I tried a search, and have asked similar questions about the vision of Royal pythons, but I am more curious how it relates to boas.
Most of the pythons have visible heat pits and they use them very effectively to track and ambush their prey. In the case of the Royal python, it's noted that their vision is not particularly good but they are able to see.
Boas, BCI/BCC lack the visible heat pits but have incredible feeding responses and have been said to hunt by ambush and actively seeking prey. Though primarily nocturnal, they are also know to be out and about by day.
The several books I've read about the larger constrictors do not go into great detail about the Jacobson's organ or whether its more refined in boa without heat pits.
I'm wondering if anybody really knows if boas have better vision than the snakes with the heat pits, or if their Jacobson's organ is more refined.
The colubrids without heat pits, like the king can actually sight hunt.
Are there any science/biology herp folks out there that can shed light on this?
