NOTE: For photography of later stage larvae, propylene phenoxytol (PP here =propylene glycol phenol ether; Dow Chemical) was combined with immobilization by compressing larvae under a cover slip. This did not work on early-stage larvae, which were relaxed in FASW containing 4% ethanol.

[Note: Other concentrations of AB were tested at various temperatures; higher concentrations were needed at lower treatment temperatures and vice versa; recovery from higher concentrations required temperatures lower than 20 oC.]

[Note: Isobutyl alcohol (IA) was less toxic than methyl pentynol; though other concentrations of IA were tested, the concentration range listed was recommended for routine use.]

[Note: the anesthetic agents enflurane, halothane, and isoflurane were also tested, and required higher concentrations than the methoxyflurane (MF) listed in the table.]

[Note: Injection was through posterior leg arthrodial membrane. Many other agents were tested on C. maenas or Cancer pagurus, C. maenas). Most other agents were ineffective, but alphaxolone (Saffan), pentobarbitone (Nembutal), propanidid (Epontal), and xylazine (Rompun) were also useful at 30, 250, 100, and 70 mg/kg, respectively.]

Coelenterates

[Note: AB, CH, ME, and MC were all tested on many species of anemones; each was more effective on some species than on others. The ME technique, for which one species is listed, was recommended by Moore as "one of the simplest and most effective."]

[Note on PP identity: O'Neill, 1994 states that the chemical identity of the "propylene phenoxetol" used in some earlier studies is uncertain, that PP is actually 1-phenoxy propane-2-ol according to the International Union of Pure and Applied Chemistry (IUPAC), and that this is the compound likely to have been obtained by various investigators from Nipa Laboratories, UK. According to Coney, 1993, if PP is not available, the related compound 2-phenoxyethanol is a good substitute.]

[Note on PP use: In Owen's original procedure, 5 ml propylene phenoxytol (from Nipa laboratories; see also Note on "propylene phenoxytol" identity) was shaken vigorously with 15-20 ml seawater. This produced a fine emulsion, which in turn was added to seawater in which there were actively siphoning animals. The final % (v/v) propylene phenoxytol in the diluted "emulsion" is not given. After 30 min, animals had gaping valves and a protruding foot, but they recovered upon return to fresh seawater. Many species were studied, of which three are listed in Table 1.]
