subfamily

The new findings challenge that view, offering strong evidence that the Podonominae subfamily most likely began in the Southern Hemisphere and later expanded worldwide.

The subfamilies are major subdivisions of the family, while the tribes and subtribe can contain one or more of genera, which is the classification level just above the species.

Kane hopes that the vaccine strategy his team identified can be applied to other viruses -- other coronavirus subfamilies as well as other viruses such as influenza viruses.

This subfamily of snakes is usually harmless to humans and survives on a wide range of foods -- from larger creatures like birds, lizards and frogs to smaller, slimier prey like frog eggs, worms and slugs.

Even the assignment to the subfamily Larentiinae is not entirely secure and is based on a few features like wing venation.
