The movement of the hard drive's read/write heads over different areas of the disk when accessing fragmented files is slower, compared to accessing the entire contents of a non-fragmented file sequentially without moving the read/write heads to seek other fragments.
The giant oceanic manta ray can grow to a disc size of up to 7 m (23 ft) with a weight of about 1,350 kg (2,980 lb) but average size commonly observed is 4.5 m (15 ft). It is dorsoventrally flattened and has large, triangular pectoral fins on either side of the disc.
Both native and introduced species of Praying mantis are quite large, some over 3 to 4 inches long. The body is tarnish-brown with the longitudinal forewing's outer margins edged in a pea green color. The forelegs are modified to close like a knife blade back against its handle (pocket knife-like).
