“…Despite being found on opposite sides of the Atlantic and in caves of significantly different age and geology, the polynoid anchialine cave genera Pelagomacellicephala and Gesiella were found as sister taxa and shared several similar traits that can be interpreted as troglomorphic adaptations (Wilkens et al., ; Gonzalez et al., ) (see Fig. ).…”

Aphroditiformia represents one of the most successful radiations of annelids, and is therefore an interesting model to understand morphological and functional evolution. Previous phylogenetic analyses yielded most families as monophyletic but excluded anchialine and interstitial species while failing to recover relationships within Sigalionidae. Here we address these shortcomings through the analysis of four molecular markers and 87 morphological characters sampled across 127 species under the assumptions of parsimony and model-based methods. Of the 34 newly sequenced taxa, five anchialine and 24 interstitial species were included, with increased representation of Sigalionidae. An additional 28 elusive Sigalionidae taxa were included, represented only by morphological partitions. Molecular and morphological partitions were evaluated under exhaustive sensitivity analyses, testing the effects of alignment algorithms and optimization criteria on tree topologies. Our trees congruently recovered six clades corresponding to the families within Aphroditiformia: Acoetidae, Aphroditidae, Eulepethidae, Iphionidae, Polynoidae and Sigalionidae, respectively. An anchialine polynoid lineage was nested among strictly deep sea species, and interstitial pisionids and pholoids formed two independent clades nested within Sigalionidae. Additionally, Sigalionidae resulted in four clades, defined by combinations of apomorphies, and hereby we propose the subfamilies Pelogeniinae, Pholoinae, Pisioninae, Sthenelanellinae, as well as the provisionally included polyphyletic Sigalioninae.

“…Among cave annelids, suspension feeding has been described in several groups, facilitating their access to trophic resources that are more abundant in the water column and density interfaces (Martínez et al., ; Worsaae et al., ). Within scale worms, swimming behaviour has been recorded in the polynoids Gesiella and Pelagomacellicephala (Gonzalez et al., ; Wilkens et al., ) , as well as in the holopelagic genera Drieschia and Podarmus (Jumars, Dorgan, & Lindsay, ). Unfortunately, no DNA sequences for these latter two genera were available for inclusion in our analyses, and we therefore cannot analyse their potential adaptations.…”

Anophthalmia and elongation of body appendages in cave scale worms (Annelida: Aphroditiformia)

This study addresses whether cave dwelling annelids exhibited similar reductive and constructive traits equally as strong as those of arthropods and vertebrates inhabiting caves. Known as troglomorphism, these adaptations bring about striking morphologies across invertebrates and vertebrates from both aquatic and terrestrial cave habitats, and include varying degrees of eye and pigmentation loss, as well as hypertrophy of body appendages and sensorial structures. Employing phylogenetic comparative methods and ancestral character reconstructions on a worldwide data set of a group of annelids, the scale worms (Aphroditiformia), we investigate the behavioural and morphological traits of species living in marine caves in comparison with those species living outside caves. Our work demonstrated that cave scale worms respond similar to arthropods in cave environments, showing a significant elongation of sensory parapodial cirri, while lacking eyes and pigmentation. However, whereas elongation of sensory appendages likely occurred in correlation to cave colonization, eyes were plausibly lost in correlation with specialization and colonization of deepsea habitats.

“…Fully marine caves and anchialine lave tubes (e.g., Corona lava tube; Lanzarote, Canary Islands) receive direct and repeated tidally forced inputs of organic matter from the coastal ocean (Fichez, 1991a, b;Wilkens et al, 2009). In contrast, inland anchialine caves additionally receive terrestrial organic matter inputs from sources that may be located hundreds to thousands of meters from the coast (van Hengstum et al, 2010), and an in situ chemoautotrophic organic matter source is hypothesized for the Systema Naranjal anchialine cave network in the Yucatan Peninsula, Mexico (Pohlman, 1995;Pohlman et al, 1997).…”

Recent investigations of anchialine caves and sinkholes have identified complex food webs dependent on detrital and, in some cases, chemosynthetically produced organic matter. Chemosynthetic microbes in anchialine systems obtain energy from reduced compounds produced during organic matter degradation (e.g., sulfide, ammonium, and methane), similar to what occurs in deep ocean cold seeps and mud volcanoes, but distinct from dominant processes operating at hydrothermal vents and sulfurous mineral caves where the primary energy source is mantle derived. This review includes case studies from both anchialine and non-anchialine habitats, where evidence for in situ chemosynthetic production of organic matter and its subsequent transfer to higher trophic level metazoans is documented. The energy sources and pathways identified are synthesized to develop conceptual models for elemental cycles and energy cascades that occur within oligotrophic and eutrophic anchialine caves. Strategies and techniques for testing the hypothesis of chemosynthesis as an active process in anchialine caves are also suggested.
