Antennarius commerson is known as the giant frogfish, and large it is. I have seen specimens in Hawaii about the size of basketballs and nearly as round. Like many other species, they come in a variety of colors. Most of these photos are from Hawaii, taken in the late 1970s.
The largest ones I've seen have had the color pattern below.
The yellow one below is uncertain. It was small, more the typical size of Antennarius pictus, but it did not seem to have the correct pattern.
