Regeneration of the larval sea star nervous system by wounding induced respecification to the Sox2 lineage [PDF]
eLife, 2022 The ability to restore lost body parts following traumatic injury is a fascinating area of biology that challenges current understanding of the ontogeny of differentiation.

Two decades of change in sea star abundance at a subtidal site in Puget Sound, Washington. [PDF]
PLoS ONE, 2023 Long-term datasets can reveal otherwise undetectable ecological trends, illuminating the historical context of contemporary ecosystem states. We used two decades (1997-2019) of scientific trawling data from a subtidal, benthic site in Puget Sound ...

Lineage tracing shows that cell size asymmetries predict the dorsoventral axis in the sea star embryo [PDF]
BMC Biology, 2022 Background Cell size asymmetries are often linked to cell fate decisions, due to cell volumes and cell fate determinants being unequally partitioned during asymmetric cell divisions.

Sea star inspired crawling and bouncing [PDF]
Journal of The Royal Society Interface, 2020 The oral surface of sea stars is lined with arrays of tube feet that enable them to achieve highly controlled locomotion on various terrains. The activity of the tube feet is orchestrated by a nervous system that is distributed throughout the body without a central brain. How such a distributed nervous system produces a coordinated locomotion is yet to

Biology, 2022 To study how Odontaster validus can influence the spatial structure of Antarctic benthic communities and how they respond to disturbance, it is necessary to assess potential dietary shifts in different habitats. We investigated the diets of O.

Going deeper and further: a range and depth extension for the deep-sea feather star Paratelecrinus cubensis (Carpenter, 1881) (Comatulida, Atelecrinidae), first record from the Western Pacific [PDF]
ZooKeys, 2023 A specimen belonging to the deep-sea feather-star family Atelecrinidae was collected in April 2018 at the Kocebu Guyot at 1294 m deep. Based on its morphological characters, the specimen was identified as Paratelecrinus cubensis (Carpenter, 1881).

Proceedings of the National Academy of Sciences, 2014 In June of last year, researchers got the first report that sea stars in Washington’s Olympic National Park were succumbing to a new disease outbreak. By August, stars were falling off the rocks—dead by the thousands—at Vancouver Island. “That’s the point at which we started getting samples and alerting people,” says Drew Harvell, a marine ...

Eyes, Vision, and Bioluminescence in Deep-Sea Brisingid Sea Stars [PDF]
The Biological Bulletin, 2023 AbstractSea stars are a major component of the megabenthos in most marine habitats, including those within the deep sea. Being radially symmetric, sea stars have sensory structures that are evenly distributed along the arms, with a compound eye located on each arm tip of most examined species.

Diversity, 2016 Outbreaks of the crown-of-thorns sea star (Acanthaster planci) are likely to be strongly associated with drastic changes in larval survival influenced by food availability. However, no quantitative or qualitative data are available on the distribution of

Devastating Transboundary Impacts of Sea Star Wasting Disease on Subtidal Asteroids.
PLoS ONE, 2016 Sea star wasting disease devastated intertidal sea star populations from Mexico to Alaska between 2013-15, but little detail is known about its impacts to subtidal species. We assessed the impacts of sea star wasting disease in the Salish Sea, a Canadian
