OK, I'm perplexed... are you sure the 223X is correct ?!
All of my calculations are coming out way lower than that.

Siluridae (122x difference):
Silurus glanis (max 5 m)
Silurichthys sanguineus (max 4.1 cm)

Characidae: (103.7x)
Hydrocyanus goliath (1.4 m)
Xenurobrycon pteropus (1.35cm)

Serranidae (83.3x):
Epinepheleus itajara (2.5 m)
Plectranthias lomgimanus (3 cm)

Dalatiidae: (26.7x)
Eridacnis radcliffei (max 25 cm)
Somniosus microcephalus (max 6.4 m)

or the Acipenseridae (22.2x):
Huso huso (max 6 m)
Pseudoscaphirhynchus hermanni (max 27 cm)
