Introduction
My research focuses on the systematics and morphology of brittle stars (Echinodermata). I work with SEM to study the microstructure of the brittle star skeleton to understand their evolution and their ontogeny. I also work with fossils.

The ophiuroid genus Ophioplinthaca is well characterized by the deep incisions in the disc. Prior to this study, it contained 32 accepted species, but species limits and geographic distributions were not well understood. The manned submersible vehicle ‘Shenhaiyongshi’ was used to collect ophiuroid specimens from the deep-sea seamounts and cold seep...

Article
Ophiuroidea are one of the most diverse classes among extant echinoderms, characterized by their flexible arms composed of a series of ossicles called vertebrae, articulating with each other proximally and distally. Their arms show a wide range of motion, important for feeding and locomotion, associated with their epizoic and non-epizoic lifestyles...
Article
Brittle stars are one of the most diverse classes of echinoderms distributed worldwide in marine habitats. In this study, brittle stars were sampled by hand from the intertidal zone of the Persian Gulf's western part to the Oman Sea, from locations accessible without the need of a boat or diving equipment. Sampling time was set in the first days of...

Ophiuroidea is the largest class among extant echinoderms, with over 2000 described species assigned to 33 families. Here, the first identification key to the recently revised classification was developed, and revised morphological descriptions were derived from it, expanding the previous short diagnoses. The key was built by analyzing internal and...
Article
The brittle star samples collected by the Danish cruise ‘Galathea II’ (1950–52) had not been studied completely. We examined the remaining deep-sea samples (>400 m) and present the species inventory, discussing taxonomic issues in relation to recent phylogenetic data. About 235 samples were examined, over 9,300 individuals, from 67 species and 74 s...

The first articulated remains of ophiuroids for the Mesozoic of South America are described from the Lower Cretaceous of Neuquén Basin, Argentina. The taxonomic analysis allows the assignment of the material described herein to the extinct genus Ophiopetra. The specimens belong to a new species, but considering the poor preservation, a new name is...

Accurate species delimitation is essential to properly assess biodiversity, but also for management and conservation purposes. Yet, it is not always trivial to accurately define species boundaries in closely related species due to incomplete lineage sorting. Additional difficulties may be caused by hybridization, now evidenced as a frequent phenome...
Article
During a faunistic survey on two shipwrecks in the northern Persian Gulf, several species of ophiuroid were collected in 2015 and 2016. Ophiactis modesta is reported for the first time in the Persian Gulf and Ophiothela venusta is re-described, because it has likely been misidentified in the past, possibly confused with Ophiopsammium semperi. Both...

Euryalids, which include the spectacular basket stars, form a morphologically aberrant group of brittle stars. Surprisingly, the most recent molecular work found them to be sister to ophiurid brittle stars, thus challenging the traditional dichotomy between euryalids and non-euryalids, and leaving an enormous ghost lineage of more than 100 million...

Recent advances in the morphological study of the brittle star skeleton have resulted in a new phylogeny, including both fossil and recent species. The character analysis relies on observation of specimens and SEM images, requiring lengthy and complicated verbal descriptions of structures. The drawbacks of this method are that words fail to accurat...

The phylogeny of the brittle stars has been problematic for centuries. Both morphological and molecular attempts failed to convincingly reconstruct the evolution of the class. We present a novel approach to reconstruct the ophiuroid phylogeny using new morphological characters found by direct observation on recent and fossil taxa. The resulting tre...
Article
Full-text available
Heterochronic development has been proposed to have played an important role in the evolution of echinoderms. In the class Ophiuroidea, paedomorphosis (retention of juvenile characters into adulthood) has been documented in the families Ophiuridae and Ophiolepididae but not been investigated on a broader taxonomic scale. Historical errors, confusin...

Four species of brittle star are known to be associated with chemosyntheic environments, two of them are restricted to hydrothermal vents, one to methane seeps and one species occurs at both vents and seeps. The genus Ophiambix appears to be related to sunken wood or other chemosynthetic environments. Four species are currently known, but an undesc...

Cryptic species are numerous in the marine environment. The brittle star Ophioderma longicauda is composed of six mitochondrial lineages, encompassing brooders, which form a monophyletic group, and broadcasters, from which the brooders are derived. To clarify the species limits within O. longicauda, we compared the reproductive status of the sympat...

Owing to the assumed lack of deep-sea macrofossils older than the Late Cretaceous, very little is known about the geological history of deep-sea communities, and most inference-based hypotheses argue for repeated recolonizations of the deep sea from shelf habitats following major palaeoceanographic perturbations. We present a fossil deep-sea assemb...

Brittle stars (Echinodermata: Ophiuroidea) comprise over 2, 000 species, all of which inhabit marine environments and can be abundant in the deep sea. Morphological plasticity in number and shape of skeletal parts, as well as variable colors, can complicate correct species identification. Consequently, DNA sequence analysis can play an important ro...
