The size of maternal eggs influence the sizes of larvae. The larvae from larger eggs will not only experience shorter time period on metamorphose than larvae from smaller eggs, but also grow larger.

Vocalization
Newts are mistakenly believed not to vocalize. Their vocalizations exhibit a wide frequency range from 1.4 kHz to 8 kHz, with varying duration times ranging from less than 0.1 second to 0.4 seconds.

The vocalizations of California newts are functional and are usually related to defense and sexual behaviors. They have three primary vocalizations: clicks, squeaks, and whistles. Clicks are most frequently produced, usually occurring in response to unfamiliar environments or confrontations. Squeaks are associated with defense behavior and may serve to startle predators, potentially reinforcing the recognition of the species as toxic. Whistles appear to be related to sex recognition or hierarchical interactions.
