The most important loadings.
PCA, principal component analysis; PCA1, first axis; PCA2, second axis; PCA3, third axis; PCA4, fourth axis; AFR, anal fin rays; SLL, scales in the lateral line; SCP, scales in the caudal peduncle; SDLL, scales between dorsal fin and lateral line; SALL, scales between anal fin and lateral line.
