@Euphanerops @ZoologyMuseum Yes, although that may be more than the venomous potential hasn't been investigated https://t.co/foUFzWO2pB
@GaryJMatthews While the presence of venom glands has not verified in all callichthyid catfishes such as Corydoras, they have in a few like Dianema shown here (vgc = venom gland cells and ps=pectoral spine). Figure from Wright 2009 and link to the publicat
@Pacificklaus While venom is widespread in catfishes, it may have evolved more than once according to Wright 2009. https://t.co/rrQrBElYAo
@scienceheart0 (自己レス)やはり有るのかなあ Wright, J.J. Diversity, phylogenetic distribution, and origins of venomous catfishes. BMC Evol Biol 9, 282 (2009). https://t.co/kAiISU12Vz (参照 2020-06-20)
This could be because, according to #Smith2016, catfish families have seen the most losses in the evolution of a venom apparatus in the phylogeny of fishes. Check out these articles for more info: https://t.co/5L6VOdn3Vk. https://t.co/qD7iCfcKhx #OCS4012 h
Toxic peptides in catfish venoms may have been derived from epidermal secretions meant to accelerate wound healing: http://t.co/DouoEMbk
