no they are not but some of them are
No.
the snake is only deadly to fish, but not to humans. it will take allot of bites to in pulse venom to interact to humans ( like one billion bites to be deadly) and is less than one percent deadly to humans.
Penguins are not considered deadly animals. They are cute and charismatic birds that mainly eat fish and other small marine creatures. While they may bite or peck if they feel threatened, they are not known to be aggressive towards humans.
Yes; they can be.
Yes. But not fatally to humans.
huskies are not Normally deadly to humans but can be deadly to other small animals such as squirrels, birds or rodents.
If provoked in such a way that they become aggressive towards you, definitely. A pet bull is far more deadly than a bull that has been raised on his mother because he tends to feel he needs to assert dominance over humans, not other cattle.
Skinks do bite but don't sting humans. I have been bitten by one, it can hert depending how much you can take and how long they bite. I've heard that they even bite if they like like you. I would watch out and make sure there are no diseases before going up close.
skinks have blue tails
Yes skinks have backbones which makes them a vertabrae.
Skinks eat other skinks. Big Skinks eat the skinks that are smaller then the bigger skinks. They drink milk from cows as well. There main thing they eat is snails. How skinks catch snails: They first jump on the snail and stomp ot it to make it crushed. (they prefer snails crushed)
