tomorrow marks the fifth anniversary of the spill and while the gulf is on the rebound there are still questions about the impact on animals who call it home. more now from our chief environmental affairs correspondent, anne thompson who joins us from venice harbor in louisiana. anne good evening. >> reporter: good evening, carl. commercial and recreational fishing are slowly coming back but five years after the spill, these waters still hold secrets scientists are . bottlenose dolphins the grace fellaini denizens of the gulf and one of the enduring mystery of the spill. as they have every spring since the spring noah and a team of scientists are counting them in louisiana's bay. >> we've seen animals today, both of which we expected to have a calf with them and we haven't seen a calf so those are reproductive failures. >> reporter: far more stranded turning up

dead or distraught. maybe a year but this one has lasted five years. the longest stranding event in the gulf of mexico in recorded 1,068 dolphins stranded since the deepwater horizon blew up 95% dead. in 2011 alone the deaths were five times higher than the annual average. how much faster are dolphins dying in beritera bay than in the gulf. >> the highest in the area impacted by the spill. >> reporter: a year r the spill we were with her and her team as they examined the surviving dolphins finding lung disease and adrenal issues. >> they're certainly consistent with the facts you would see after exposure to oil and we've looked at other potential causes and we've ruled these out. >> reporter: such as a virus and toxins two rshs bp points to as possible causes. there are other wildlife mysteries.

the oil temporarily tainted the waters where the endangered turtles swim and eat. some wonder if that's why nesting numbers in texas that were growing before the spill are now plummeting. >> when that trajectory changed and the kleins in 2013 and 2014 it was very disappointing. >> reporter: bp suggests record cold temperatures may be to blame but shaver says that would not impact adult turtles and the issue of coastal erosion. pelicans struggled on cat island and measured more than four acres. today it is a sandbar. the oil hastened the erosion but bp points to a study showing erosion rates returned to normal 18 months after the spill. now federal officials are telling of all the damage done to the marshes and the wildlife and they'll hand bp a bill called the natural resources damage assessment. that will come on top of $4 billion in

criminal penalties and up to $14 billion in civil fines that have yet to be assessed. carl. >> anne thompson along the louisiana coast. anne thanks a lot. >> when we come back ringo star gets a big honor with a little help from his friends. in small business you have to work hard, know your numbers, and stay focused. i was determined to create new york city's first self-serve frozen yogurt franchise. and now you have 42 locations. the more i put into my business the more i get out of it. like 5x your rewards when you make select business purchases with your ink plus card from chase. and with ink, i choose how to redeem my points for things like cash or travel. how's the fro-yo? just peachy...literally. ink from chase. so you can. people with type 2 diabetes come from all walks of life. if you have high blood sugar ask your doctor about farxiga. it's a different kind of medicine that works
