Why is its neck so long?
For catching fish! (or other prey items)
There’s a whole group of turtles that fold their necks into their shells sideways rather than pulling them straight back (called sidenecks). Several of them have very long necks that they can fold back into their shell and then shoot out to grab passing prey. Snakeneck turtles have truly impressive neck reaches.
“Don’t mind me, Mr. Fish, I just have a short little neck I definitely couldn’t reach all the way over…”
“JUST KIDDING YES I CAN”
They have such cute creepy little faces. If they didn’t all get so big I would love to have one (puts another turtle on my Someday list).
The other trouble is that snakenecks can sometimes be a bit nippy and since their necks are long enough to reach all the way to the back of their shell NOWHERE IS SAFE.
