Abstract

The present note aims to provide detailed information on the biology and ecology of two marine heterobranch species belonging to the order Umbraculida: Umbraculum umbraculum and Tylodina perversa. The observations were carried out through scuba dives from 2017 to May 2022 in 5 sites located along the central-eastern coast of Sicily. For each species, information on the morphology, abundance, bathymetric range, substrates and habitats, seasonality, and further remarks were here provided. Through this research, it was noted that along the central-eastern coast of Sicily, T. perversa has never been found on sponges of the genus Aplysina, its prey so far documented, but always on algal substrates. Regarding U. umbraculum, it was observed that it counts among the sponges of its diet also the poriferan C. crambe. Moreover, through this study, it was documented for the first time the breeding activity of U. umbraculum, never reported in detail.

本说明旨在提供关于两种属于小叶纲的海洋异枝物种的生物学和生态学的详细资料:小叶纲(Umbraculum Umbraculum)和小叶纲(Tylodina perversa)。研究人员于2017年至2022年5月在西西里岛中东部沿海的5个地点进行了水肺潜水观察。每个物种的形态、丰度、水深范围、底物和生境、季节性和进一步的备注都在这里提供。通过这项研究，我们注意到沿西西里岛的中东部海岸，从未在有记载的其猎物- - -海藓属的海绵上发现过反螺旋体，而总是在藻类基质上发现。关于U. umbraculum，我们观察到它在其饮食的海绵中也包括多孔动物C. crambe。此外，通过本研究，首次记录了从未被详细报道过的乌布兰的繁殖活动。

期刊介绍： Travaux du Muséum National d’Histoire Naturelle "Grigore Antipa" (The Journal of "Grigore Antipa" National Museum of Natural History) is an international, open access, peer-reviewed journal devoted to zoological research that is published biannually by the "Grigore Antipa" National Museum of Natural History from Bucharest (Romania). It publishes original research or review articles dealing with all aspects of general zoology (taxonomy, systematics, evolutionism, faunistics, zoogeography, palaeozoology, animal ecology, invasive species of animals, parasitism, biodiversity conservation). Also, some book reviews, anniversaries and obituaries of some personalities of science world can be accepted to be published in this journal. In the present, the only language accepted for this journal is English. The scope of the journal is to publish, disseminate and provide open access to the results of the original studies made in different zoological fields, in Romania and worldwide. Every submitted manuscript is subject to peer-review, being reviewed by at least two peers qualified to evaluate it. Distinguished authorities form the international advisory board which guarantees the high scientific profile of the journal.
