Venus flytrap

Defined open-trap length: 3 cm; defined specimen; range 2 cm–4 cm.

A defined mature Venus flytrap leaf with a 3 cm open trap. The calibrated length spans one trap, not the whole plant; cultivar and growing conditions affect size.

Defined examples — our methodology

The marked defined open-trap length is calibrated. Unmeasured illustration details are representative.

UK £2 coin

Specified diameter: 2.84 cm; specified.

Bimetallic UK two-pound circulation format: 28.4 mm diameter, 2.5 mm thickness and 12 g mass. Bimetallic means an outer ring and inner disc; earlier single-metal or collector issues are not the comparison input.

Royal Mint — bimetallic £2 specifications

The marked specified diameter is calibrated. Unmeasured illustration details are representative.

Why this measurement?

Why we use 3 cm

We compare the open-trap length of a Venus flytrap. This is an illustrative comparison value, not a claim that every example is the same. The recorded range is 2 cm to 4 cm.

The marked vertical span follows the measured feature, not the edges of the image. How calibrated comparisons work →
