The brittle star Ophiothela cf. mirabilis, an ophiuroid introduced in the Atlantic, has expanded its range north to Trinidad and Tobago and south to Paraná, Brazil. By monitoring the coast of Santa Catarina, Brazil, with both recruitment plates in harbors and SCUBA diving, we were able to observe specimens of O. cf. mirabilis in both natural and anthropogenic habitats. This confirms its reported range extension of ~80 km south and emphasizes the importance of anthropogenic means for their spread and establishment.

Sampling Methods

Samples were made by SCUBA diving and also by installing recruitment granite plates in three harbors monitored along the state's coast.

Study Extent The study was conducted in harbors along the coast of Santa Catarina, Brazil, with monthly monitoring events over the year 2013.

Method step description:

  1. Recruitment granite plates were installed in three harbors across the Santa Catarina coast. There were five metal sets per locality, each with three 25 x 30 cm square granite plates attached, hung directly into the water by steel ropes so that during low tide they would still be at a minimum of 2 m underwater. During each monitoring event, the metal sets were lifted and placed in a container with seawater from the site, as photoquadrats were taken and further observations were made, with few collections and minimal alterations to the biota on the plates. Afterwards, plates were hung back into the water until the next monitoring event. SCUBA dives were also held across the state’s rocky shores. These dives were performed regularly, often more than once a month, and included not only the assessment of exotic and invasive species, but also the study of the benthic community and environmental variables monitored by data loggers. Five specimens from the São Francisco do Sul harbor were collected and analyzed under a stereomicroscope for identification. Posteriorly, these were fixed in 100% ethanol.
