Sea star wasting disease demography and etiology in the brooding sea star Leptasterias spp. [PDF]
PLoS ONE, 2019 Sea star wasting disease (SSWD) describes a suite of disease signs believed to have led to catastrophic die-offs in many asteroid species, beginning in 2013. While most studies have focused on large, easily visible sea stars with widely-dispersing larvae,

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.

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 ...

Sea star inspired crawling and bouncing. [PDF]
J R Soc 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

Gecko adhesion based sea star crawler robot
Frontiers in Robotics and AI, 2023 Over the years, efforts in bioinspired soft robotics have led to mobile systems that emulate features of natural animal locomotion. This includes combining mechanisms from multiple organisms to further improve movement.

Interspecies comparison of sea star adhesive proteins. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2019 Sea stars use adhesive secretions to attach their numerous tube feet strongly and temporarily to diverse surfaces. After detachment of the tube feet, the adhesive material stays bound to the substrate as so-called ‘footprints’. In the common sea star species Asterias rubens , the adhesive material has been studied ...

RNA expression and disease tolerance are associated with a “keystone mutation” in the ochre sea star Pisaster ochraceus [PDF]
PeerJ, 2017 An overdominant mutation in an intron of the elongation factor 1-α (EF1A) gene in the sea star Pisaster ochraceus has shown itself to mediate tolerance to “sea star wasting disease”, a pandemic that has significantly reduced sea star populations on the ...

Impact of the extinct megaherbivore Steller's sea cow (Hydrodamalis gigas) on kelp forest resilience
Frontiers in Ecology and Evolution, 2022 Giant kelp forests off the west coast of North America are maintained primarily by sea otter (Enhydra lutris) and sunflower sea star (Pycnopodia helianthoides) predation of sea urchins.
