A seven-foot male bottlenose was found washed up on Fort Myers Beach, Florida on May 7 - the second dolphin found within a month on that beach having ingested human trash. Earlier a female dolphin calf was found on the same beach having ingested two plastic bags and a balloon fragment
The trash - a complete hose, including nozzle and metal radiator clamp - is believed to be part of a portable shower kit that allows travelers and campers to wash themselves.
The trash was discovered during necropsy examinations on the carcasses by the Florida Fish and Wildlife Conservation Commission's Fish and Wildlife Research Institute.
The institute urged people in a Facebook post to look closely at their trash disposal habits and participate in organised clean-ups.
'Your actions can make a difference - secure and properly dispose of trash, take part in coastal cleanups and share information on how to reduce marine debris with others,' the post reads.
It added that although the garbage is 'a significant finding... there are many additional factors to consider before a final cause of stranding and death for the dolphin can be determined.
'Samples collected during necropsy will be sent for analysis to help with this determination.'
