Wedge-shaped.
Industry:Natural environment
A body form of medium complexity in sponges where the body wall has become folded and the choanocytes (flagellated collar cells) are not located along the spongocoel, but along radial canals. Water enters the sponge through a series of incurrent canals and passes through internal pores called prosopyles into the radial canals, which are lined with flagellated choanocytes.- It is the action of these choanocytes that keeps water moving through the sponge. From the radial canals, water then enters the central spongocoel through pores called apopyles, to exit to the environment through a single opening, the osculum.
Industry:Natural environment
A distinct genetic form or variant of a particular species. For example, a distinct color phase of a species that exhibits more than one color .
Industry:Natural environment
A light-producing organ, found especially in marine fishes and cephalopods. Photophores emit light from intrinsic structures, or derive light extrinsically from symbiotic luminescent bacteria.
Industry:Natural environment
A pigment that efficiently absorbs light within the 400-700 nm range and is essential for photosynthesis.
Industry:Natural environment
A soft coral of the order Alcyonacea, class Anthozoa, phylum Cnidaria. They consist of a firm body, throughout which calcareous spicules are dispersed. The surface is studded with polyps. They are closely related to the scleractinian (hard or stony) corals but lack the rigid, stony exoskeleton.
Industry:Natural environment
A type of dentition where the teeth are not all similar. For example, a mixture for special functions, such as canines, incisors and molars for piercing and tearing, snipping and grinding .
Industry:Natural environment
An estimate based on a sample or samples of a population, providing an indication of the true population parameter.
Industry:Natural environment
Any species of spiny-rayed fishes in the family Fistulariidae. Cornetfishes are elongated, depressed-bodied fishes with a greatly extended tubular snout, a very small mouth, and a long thin filament extending from the middle of the caudal fin. They are closely related to the trumpetfishes (Aulostomidae) which are more robust and lack the caudal filament. At present there are approximately five known species of cornetfishes.
