     But the largest of the star-fish kind is that sea monster called kruken, kraken or krabben. [...] As this enormous sea-animal in all probability may be reckoned of the polype, or of the star-fish, kind, it seems that the parts which are seen rising at its pleasure, and are called arms, are properly the tentacula, or feeding instruments, called horns as well as arms.
