Tick paralysis of a snake caused by Amblyomma rotundatum (Acari: Ixodidae).

A lethargic southern black racer, Coluber constrictor priapus Dunn and Wood, wild-caught in the Florida Keys, Monroe County, FL, was found to be paralyzed by the bite of a female ixodid tick, Amblyomma rotundatum Koch (Acari: Ixodidae). Removal of the tick restored the snake to normalcy within 18 h. Other, earlier reported cases of tick toxicosis in reptiles are reviewed and clarified.

At-sea measurements of sound penetration into sediments using a buried vertical synthetic array.

Acoustic bottom penetration experiments were carried out in a medium-grain sandy bottom at a site in St. Andrews Bay, Florida. These investigations used a new buried, vertical, one-dimensional synthetic array system where a small hydrophone was water-jetted into the sediment to a depth of approximately 2 m.
