Jessica Farrer, investigation head pinch The Whale Museum connected Washington's San Juan Island, was among a squad of scientists who responded to nan sighting of nan whale successful precocious July.
The whale was initially spotted successful nan Salish Sea, nan inland waters betwixt Washington and British Columbia.
But since then, location hasn't been different sighting, Farrer said.
'Everybody has an emotion erstwhile they witnesser a humpback whale dive, and you spot those monolithic flukes that are complete 15 feet across, and here's this whale, it's conscionable mislaid that. It's for illustration america losing our legs,' Farrer said.
Farrer, on pinch nan galore experts that person reviewed nan photos of nan whale, work together that it mislaid its flukes owed to entanglement.
The humpback could person gotten stuck successful mooring lines, pots aliases nets, according to NOAA Fisheries.

'There are truthful galore entanglement hazards floating astir nan world's oceans. Old sportfishing cogwheel that has surgery free from sportfishing vessels aliases nan cogwheel that they time off behind,' Farrer said.
'And these whales person to aquatics done that and humpback whales are astatine an accrued consequence because they person those very agelong pectoral flippers.'
Farrer's main interest for nan tailless whale is that it won't beryllium capable to aquatics accelerated capable to drawback up pinch smaller food truthful that it tin provender itself.
Statistics from NOAA Fisheries show location were 16 confirmed humpback entanglements disconnected nan coasts of Washington, Oregon and California past year.
The twelvemonth 2016 was a peculiarly bad 1 for humpback entanglements, topping a full of 40.
This was apt owed to the Dungeness crab sportfishing play successful California that year, which could person meant a batch much sportfishing cogwheel for whales to effort to navigate through, AP reported.
California has since changed nan measurement it regulates commercial Dungeness crab fisheries successful an effort to protect animals from entanglement.
Justin Viezbicke, a whale entanglement responder pinch NOAA Fisheries, said location are sightings of whales on nan westbound seashore without flukes astir each twelvemonth aliases two.

Farrer hopes nan shocking images of this severely injured humpback will beryllium a wakeup telephone and lead to moreover much stringent protection efforts.
'It's 1 point to show pictures of whales that are entangled aliases to talk astir whales that person died from entanglements aliases spot entanglement scars, but this whale swimming successful nan Salish oversea wholly without a tail is nan poster kid for nan hazards that they're facing.'
