Abstract
The 'broad-headed' larval morph is cannibalistic and has a wider head and enlarged vomerine teeth compared with typical larvae. Broad-headed morphs occurred in both sexes and most of their diet was other salamanders. A variety of invertebrates comprised the remainder of their diet. Typical morphs ate primarily macroinvertebrates and plankton, and rarely (1 of 170 larvae analyzed) conspecifics. Young typical larvae consumed a narrow range of prey, mostly plankton, compared with older larvae, which consumed a diversity of macroinvertebrates in addition to plankton. 'Cannibalistic' versus 'typical' refers to a predilection and is not an absolute categorization. -from Authors
