(Angel sharks) > Squatinidae

(See ETYFish); tergocellatoides: -oides, Greek suffix meaning like, resembling, having the form of: described as “closely allied” to S. tergocellata but with a different color pattern, much longer tail, more numerous snout tubercles, and no medial series of dorsal tubercles. (See ETYFish).
