Microbial dysbiosis precedes signs of sea star wasting disease in wild populations of Pycnopodia helianthoides

open access: yesFrontiers in Marine Science, 2023
Sea star wasting (SSW) disease, a massive and ongoing epidemic with unknown cause(s), has led to the rapid death and decimation of sea star populations with cascading ecological consequences.

Feeding Ecology of Odontaster validus under Different Environmental Conditions in the West Antarctic Peninsula

open access: yesBiology, 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.

Bindin from a sea star [PDF]

open access: yesEvolution & Development, 2009
SUMMARY The genetic basis for the evolution of development includes genes that encode proteins expressed on the surfaces of sperm and eggs. Previous studies of the sperm acrosomal protein bindin have helped to characterize the adaptive evolution of gamete compatibility and speciation in sea urchins.

Sea stars generate downforce to stay attached to surfaces

open access: yesScientific Reports, 2021
Intertidal sea stars often function in environments with extreme hydrodynamic loads that can compromise their ability to remain attached to surfaces. While behavioral responses such as burrowing into sand or sheltering in rock crevices can help minimize ...

Live imaging of echinoderm embryos to illuminate evo-devo

open access: yesFrontiers in Cell and Developmental Biology, 2022
Echinoderm embryos have been model systems for cell and developmental biology for over 150 years, in good part because of their optical clarity. Discoveries that shaped our understanding of fertilization, cell division and cell differentiation were only ...

Practical Euthanasia Method for Common Sea Stars (Asterias rubens) That Allows for High-Quality RNA Sampling

open access: yesAnimals, 2021
Sea stars in research are often lethally sampled without available methodology to render them insensible prior to sampling due to concerns over sufficient sample quality for applied molecular techniques.

Sea star wasting [PDF]

open access: yesProceedings 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 ...

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]

open access: yesZooKeys, 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).

Kinematics of sea star legged locomotion

open access: yesJournal of Experimental Biology, 2021
ABSTRACT Sea stars have slower crawling and faster bouncing gaits. Both speed and oscillation amplitude increase during the transition from crawling to oscillating. In the bouncy gait, oscillating vertical velocities precede oscillating horizontal velocities by 90 deg, as reflected by clockwise circular hodographs.
