title: Respiratory tree of Holothuria leucospilota unexposed to  microplastic-contaminated seawater - Replicate 1
design: The objectives are to assess the effects of micro- and nanoplastics on the physiology of Holothuria leucospilova. After this species was exposed to micro- and nanoplastic-contaminated seawater for 14 days, respiratory tissue was collected to assess transcriptional changes.
