Octocorals possess sclerites, small elements comprised of calcium carbonate (CaCO) that are important diagnostic characters in octocoral taxonomy. Among octocorals, sea pens comprise a unique order (Pennatulacea) that live in a wide range of depths. Habitat depth is considered to be important in the diversification of octocoral species, but a lack of information on sea pens has limited studies on their adaptation and evolution across depth.

Article Synopsis
  • - Understanding the transmission dynamics of SARS-CoV-2 is crucial for developing effective prevention strategies, with genome sequencing offering insights into infection pathways.
  • - A study analyzed 49 SARS-CoV-2 samples from local clusters in NW Spain, revealing that while genomic data generally aligned with epidemiological information, it struggled to definitively identify direct transmission events due to low levels of genetic variation.
  • - The research suggests that the ability to reconstruct direct SARS-CoV-2 transmission using genomic data is limited by a slow mutation rate and technical challenges, highlighting the need for detailed contact tracing to supplement genomic analyses.

A new species of Etelis is described based on 16 specimens collected from the Red Sea and Western Australia, with confirmed genetic records throughout the Indo-West Pacific. It is similar to and was often misidentified as Etelis carbunculus Cuvier, with both species sharing the diagnostic character of low number of developed gill rakers. Nonetheless, the two species are genetically divergent and differ morphologically in adult body length; proportions of eye, snout, cheek and caudal fin; shape of head, opercular spine and sagittal otolith; and coloration of the tip of the upper caudal fin.

is a widespread and common rocky intertidal cephalopod that mates readily in the laboratory, but for which mating behavior has not been reported previously. Four sets of behavioral experiments were recorded wherein three males, small, medium & large in varying order, were introduced to each of six females, for a total of 24 individual females and 12 individual males utilized in the experiments. Video analysis shows that successful mating occurred in each of the mount, reach and beak-to-beak positions.

Millepora (Cnidaria: Hydrozoa: Milleporidae) spp. are distributed throughout shallow subtropical and tropical marine environments in the Indo-Pacific and Caribbean-Atlantic, and have traditionally been identified using pore characteristics and colony form. Until now, representatives of Millepora spp.
