et al ., ), and others are dioecious, with large females and dwarf males (Buhl‐Mortensen & Høeg, , ; Yusa et al ., ). The interior of the scutum (Figs , ) thus provides evidence of the level of reproductive specialization that can be applied to the fossil record (Høeg et al ., unpubl.…”

“…This is a very small species: the scuta have a maximum height of 2 mm, and the total height of the individuals was probably not more than 5 mm. It was possibly attached to living crustaceans or pycnogonids, by analogy with the small extant species Weltnerium nymphocola (Hoek, ) and Verum brachiumcancri Weltner (see Buhl‐Mortensen & Høeg, ).…”

“…The present study of scalpellid plate morphology was initially stimulated by Jens Høeg, whose detailed work on scalpellid reproductive systems (Buhl‐Mortensen & Høeg, , ; Yusa et al ., ) posed important questions concerning the phylogenetic relationships of species. Recently, Lin et al .…”

A cladistic analysis of 23 extant species of the deep‐sea pedunculate cirripede family Scalpellidae was undertaken, based on 61 shell plate characters, and taking the Jurassic–Cretaceous scalpellomorph genus Cretiscalpellum as an out‐group. The consensus tree shows progressive morphological change from basal to more derived taxa, but a derived group is marked by major morphological innovation, including 27 character state changes that permit subdivision of the family into two sharply demarcated clades – the more basal group is here placed within a redefined Scalpellinae (Arcoscalpellum, Arcuatoscalpellum gen. nov., Diotascalpellum gen. nov., Graviscalpellum, Regioscalpellum gen. nov., and Scalpellum), and a more derived group named Amigdoscalpellinae subfam. nov. that shows numerous progressive trends in morphology, permitting the recognition of three genera (Amigdoscalpellum, Catherinum, and Weltnerium). The phylogeny is independently supported by a recently published multiple DNA marker‐based molecular phylogeny. The more basal Scalpellinae appeared in the Aptian (Early Cretaceous, 120 Mya), and derived Amigdoscalpellinae were already present by the Campanian (Late Cretaceous, 78 Mya), represented by Catherinum anglicum sp. nov. and Amigdoscalpellum bellulum from the UK Chalk. Specialized receptacles to accommodate dwarf males in the apical interior of the scutum evolved at least three times during the history of the scalpellids. © 2015 The Linnean Society of London

Crustaceans are a morphologically, physiologically, and ecologically highly diverse animal group and correspondingly diverse are their reproductive characteristics. They have evolved structural specialties with respect to penis construction, sperm form, sperm storage, fertilization, and brood care. Unique in the animal kingdom are safety lines that safeguard hatching and first molting. Further curiosities are dwarf males in parasitic and sessile crustaceans and bacteria-induced feminization and gigantism of crustacean hosts. Record-breaking features are relative penis length, sperm size, clutch size, chromosome number, viability of dormant eggs, and fossil ages of penis, sperm, and brooded embryos. These examples from a single invertebrate subphylum and a single life history aspect illustrate that morphological solutions to functional requirements can be as spectacular as behavioral adaptations. They may provide valuable sources for comparative morphologists, ecologists, evolutionary biologists, and applied biologists to advance topical issues such as sperm competition, posthumous paternity, evolution of brood care, adaptation to freshwater, infectious feminization, sustainable male-based fishery, maintenance of genetic diversity under conditions of limited mating opportunity, and long-term impact of pollution on genotype and phenotype.
