Ian Lee feels for the pelvic fins on a dogfish shark on Friday at Colorado Center for the Blind. Students dissected dogfish sharks as part of their biology class.

“Yucks!” blended with yucks as the students probed the stomach contents of the dogfish sharks they were dissecting.

“I found a claw,” said one student, as he waved miniature pincers in the air.

“I found a fish,” another student said as she held high a half-digested fish body.
