Fact Friday

Ctenophore floating thru the water column.

Modern ctenophores, or comb jellies, are soft-bodied, meaning they are 95% water and have no hard body parts.  Ctenophore fossils from the Cambrian period indicate that the ancient form of these creatures had a hard skeleton.  Scientists believe this skeleton was part of a trend to “armor up” during the Cambrian due to intense predation.
