Morphology and Settling Velocity of Sea Stars (Asterias rubens)
Autor: Karen B. Burgaard, Stefan Carstensen, David R. Fuhrman, Camille Saurel, Finbarr G. O’Neill
Publikováno v: Journal of Marine Science and Engineering, Vol 11, Iss 2, p 296 (2023)
This study presents morphological data and estimates of the settling velocity and drag coefficient of sea stars (Asterias rubens) caught in the Limfjord, Denmark. A geometric model describing the sea star is presented and the thickness and arm width
