“…Metridium senile exhibits both sexual and asexual reproduction through pedal laceration. The species is an oviparous broadcast spawner, undergoing external fertilization upon release of gametes in late summer to early fall to produce free-swimming planula larvae (Bucklin 1982 ; Lombardi and Lesser 2010 ). Although an exact length of time that these larvae are able to exist planktonically is unknown, they are believed to stay in this stage for several months, being readily dispersed or carried over long distances to new habitat (Gemmill 1920 ; Hoffmann 1987 ).…”

“…Although an exact length of time that these larvae are able to exist planktonically is unknown, they are believed to stay in this stage for several months, being readily dispersed or carried over long distances to new habitat (Gemmill 1920 ; Hoffmann 1987 ). The more common method of reproduction is asexual reproduction by pedal laceration, which can occur in all individuals, at all times of year, and lead to dense clonal groups (Hand 1956 ; Hoffmann 1987 ; Lombardi and Lesser 2010 ; Glon et al 2019 ).…”

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.
