Bullseye Puffer, Concentric Puffer
Botete Diana
(Sphoeroides annulatus)

Bullseye Puffer, Sphoeroides annulatus: The Bullseye Puffer is easily identified by the striking pattern of concentric circles on its back.

Due to this unique marking, the Bullseye Puffer cannot be easily confused with any other species. The upper head and body are various shades of brown, gray, and white; the underside is pale.

The Bullseye Puffer's back and side are normally covered with numerous, very small dark brown spots, but the fins and belly are free of spots. It has an elongated snout.

This fish species is normally found over sandy bottoms but, does visit reefs and rock-sand interfaces on occasion, close to shore, in the first 40 feet of the water column. It reaches a maximum length of approximately 16 inches but is normally 8 to 12 inches.

It is a member the Tetraodontidae or Pufferfish Family.

Distribution in Mexico fishing areas

In Mexican fishing waters , the Bullseye Puffer is omnipresent in all near shore Mexican waters, but it appears to be absent from around the oceanic islands.

Note: Like many puffers, the Bullseye Puffer is reputed to be highly poisonous, even fatal, if eaten, due to the presence of tetrodotoxin believed to protect it from predation by larger fish.
