Which subgroup does the Blobfish belong in?

The Blobfish belongs to the subgroup of fish known as Opisthoproctidae, commonly referred to as the fathead sculpins. These fish are characterized by their gelatinous bodies and are typically found in deep-sea habitats off the coasts of Australia and New Zealand. Blobfish are particularly noted for their unique appearance, which becomes more pronounced when they are brought to the surface due to the change in pressure.
