What are Cnidae? Specialized capsules unique to members of the phylum Cnidaria Many purposes Defense Attachment Immobilization of prey Single-use
What are Cnidae? Abundant!
What are Cnidae?
(Scale Bar = 0.1mm)
Variability from species to species Good candidate for aiding classification
Capsule Type Capsule Length Capsule Width Relative Abundance Location Obtained
Data collected from the literature is integrated into tables linked to the larger database
Future Functions Combine data from multiple sources Use statistics to identify species- specific tendencies Display images from original literature
