Recent studies have shown that coastal and shelf cephalopod populations have increased
globally over the last six decades. Although cephalopod landings are dominated by the …

We report two Arctic species of incirrate octopods new to science. One is formally described
here as Muusoctopus aegir Golikov, Gudmundsson & Sabirov sp. nov. while the other …

Does warmth from hydrothermal springs play a vital role in the biology and ecology of
abyssal animals? Deep off central California, thousands of octopus (Muusoctopus robustus) …

Within the context of global climate change and overfishing of fish stocks, there is some
evidence that cephalopod populations are benefiting from this changing setting. These …

Cryptic species complexes represent an important challenge for the adequate
characterization of Earth's biodiversity. Oceanic organisms tend to have greater …

Coleoids are the most diverse group of cephalopod mollusks. While their origin is date
during the Mesozoic, the diversification pattern is unknown. However, two hypotheses have …

Here, we evaluate the so-called Thorson's rule, which posits that direct-development and
larger eggs are favored toward the poles in marine organisms and whose validity been the …

Deep-water emergence (DWE) is the phenomenon where marine species normally found at
great depths (ie, below 200 m), can be found locally occurring in significantly shallower …

The taxonomy of Bathypolypus and Muusoctopus has long been confounded by poor
original descriptions and difficulty in distinguishing among species morphologically. We …

The chiton genus Tonicia is composed of 12 species, 11 of which are found in the eastern
Pacific, but the taxonomic status and geographical distribution of these species have long …
