Spiders at the New York Hall of Science went on winter vacation to Florida, according to a sign posted at the museum. In fact, the spiders had died.

Certain fish wear “uniforms” to keep from being eaten, according to a new study published in Current Biology. Cleaner fish, which eat parasites off of larger fish, have a dark stripe and are colored blue and yellow. The larger fish recognize the colorful pattern and don’t eat the fish because of the service they perform. The researchers think that the cleaning fish developed their color patterns over time, as fish with those colors attracted more clients and got eaten less often.
