Tunicates primarily feed on small particles, including plankton and organic detritus, by filtering water through their bodies. They possess a siphon system that allows them to draw in water, trap food particles using a mucous net, and then expel the filtered water. This filter-feeding mechanism enables them to efficiently extract nutrients from their aquatic environment.
the hawsbill and leatherback sea turtle eats tunicates
Many species of the genus Pseudoceros, including P. ferrugineus, feed on colonial tunicates.
The scientific name for tunicates is Phylum Chordata, Subphylum Tunicata.
Tunicates are part of the phylum Chordata, and there are as many of 2,150 species of them. Sea stars, flatworms, and snails are some of the predators of tunicates.
chordates
Adult tunicates exhibit chordate affinities through the presence of a notochord in their larval stage, which is a defining characteristic of chordates. In larval tunicates, the notochord is prominent, along with a dorsal nerve cord and pharyngeal slits, which are features shared with other chordates. Although adult tunicates lose many of these traits and become sessile, they retain a structure called the tunic, which reflects their evolutionary connection to the chordate lineage. Overall, the larval form displays the key chordate features, while the adult form highlights the evolutionary adaptations of tunicates.
Because they have no back bone
Tunicates are invertebrates.
Cephalochordates e.g. Amphioxus ,; tunicates , acorn worms etc. are nonvertebrate chordates , they are collctively called protochordates .
No. They are both chordates, which means during embryonic development they have a notochord, the same as vertebrates. This does not persist in tunicates, but it does in lancelets (adults still have a notochord). Neither tunicates or lancelets have a backbone.
Green sea turtles eat sea grass and algae. They are mainly carnivorous as babies (they will eat fish) and adapt a more herbivorous diet as they age. Hawks bill sea turtles have jaws shaped to help them get food out of crevices in reefs. They eat squid, sponges, tunicates, shrimp, etc. Loggerhead sea turtles and the riddley sea turtles have more powerful jaws designed to crush. They eat crabs, mollusks, shrimp, jellyfish, and vegetation. Leatherback sea turtles eat soft bodied animals such as jellyfish, tunicates, etc.
They're filter feeders
