Fer-de-Lance paramyxovirus Ferlavirus, also referred to as Ophidian paramyxovirus, is a genus of viruses in the family Paramyxoviridae, order Mononegavirales.

There is currently only one species in this genus (Reptilian ferlavirus) to accommodate a single virus, Fer-de-Lance virus (FDLV).

[4] Ferlaviruses produce virions that are enveloped, with spherical geometries.

Ferlavirus genome is linear and around 15 kb in length.

The virus exits the host cell by budding.
