Hunting by scent
Animals which hunt by scent include:
- Humans, see tracking (hunting), often with the aid of scent hounds
- Mosquitos, some of which appear to be particularly attracted to human odours[1][2]
- Snakes including the Eastern diamondback rattlesnake[3] and the Cape file snake
- Ocelots
Winghead sharks have long, widely spaced nostrils
- Sharks such as Winghead sharks[4] and Dog sharks[2] Some sharks react to the time difference between an odour reaching each nostril, enabling them to estimate the direction of their prey. This may be a factor in the development of widely-space nostrils in hammerhead sharks.[2]

Venomous snakes may follow the scent trail of bitten prey
