A recent paper showed that salt water is not a deterrent to the spread of Burmese pythons. Does this mean that this snake could already be invading other parts of Florida farther away from the Everglades?
A number of Burmese pythons have been found on Key Largo, and a few in the Lower Keys. However, there is as yet no evidence of a breeding population anywhere in the Keys. Because pythons regularly escape or are released from captivity, it can be diff
Cicadas are not harmful to humans and they rarely cause significant plant damage.
No, salmon are not endangered worldwide. For example, most populations in Alaska are healthy. Some populations in the Pacific Northwest are much healthier than others.
No. Although sturgeon and catfish can be found in the same habitats and they both have barbels (whiskerlike growths extending from the jaw), they are not closely related. Sturgeon are much more primitive than catfish.
In some places, yes, but under several constraints. Specifically, importation of live snakeheads and their interstate transport is prohibited. Many states prohibit possession of snakeheads, and several of those states have done so for decades.
Experimentally, it was found that this may be possible.
Most snakeheads will avoid contact with humans. In captivity, many will actually act shy around people. However, when guarding their eggs or young, they can become aggressive if approached.
Dead snakeheads--on ice or frozen--can be imported for food purposes to any state except those where importation or possession of dead snakeheads is illegal.
