Speckled smooth-hound Speckled smooth-hound The speckled smooth-hound ("Mustelus mento") is a houndshark of the family Triakidae. It is found on the continental shelf of the eastern Pacific, between latitudes 0° and 54° S, at depths between . It can reach a length of . Collectively with certain other species of shark, it is known as "tollo". The speckled smooth-hound is a robust shark with a moderately long, blunt snout, small eyes, short mouth and molar-like teeth without cusps. The trailing edge of the dorsal fins have small, pointed projections. The pectoral fins are large and the pelvic fins moderately large. The caudal
Smooth scheme only if the morphism "X" → Spec "k" is smooth. A smooth scheme over a field is regular and hence normal. In particular, a smooth scheme over a field is reduced. Define a variety over a field "k" to be an integral separated scheme of finite type over "k". Then any smooth separated scheme of finite type over "k" is a finite disjoint union of smooth varieties over "k". For a smooth variety "X" over the complex numbers, the space "X"(C) of complex points of "X" is a complex manifold, using the classical (Euclidean) topology. Likewise, for a smooth variety
