Phlebobranchia
Phlebobranchia is a suborder of sea squirts in the class Ascidiacea. Characteristics The group includes both colonial and solitary animals. They are distinguished from other sea squirts by the presence of longitudinal vessels in the pharyngeal basket. This provides the etymology of their name: in ancient greek, means "blood vessel". Another characteristic of phlebobranchians is the gonads being surrounded by a loop of gut. The posterior part of the abdomen is absent, and many species also lack the epicardial cavity that surrounds the heart and other internal organs in many other sea squirts.

Tunicates
A tunicate is a marine invertebrate animal, a member of the subphylum Tunicata (). It is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords (including vertebrates). The subphylum was at one time called Urochordata, and the term urochordates is still sometimes used for these animals. They are the only chordates that have lost their myomeric segmentation, with the possible exception of the 'seriation of the gill slits'. Some tunicates live as solitary individuals, but others replicate by budding and become colonies, each unit being known as a zooid. They are marine filter feeders with a water-filled, sac-like body structure and two tubular openings, known as siphons, through which they draw in and expel water. During their respiration and feeding, they take in water through the incurrent (or inhalant) siphon and expel the filtered water through the excurrent (or exhalant) siphon. Most adult tunicates are sessile, immobile and perman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptia (genus)
The Crypteia, also referred to as Krypteia or Krupteia ( Greek: κρυπτεία ''krupteía'' from κρυπτός ''kruptós'', "hidden, secret"), was an ancient Spartan state institution involving young Spartan men. It was an exclusive element of Sparta's state-sponsored child-rearing system in which participation afforded its members, known as ''kryptai'' (κρύπται, members of the Krypteia), the opportunity to test their skills further and to prove themselves worthy of the Spartan polity. As an organisation, the Crypteia's mandate and practices are still debated by historians. Overview The Crypteia had young Spartan men, probably between the ages of 21 and 30, who were described as "those judged to have the most intelligence." The men were known as ''hêbôntes'', one of the many social categories that preceded full Spartiate citizenship, and had completed their rearing at the agoge with such success that they were marked out as potential future leaders by Spartan offic ...

Situla (genus)
Situla (plural ''situlae''), from the Latin word for bucket or pail, is the term in archaeology and art history for a variety of elaborate bucket-shaped vessels from the Iron Age to the Middle Ages, usually with a handle at the top. All types may be highly decorated, most characteristically with reliefs in bands or friezes running round the vessel. Decorated Iron Age situlae in bronze are a distinctive feature of Etruscan art in burials from the northern part of the Etruscan regions, from which the style spread north to some cultures in Northern Italy, Slovenia, and adjacent areas, where terms such as situla culture and situla art may be used. Situla is also the term for types of bucket-shaped Ancient Greek vases, some very finely painted. More utilitarian pottery situlae are also found, and some in silver or other materials, such as two glass ones from late antiquity in St Mark's, Venice. Ancient Egyptian and Near Eastern shapes tend to have a pointed bottom, so that they mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
