Trumpet anemone Aiptasia mutabilis Anemone Bruno intotheblue.it
Trumpet anemone (Aiptasia mutabilis Gravenhorst, 1831) is an antozoo belonging to the Aiptasiidae phylum cnidarians in the Mediterranean Sea and in the eastern Atlantic. It lives on rocky bottoms, in ravines or in the middle of algae.
It has several long and translucent tentacles used by the anemone to capture prey and to defend itself, through the emission of white stinging filaments called “aconzie”. The column is brown in color and the base is smaller in diameter, with which these invertebrates can be firmly anchored on a rock, or migrate in search of a safe place suitable for their needs.
It feeds on debris and, in the most adults and developed stages, also small fish. The sexes are separated and asexual reproduction occurs by division of the column.
Often unwanted guest of marine aquariums, due to its infesting behavior, Aiptasia is known for its particular speed of reproduction, which in captivity happens almost always asexually. Natural predators are some species of nudibranchs (Berghia verrucicornis), butterflyfish (Chelmon rostratus) and shrimps.
