Has toxic effects on zebrafish larvae (PubMed:31134275). It causes contractile paralysis and twitching of the tail within 30 minutes, followed by death within 40 minutes (PubMed:31134275). Does not show any toxicity when injected into arthropods (cherry shrimps or grass shrimps) (PubMed:31134275). Expressed in ectodermal gland cells (PubMed:31134275). In adult female tissues, highly transcribed in mesenteries (gametes-producing tissue) and slightly transcribed in tentacles, pharynx and physa (PubMed:31134275). Is detected in unfertilized eggs, late planulae, and primary polyps, but not in adults (both males and females) (at protein level). At mRNA level, is found at multiple developmental stages including unfertilized eggs, blastulae, gastrulae, early planulae, planulae, metamorphosing planulae, primary polyps, juvenile polyps (low levels at 4 months old, but no mRNA at 2 months), adult males, and adult females, with the highest levels from gastrulae to primary polyps, and adult females. Does not show activity on all ion channel tested at 10 uM (hNav1.1/SCN1A, rNav1.2/SCN2A, rNav1.3/SCN3A, rNav1.4/SCN4A, hNav1.5/SCN5A, mNav1.6/SCN8A, rNav1.8/SCN10A, BgNav1, Shaker IR, rKv1.1/KCNA1, rKv1.2/KCNA2, hKv1.3/KCNA3, rKv1.4/KCNA4, rKv1.5/KCNA5, rKv1.6/KCNA6, rKv2.1/KCNB1, hKv3.1/KCNC1, rKv4.3/KCND3, hKv7.2/KCNQ2, hKv7.3/KCNQ3, hKv10.1/KCNH1/EAG1, hKv11.1/KCNH2/ERG1).
