The first approved modified live fish vaccine has been developed by Agricultural Research Service scientists. This new vaccine, which is a live organism rendered unable to cause disease, will help the catfish industry solve a key problem and will give producers a more cost-effective way to raise healthy fish for consumers. The vaccine can be used in fish as young as seven days and up to 31 days after hatching. With their silky black fur and pretty white stripes, skunks might seem a lot like an oversized kitty cat. But a whiff of their distinctive spray will make anyone lose the desire to cuddle up with one.
Skunks produce the spray in glands on both sides of their tails.
When another animal, such as a dog, threatens a skunk by barking or cornering it, the skunk will immediately start showing warning signs of stomping its feet and flicking its tail. If Fido doesn't get the message to back off, the skunk will turn around and eject its yellow, stinky spray. Some skunks can spray as far as 12 feet. The spray, made up of sulfur, hydrogen and carbon atoms, creates a bad smell. It will cause temporary blindness and make Fido's skin burn and itch for a little while - giving the skunk a chance to make a quick getaway.
