Catches of Atlantic sharpnose shark (Rhizoprionodon terraenovae) and

- that allows fishermen catching

"The narrow sub-second time window in which this bilateral detection causes the turn response corresponds well with the swimming speed and odour patch dispersal physics of our shark species," known as Mustelus canis or the

Sharks, state waters: 54-inch minimum for all sharks except Atlantic sharpnose, blacknose, bonnethead, finetooth, blacktip and
