What kind of skeleton do urochordates have?
Support: Hydrostatic skeleton (notochord in larval forms only). Digestive System: Large pharynx with many gill slits (stigmata) for filter-feeding; food trapped in mucus; food tube short and simple, often U-shaped with anus near atrial siphon.
Do urochordates have an endoskeleton?
The phylum Chordata has three Subphyla, the Urochordata, the Cephalochordata and the the Vertebrata. Only the first two are invertebrates. The chordata have an endoskeleton so they can grow continuously without moulting.
Do tunicates have a skeleton?
Although tunicates are invertebrates (animals without backbones) found in the subphylum Tunicata (sometimes called Urochordata), they are part of the Phylum Chordata, which also includes animals with backbones, like us. That makes us distant cousins.
What are the features of subphylum Urochordata?
Characteristics of Urochordata:
- Possesses a Notochord, a hollow nerve cord and a post anal tail.
- Body has more than two cell layers and includes tissues and organs.
- Has a U shaped gut.
- Body has no coelomic body cavity.
- Body wholly enclosed in a ‘tunic’ of secreted protein and cellulose-like material.
