Table 1. NOS activity in the host tissues of three cnidarian species.

Species	NOS activity (pmol citrulline x mg protein−1 ×30 min−1)
Acropora millepora	25.2* (±10)
Lobophytum pauciflorum	376.4* (±8)
Aiptasia pallida	8127.5* (±76)

Asterisks depict significant difference in NOS activity (Tukey-Kramer Test, α = 0.05). Values are means of 3 individual experiments (± SE).
