Conus (Leporiconus) coffeae & more on blue cone pigments
I went looking for more cone species that had blue pigmented siphonal canals & found 3: another form of Conus (Lividiconus) muriculatus & 2 species in subgenus Leporiconus: Conus (Leporiconus) glans (which I have already posted about) & very surprisingly an example in in the apparently highly variable species Conus (Leporiconus) coffeae, which I have also already posted about. A recently acquired specimen of C. coffeae showed almost completely black pigmentation. But the one I acquired tonight (pix below) has much less black pigmentation & a bright blue base. If the blue region is indeed involved with heat exchange & thermoregulation, the formation of the blue pigmented bases in these species could be the result of adaptation to different environments.
I'm now interested in trying to find out how closely these 2 subgenera are related both genetically & geographically. |
