Beadlet anemone  (Actinia equina)

Asexually: Of asexual reproduction: reproduction that does not involve the formation of sex cells (‘gametes'). In many species, asexual reproduction can occur by fission (or in plants ‘vegetative reproduction'); part of the organism breaks away and develops into a separate individual. Some animals, including vertebrates can develop from unfertilised eggs, this process, known as parthenogenesis gives rise to offspring that are genetically identical to the parent.
Brackish: Slightly salty water.
Larvae: Stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
Pelagic: Inhabits the open oceans.
