Scientific Details

Meristics.

Anal fin spines/rays: 31-36
Caudal fin rays: 12
Pectoral fin rays: 12-14
Vertebrae: 20

Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Order level detail.
The Tetraodontiformes is a very diverse and specialized group of bony fishes that share the loss, reduction or fusion of many bony structures in the head and body. Fins and their supporting elements are reduced or lost, and vertebrae are reduced in number. They have small mouths with modified teeth that may be enlarged or fused into a beak-like structure, or incorporated into the jaw bones. The gill opening is reduced to a small slit near the pectoral-fin base, and most have thick skin, covered in scales that are modified into spines, ossicles or fused bony plates. Some groups are poisonous, and the puffers and porcupinefishes are highly inflatable. Puffers adn their allies are found worldwide in temperate and tropical seas, and a few species enter freshwaters.

Family level detail.
Members of the Family Monacanthidae are small to moderate sized mostly deep-bodied, compressed fishes with oval to circular bodies, tough leathery skin covered in rough spines, a prominent depressible spine over the eye that can locked in an upright position by a tiny second dorsal-fin spine. They also have a small mouth and gill slit, and long-based soft dorsal and anal fins. Pelvic fins are either absent, or reduced to a bony element fused to the rear of the pelvic bone.
