Karyotypes of three ascidians (chordata; Ascidiacea) from Korea [PDF]
Korean Journal of Biological Sciences, 2000 Cytogenetic features of three ascidian species were studied with specimens obtained from Korean coastal areas. The gonadal tissue was processed in order to obtain mitotic and meiotic chromosomes. The chromosome numbers of Amaroucium pliciferum turned out to be 2n=26 and n=13 with 2sm, 3st, 8t and Halocynthia roretzi to be 2n=16 and n=8 with 6m, 2t ...

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 63-82, January 2023., 2023 Abstract This review examines the presence and evolution of thyroid‐like systems in selected aquatic invertebrates to determine the potential use of these organisms in screens for vertebrate thyroid hormone axis disrupting chemicals (THADCs). Such a screen might support the phasing out of some vertebrate testing.
