Exempel på hur man kan använda ASCIDIANS i en mening

• Unlike their benthic relatives the ascidians, from which they are believed to have emerged, thaliaceans are free-floating (pelagic) for their entire lifespan.
• Their relationship with other tunicates remained unclear, with larvaceans being argued to be ascidian larvae or a free-swimming generation of ascidians.
• Ascidiacea, commonly known as the ascidians or sea squirts, is a paraphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders.
• thumbthumbThe solitary ascidian Herdmania momus is one of the most commonly encountered species of ascidians.
• The intertidal platforms have the highest invertebrate diversity of any calcarenite reef in Victoria, while subtidal areas are characterised by diverse and abundant algal communities as well as by encrusting organisms such as ascidians, sponges and bryozoans.
• The coast of Point Nepean contains intertidal reef platforms with high invertebrate diversity as well as subtidal reefs with diverse communities of fish, invertebrates and encrusting organisms such as ascidians, sponges Dale and bryozoans.
• It is a voracious predator, consuming bivalves, gastropod molluscs, barnacles, crustaceans, sea worms, echinoderms, ascidians, sea urchins, sea squirts and other seastars, including those of its own species if other supplies are exhausted.
• Most osmoconformers are marine invertebrates such as echinoderms (such as starfish), mussels, marine crabs, lobsters, jellyfish, ascidians (sea squirts - primitive chordates), and scallops.
• This nudibranch prefers to feed on tunicates (such as the sessile ascidians), but overall has a diverse diet, also consuming hydroids, anthozoans, crustaceans, other nudibranchs, dead animals, and the polyps of jellyfish (theoretically, they may also consume stranded adult jellyfish too, if accessible).
• The larvae of ascidians (sea squirts) contain a pair of sensory pigment cells known as the otolith and ocellus.
• For the bird's nest sponge associated species include ascidians, Foraminifera, polychaetes and burrowing anemones, whilst for the encrusting sponge beds species such as anemones, ascidians, crinoids and ophiuroids are found.
• The silted, rocky slopes in the inner areas of the loch support encrustations of algae and ascidians, giving way to more mixed muddier sediments in shallower waters.
• It is believed that thyroid hormones evolved in the Urbilaterian well before the development of the thyroid itself and molluscs, echinoderms, cephalochordates and ascidians all use such hormones.
• Hemovanadin is a pale green vanabin protein found in the blood cells, called vanadocytes, of ascidians (sea squirts) and other organisms (particularly sea organisms).
• Despite being one of the world's most conspicuous sea squirts, Pyura stolonifera is often confused with other, morphologically similar ascidians.
• perforatus it is often associated with sponges and encrusting red seaweeds on shady overhanging rocks and cave entrances and also bryozoans and ascidians in deeper shade.
• Osmoregulatory capabilities of three macrosympatric stolidobranch ascidians, Styela clava Herdman, S.
• Species in this order infect marine invertebrates — usually annelids, ascidians, hemichordates and sipunculids.
• Like other ascidians, they have two siphons (incurrent and excurrent), through which they draw water for ventilation and filter-feeding, and also for releasing their gametes.
• Berthella plumula is a slow moving predator which scrapes its radula on rocks to feed on colonial ascidians of the genus Botryllus as well as on Oscarella sponges.
