Caulerpa is a genus of siphonal green algae from the class of Chlorophyceae living in tropical and subtropical seas. The term siphonal refers to algae, which consist of a single giant cell with many cell nuclei ( syncytium ). The tube-like or style-like body ( thallus ) carries leaf-like lobes, so-called phylloids. In addition, so-called rhizoids , root-like organs, which anchor the plant in the ground, emanatefrom the tube.
ecology
A native to the Indo -derived type , Caulerpa taxifolia , the so-called Killeralge, spreads massively in the Mediterranean and displaced by their rapid growth many plant and animal species. As far as is known, the caulerpas are the fastest growing algae in the world (up to 8 cm / day). In the meantime, the species Caulerpa racemosa , which migrated into the Mediterranean via the Suez Canal , is also being critically observed. It also spreads in the Mediterranean Sea and, in contrast to Caulerpa taxifolia , also reproduces sexually here.
Many species of the caulerpa are grazed by the gullet snails (Sacoglossa) on the sea floor. The snails ingest their chloroplasts and store them in their skin. The chloroplasts are then used as an energy source for some time. Such chloroplasts are called kleptoplastids . This is not a symbiosis because the chloroplasts are not passed on to the offspring. Other examples of kleptoplastids can also be found in some other snails and some dinoflagellates .
Some Caulerpa species are easy to cultivate in saltwater aquariums . Algae of this genus are kept together with seahorses in species aquariums , for example .
