“…Larvae of many sea urchin species are often used as bioindicators in a variety of ecotoxicological and ecological studies. Thus, a wealth of data exists on various morphological abnormalities of sea urchins during embryonic and larval development caused by various pollutants and environmental stressors (see Gambardella et al, 2021; Lister et al, 2017; Sewell et al, 2021, and references therein). These abnormalities include cleavage disruption, developmental arrest, altered skeletogenesis, swollen larvae, and slow or asynchronous cilia beating.…”

Activation of the dopamine type-D 2 receptor in late gastrula of sea urchins is known to decrease the growth rate of post-oral arms of larvae, and, as a result, the phenotype of these larvae mimics that of larvae developing in the abundance of food. Our data indicate that the effect of dopamine on sea urchin larvae is stage-dependent. In our experiment, the early four-armed plutei (96 hours post fertilization, hpf) of Stron-
