“…The essential difference is the presence of a circular, branched tunnel with a permanently dark area in which dwell animals with negative phototaxis and species not able to withstand wave action. Some species new to the Black Sea have recently been discovered here (Kovtun, 2010, 2012; Kovtun & Pronin, 2011a, b; Kovtun & Petriashev, 2012; Grebelniy & Kovtun, 2013). Tarzanka Cave shelters almost all the species of fish that live in the open waters of this area (personal observations).…”

The main objectives of this study are the establishment of a detailed description of five semi-submerged and shallow-water marine caves from the Tarkhankut Peninsula (Crimea), their biological characteristics with particular attention to species composition, and the distribution of sponge assemblages in these caves. Three semi-submerged and two submerged caves with lengths of 9–131 m and volumes of 61–3060 m3 have been investigated. All of them are karst-abrasive or karst in origin. In the investigated caves, we inventoried seven sponge species. All were recorded species of Porifera belong to the class Demospongiae and have previously been recorded also in adjacent open sea waters. These species are tolerant to different hydrological conditions, mostly temperature and salinity. Some of them have wide geographic distribution. The species composition of sponges from the shallow water caves of Crimea is quite different from the sponge composition in Mediterranean caves. This could be due to the geographic isolation of the Black Sea and the differences in the hydro-chemical parameters of the milieu (water salinity in Tarkhankut is 18–21‰).

“…The species is typically found in the low intertidal to subtidal attached to or in hard substrates, but can also be found at deeper depths to 90 m (Stephenson 1935 ). Relatively recent reports of large populations in the Black Sea (Grebelnyi and Kovtun 2013 ) may reflect a range expansion into that more brackish and highly disturbed system. Sagartia elegans reproduces both sexually and through pedal laceration (see Ates et al 1998 ; Shaw 1991 ; Grebelnyi and Kovtun 2013 ).…”

“…Sagartia elegans is a well-known northern European species reaching a height of 4.5 cm, inhabiting coastal and mildly brackish habitats from Scandinavia to North Africa (Fig. 5 ; Grebelnyi and Kovtun 2013 ). The species is typically found in the low intertidal to subtidal attached to or in hard substrates, but can also be found at deeper depths to 90 m (Stephenson 1935 ).…”

Mediators of invasions in the sea: life history strategies and dispersal vectors facilitating global sea anemone introductions

Widespread non-native species tend to demonstrate an apparent lack of selectivity in habitat requirements, feeding regimes, and reproductive needs, while displaying a tendency to thrive in human-modified habitats. The high phenotypic plasticity typical of sessile, substrate-attached marine species may enhance their chances of survival and spread in a new region. Anthropogenic activities have changed marine habitats over a wide range of phenomena, including water temperature, community species composition, and the types of available substrates, creating new physical and biotic regimes that may contribute to the potential for successful species introduction. Here we examine ten species of sea anemones that have been introduced outside of their native range, and elucidate specific characteristics that are common among globally introduced sea anemones. Various life history strategies enable these species to survive and flourish through transport, introduction, establishment and spread, leading to the successful colonization of a new geographic area. Considering life history strategies and weighing of vector potential, we suggest conditions that facilitate introduction of these species, and identify species of sea anemones that may be introduced in the future in the face of changing climate and increased anthropogenic activities.
