Force in Newtons (N) required for a sea otter canine tooth (otter tooth) and California gull (CA-Gull) or Glaucous-winged gull (GW -Gull) beak, to penetrate new (A: black bars) and weathered (B: grey bars) PBR plastic. The plastic used was clear linear low-density polyethylene LLDPE. The weathered LLDPE was recovered from PBRs that had been exposed, floating in Moss Landing Harbor for 12 weeks. The overall mean puncture force was 78.6 N (±3.7, n = 40).
