Scientists, naturalists and volunteers identified 433 species on Sandy Hook during the first-ever BioBlitz there last month, according to the American Littoral Society.

The Sept. 16-17 BioBlitz provided a 24-hour snapshot of the diverse life on and in the waters around Sandy Hook, according to the society, a hook-based coastal conservation group that helped organize the event.

A BioBlitz is a competition, educational event and scientific endeavor, according to the society.
