The bubble snails (Gastropoda, Heterobranchia) of Mozambique: an overlooked biodiversity hotspot
Tibiriça, Yara; Malaquias, Manuel Antonio E. (Peer reviewed; Journal article, 2016)This first account, dedicated to the shallow water marine heterobranch gastropods of Mozambique is presented with a focus on the clades Acteonoidea and Cephalaspidea. Specimens were obtained as a result of sporadic sampling ... -
Diet preferences of the Aglajidae: a family of cephalaspidean gastropod predators on tropical and temperate shores
Zamora, Andrea; Malaquias, Manuel Antonio E. (Peer reviewed; Journal article, 2015)Aglajidae is a family of tropical and temperate marine Cephalaspidea gastropod slugs regarded as active predators. In order to better understand their food habits and trophic interactions, we have studied the diet of all ... -
Diversity and systematics of Haminoeidae gastropods (Heterobranchia: Cephalaspidea) in the tropical West Pacific Ocean: New data on the genera Aliculastrum, Atys, Diniatys and Liloa
Too, Chin Chin; Carlson, Clay; Hoff, Patty Jo; Malaquias, Manuel Antonio E. (Peer reviewed; Journal article, 2014)Four genera of Haminoeidae gastropods inhabiting the tropical West Pacific (Aliculastrum, Atys, Diniatys, and Liloa) were studied based on the combined analyses of live animals, external morphology, anatomy and shells aided ... -
Diversity and systematics of philinid snails (Gastropoda: Cephalaspidea) in West Africa with remarks on the biogeography of the region
Malaquias, Manuel Antonio E.; Ohnheiser, Lena Tina; Oskars, Trond Roger; Willassen, Endre (Peer reviewed; Journal article, 2016)West Africa is often considered one of the least studied regions of the world concerning marine biodiversity. Knowledge about the philinid snails of the region has largely been based on shells, but shells can be insufficient ... -
Ecosystem alterations and species range shifts: An Atlantic-Mediterranean cephalaspidean gastropod in an inland Egyptian lake
Cruz-Rivera, Edwin; Malaquias, Manuel Antonio E. (Peer reviewed; Journal article, 2016-06)The eastern Atlantic and Mediterranean marine Cephalaspidea gastropod Haminoea orbignyana was collected from Lake Qarun (Fayoum, Egypt), a landlocked lake that has undergone a shift from freshwater to estuarine conditions ... -
Integrative taxonomy reveals a cryptic species of the nudibranch genus Polycera (Polyceridae) in European waters
Sørensen, Cecilie Gotaas; Rauch, Cessa; Pola, Marta; Malaquias, Manuel Antonio E. (Journal article; Peer reviewed, 2020)This work aimed to test whether the colour variability featured by the European nudibranch Polycera quadrilineata is consistent with the concept of a single polychromatic species or may hide multiple lineages. Samples from ... -
The mediterranean sea as a gateway for invasion of the red sea: The case of the indo-west pacific head-shield slug chelidonura fulvipunctata baba, 1938
Malaquias, Manuel Antonio E.; Zamora-Silva, Andrea; Vitale, Dyana; Spinelli, Andrea; De Matteo, Sergio; Giacobbe, Salvatore; Ortigosa, Deneb; Cervera, Juan L. (Peer reviewed; Journal article, 2016-04-07)The number of tropical species established in the Mediterranean Sea has risen at an unprecedented rate in the last 40–50 years, often entering the basin from the Red Sea and to a lesser extent by shipping or mariculture. ... -
A molecular phylogeny of the Indo-West Pacific species of Haloa sensu lato gastropods (Cephalaspidea: Haminoeidae): Tethyan vicariance, generic diversity, and ecological specialization
Oskars, Trond Roger; Malaquias, Manuel Antonio E. (Peer reviewed; Journal article, 2019-07-06)The cephalaspidean gastropod genus Haminoea has been considered a worldwide radiation with species living in intertidal and shallow areas with algae, seagrass sandy-mud, mangroves, and coral reefs. Recently this monophyletic ... -
A new phylogeny of the Cephalaspidea (Gastropoda: Heterobranchia) based on expanded taxon sampling and gene markers
Oskars, Trond Roger; Bouchet, Philippe; Malaquias, Manuel Antonio E. (Peer reviewed; Journal article, 2015-08)The Cephalaspidea is a diverse marine clade of euthyneuran gastropods with many groups still known largely from shells or scant anatomical data. The definition of the group and the relationships between members has been ... -
