Global biodiversity of the genus Ommastrephes (Ommastrephidae: Cephalopoda): an allopatric cryptic species complex
(Oxford University Press (OUP), 2020-03-20)
Cryptic speciation among morphologically homogeneous species is a phenomenon increasingly reported in cosmopolitan marine invertebrates. This situation usually leads to the discovery of new species, each of which occupies ...
The invasive land flatworm Obama nungara (Platyhelminthes: Geoplanidae) reaches a natural environment in the oceanic island of São Miguel (Açores)
(Magnolia Press, 2020)
We report a new finding of the invasive land flatworm Obama nungara Carbayo et al., 2016 in a natural reserve of the oceanic island of São Miguel (Açores, Portugal) at 947 meters of altitude. This is the first record for ...
First record of the elusive oceanic squid Thysanoteuthis rhombus Troschel, 1857 (Cephalopoda: Thysanoteuthidae) in the Catalan coast
(Consejo Superior de Investigaciones Científicas, 2021)
The diamondback squid Thysanoteuthis rhombus Troschel, 1857 is a large and elusive oceanic squid spe- cies. Here, we provide the first record of the species for the Catalan coast and integrate this finding in the current ...
Potentially handicapped but otherwise functional: Malformations in prey capture tools show no impacts on octopus life
(Wiley, 2020-10-17)
Larval mortality is a keystone ecological factor for many benthic octopus since it mostly occurs before their settlement in the sea bottom as benthic juveniles. The literature had revealed that records of adult animals ...
El globito de Cthulhu: una nueva joya del Mediterráneo
(Quercus, 2021-03)
[No abstract available]
Is cryptic biodiversity a common phenomenon among Atlantic oceanic squids?
(MDPI, 2021-03-13)
Historically, marine oceanic open environments have been considered without barriers to dispersal, and the subsequent speciation of lineages from distant areas. As a consequence, many marine pelagic marine invertebrates ...
Towards an eDNA assay for decapodiform cephalopods
(Pensoft, 2021-03-04)
Assessing the distribution and diversity of cephalopods using traditional approaches(standard fishing, market collection, and DNA barcoding) is time-consuming. EnvironmentalDNA (eDNA) assays are non-invasive, fast, and can ...
Morphological and molecular assessments of bobtail squids (Cephalopoda: Sepiolidae) reveal a hidden history of biodiversity
(Frontiers Media, 2021-01-20)
Molecular species delimitation assists taxonomic decisions for challenging species, like cryptic species complexes. Bobtail squids (Family Sepiolidae Leach, 1817) are a very diverse group of benthic and nektonic small to ...
Born with bristles: New insights on the Kölliker’s organs of Octopus skin
(Frontiers Media, 2021-05-10)
The entire skin surface of octopus embryos, hatchlings and juveniles bears scattered
tufts of tiny chitinous setae within small pockets, from which they can be everted and
retracted. Known as Kölliker’s organs (KO), they ...
