The shell size varies between 12 mm and 25 mm

Distribution

This species is endemic to the seas off the southern islands of New Zealand

gollark: No. You still only have one mean, which is going to be somewhere between the peaks.
gollark: Not *necessarily*, a distribution can have multiple peaks.
gollark: Equivalently, if you take a random person you know nothing about, the probability that their height is between, say, μ-3σ and μ-2σ (154cm to 164cm) is lower than the probability of it being between μ-2σ and μ-σ (164cm to 173cm).
gollark: The further away from the average height you get, the rarer people with that height are.
gollark: If you imagine plotting a bar graph with *extremely* narrow bars with all the information on heights you get, then the tops of the bars will form a shape like that.
