Sponge Animals of the phylum Porifera

Sponges, the members of the phylum Porifera, are a basal Metazoa (animal) clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. The branch of zoology that studies sponges is known as spongiology.

Sesquiterpene any unsaturated hydrocarbon with structure that is a result of the assembling of three isoprene units

Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be acyclic or contain rings, including many unique combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids.

Spiro compound any chemical compound having one atom as the only common member of two rings

A spiro compound, or spirane, from the Latin spīra, meaning a twist or coil, is a chemical compound, typically an organic compound, that presents a twisted structure of two or more rings, in which 2 or 3 rings are linked together by one common atom, examples of which are shown at right.

Johannes Thiele (zoologist) curator and zoologist

Johannes Thiele, full name Karl Hermann Johannes Thiele was a German zoologist specialized in malacology. Thiele was born in Goldap, East Prussia. His Handbuch der systematischen Weichtierkunde is a standard work. From 1904 until his retirement in 1925 he was the curator of the malacological collection at the Museum für Naturkunde in Berlin. Thiele described more than 1.500 new species of molluscs; until today their types are deposited with the Museum of Natural History in Berlin. Especially important are his works on the Mollusca of the First German Antarctica Expedition and of the German Deep Sea Expedition aboard the vessel Valdivia.
