This teenager washed up on the beach

With so many nests and cute pictures of hatchlings, why are they on the threatened species list?

1.  Dead hatchlings
Excavated this nest and found 106 hatched eggs (white piles) and 88 dead hatchlings (dark piles).  Eggs get damaged by ghost crabs and roots.  Hatchlings are killed by ghost crabs, fire ants, getting caught in roots and drowning (still emerging and getting caught in nest during high tides or heavy rains).  All this and they have not even started towards the ocean - where they are prey for birds and fish.

2.  Strandings
This poor fellow washed ashore - his weight was estimated at approx 150 lbs.  It was bloated and all but 3 scutes (thin scale like coverings on shell) missing.  Because it was a juvenile, sex could not be determined.  There are numerous causes for strandings - getting caught in commercial fish/shrimp nets, fish hooks, predator bites, ingesting plastic (they eat jellyfish and plastic floating in water resemble food to turtles), and trash in general - are a few causes of death.
