Article
Full-text available
The Yucatán Peninsula, Mexico is a carbonate platform well-known for extensive karst networks of densely stratified aquifer ecosystems. This aquifer supports diverse anchialine fauna, including species of the globally distributed anchialine shrimp genus Typhlatya (Atyidae). Four species (T. campecheae, T. pearsei, T. dzilamensis and T. mitchelli) a...

Full-text available
Annelids are predominantly found along with the seafloor, but over time have colonized a vast diversity of habitats, such as the water column, where different modes of locomotion are necessary. Yet, little is known about their potential muscular adaptation to the continuous swimming behaviour required in the water column. The musculature and motili...

The Yucatán Peninsula, Mexico is a carbonate platform well-known for extensive karst networks of densely stratified aquifer ecosystems. This aquifer supports diverse anchialine fauna, including species of the globally distributed atyid shrimp genus Typhlatya. Four species (T. campecheae, T. pearsei, T. dzilamensis and T. mitchelli) are endemic to t...
Article
Holopelagic animals were long assumed to have widespread geographic distributions due to the failure to recognize hydrographic species' barriers in the open ocean. As molecular genetic tools are more commonly used to study the ocean's inhabitants, diversity is found to be substantially higher than when inferred from morphological taxonomies alone....
Article
Full-text available
A new genus and species of Nerillidae, Nipponerilla irabuensis gen. nov., sp. nov., is described from an anchialine cave in Shimoji Island, west of Irabu Island (Miyako Islands, Southwestern Japan). Its morphology was examined with light, scan- ning electron, and confocal laser scanning microscopy. This new species, along with two putative new cave...
Article
Full-text available
Remipedia is a stygobitic group commonly associated with coastal anchialine caves. This class consists of 12 genera, ten of which are found within the Lucayan Archipelago. Herein, we describe a new species within the genus Godzillius from Conch Sound Blue Hole, North Andros Island, Bahamas. Godzillius louriei sp. nov. is the third known remipede ob...
Article
Full-text available
Across Annelida, accessing the water column drives morphological and lifestyle modifications-yet in the primarily "benthic" scale worms, the ecological significance of swimming has largely been ignored. We investigated genetic, morphological and behavioural adaptations associated with swimming across Polynoidae, using mitogenomics and comparative m...

Full-text available
ECOLOGICAL TRAITS: Anchialine caves contain bodies of saline or brackish waters with subterranean connections to the sea. Since virtually all anchialine biota is marine in origin, these caves have a larger and more diverse species pool than underground freshwaters. The trophic network is truncated and dominated by heterotrophs (scavenging and filte...
Article
Full-text available
Lying at the southernmost point of the Lucayan Archipelago, the Turks and Caicos Islands are amongst the better studied localities for anchialine cave biodiversity. For nearly five decades, novel invertebrate fauna, comprised primarily of crustaceans, have been collected from these tidally influenced pools – but new findings are always on the horiz...
Article
Full-text available
DNA barcoding and population genetic studies have revealed an unforeseen hidden diversity of cryptic species among microscopic marine benthos, otherwise exhibiting highly similar and simple morphologies. This has led to a paradigm shift, rejecting cosmopolitism of marine meiofauna until genetically proven and challenging the “Everything is Everywhe...
Poster
Full-text available
This poster summarizes the main results found regarding the meiofauna of caves in the western zone of Cuba. The community of meiofauna studied is composed of few individuals and has a low divergence of taxa. The nematodes showed a set of biological traits that suggest adaptations to a medium where food is scarce.
Conference Paper
Full-text available
The potential of subterranean environments as models to address major evolutionary and ecological questions has been highlighted in the literature. They represent partially isolated, discrete units offering several replicates of the same evolutionary processes. Species occurrence data of these environments is abundant, although sparse in the litera...
Article
Anchialine caves have revealed a variety of highly adapted animals including several records of nerillid annelids. However, only one stygobitic lineage, Speleonerilla nom. nov. (previously known as Longipalpa), seems obligate to this environment. We here provide new information on this lineage including the description of three new species, two new...
Article
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. He...
Article
Full-text available
We describe two new species of the annelid genus Trilobodrilus Remane, 1925 (Dinophilidae Verill, 1892) from an intertidal and a subtidal location in San Diego, California. These two species show morphological and molecular divergences between each other and the previously described, geographically distant species. Intertidal T. windansea sp. nov....
Article
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 inc...
Article
The diversity and ecology of meiofauna in caves is largely unknown. Therefore, we studied one anchialine and five freshwater caves in November 2014 and January 2016 in western Cuba. We recorded 10 invertebrate taxa with the most abundant being: Nematoda, Ostracoda, Acari and Copepoda. The meiofauna communities in the caves were relatively impoveris...
Chapter
The island of Lanzarote is situated in the northern end of the Canary Islands and hosts one of the most diverse volcanic anchialine ecosystems in the world. Best known for Túnel de la Atlántida, Lanzarote has a diverse set of anchialine habitats, including lakes, pools, and even wells that penetrate into the subterranean aquifer. The porous nature...

Pisione is a scaleless group of small scale worms inhabiting sandy bottoms in shallow marine waters. This group was once considered rare, but now 45 described species can be characterized, among others, by their paired, segmental copulatory organs (one to multiple external pairs), which display a complexity of various accessory structures. The evol...
