microCT dataset of cybertype/paratype - Caymanostella scrippscogniticausa / SMF 6939
<p>A specimen (SMF 6939) fixed in glutaraldehyde and OsO4 and preserved in 70% EtOH was scanned using a Werth Tomoscope® XS Plus 200 microCT with the following scan parameters: 85 kV voltage, 188 µA generator current, 16 W generator power. Exposure time was 500 ms with a total of 4200 projections (3 projections were averaged). The voxel resolution is 5.65 µm. Surface renderings were generated with the software Drishti v3.1.

Figure 7 in New record of the wood-associated sea star Caymanostella, with notes on the phylogenetic position of the family Caymanostellidae (Asteroidea)
Figure 7. Bayesian inference (BI) 50%-majority rule consensus tree. The analysis was based on the concatenated 3208- bp long dataset that included three mitochondrial (12S rRNA, 16S rRNA, COI) and two nuclear (18S rRNA, early stage H3 histone) markers. Branch support values are given from the BI (posterior probabilities)/ML (bootstrap percentage, 750 bootstrap replicates). The tree was artificially rooted between Velatida + Peripodida clade and other asteroid taxa. Ordinal names (at the right) are abbreviated as follows: BRIS, Brisingida; FOR, Forcipulatida; PER, Peripodida; N, Notomyotida; PAX, Paxillosida; SP, Spinulodida; VAL, Valvatida; VEL, Velatida. Familial names (aligned with the species names) are abbreviated as follows: Act, Acanthasteridae; Arch, Archasteridae; Asn, Asterinidae; Asp, Astropectinidae; Asps, Asteropseidae; Ast, Asteriidae; Bent, Benthopectinidae; Bris, Brisingidae; Cay, Caymanostellidae; Cht, Chaetasteridae; Cten, Ctenodiscidae; Ech, Echinasteridae; Fre, Freyellidae; Gan, Ganeriidae; Gon, Goniasteridae; Gop, Goniopectinidae; Hel, Heliasteridae; Kor, Korethrasteridae; Lei, Leilasteridae; Lu, Luidiidae; Mit, Mithrodiidae; Myx, Myxasteridae; Odt, Odontasteridae; Oph, Ophidiasteridae; Ore, Oreasteridae; Ped, Pedicellasteridae; Por, Poraniidae; Porc, Porcellanasteridae; Pse, Pseudarchasteridae; Pter, Pterasteridae; Sol, Solasteridae; Stich, Stichasteridae; Xyl, Xyloplacidae; Zor, Zoroasteridae.
