Specific reasons for the decline may include climate change, chytridiomycosis, or volcanic activity, but the main threat is habitat destruction as logging, agricultural activities, and human settlement reduce their often tiny, fragmented ranges. Survey work is being undertaken to assess the status of these salamanders, and to better understand ...
The rough-skinned newt Taricha granulosa of the Pacific Northwest produces more than enough tetrodotoxin to kill an adult human, and some Native Americans of the Pacific Northwest used the toxin to poison their enemies. [15] However, the toxins are only dangerous if ingested or otherwise enter the body; for example, through a wound.
The hellbender (Cryptobranchus alleganiensis), also known as the hellbender salamander, is a species of aquatic giant salamander endemic to the eastern and central United States. It is the largest salamander in North America. A member of the family Cryptobranchidae, the hellbender is the only extant member of the genus Cryptobranchus.
Non-commercial aviation is remarkably dangerous, with hundreds of accidents occurring each year. There were 1,248 accidents in 2009, 1,236, and in 2010, and 937 so far this year. In total, 1,112 ...
These amphibians usually sequester toxins from animals and plants on which they feed, commonly from poisonous insects or poisonous plants. Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, [1] [2] and two species of frogs with venom-tipped bone spurs on their skulls, amphibians are not known to actively inject venom.
Male marbled salamanders have also been shown to have a higher survivorship than females. [9] Marbled Salamanders in the northern portions of their range can also go into a state of torpor to survive the cold months. [10] Adults spend most of their time in their burrows or under logs, as is the case with most mole salamanders.
Some people are fearful of bugs (and arachnids), especially ones we have never encountered before. As the new Joro spider makes its way to New Jersey it is normal to be scared of the creature and ...
This salamander can be poisonous to its predators because of the excretion of a white poison through its glands when threatened. The northwestern salamander inhabits both forest and water bodies, but has a proclivity to live in burrows in the forest. The salamander also chooses to live under rocks, debris, and trees in the forest environment. [36]
