It’s not just great white sharks hunting for Cape Cod seals these days.

Those on a whale watch learned that recently when they spotted a mako shark chomping on a seal, as they saw the water turn bloody.

Passengers on Hyannis Whale Watcher Cruises got a front-row seat to the mako shark feasting on a seal over the weekend.

“Yesterday is a day that everyone aboard will be talking about for a long, long time,” the local whale watch posted. “The whale sightings were spectacular… The talk of the day, however, will be the predation that we observed as a mako shark attacked and attempted to feed on a gray seal.

“While difficult to witness, it was a once-in-a-lifetime opportunity to see the true power of one of the ocean’s top predators,” Hyannis Whale Watcher Cruises added.

A recreational boater then approached the scene, which reportedly scared the mako shark away.

“I point this out as a reminder that all wild animals need, and deserve, their space, and hope that this anecdote serves as an example for how we humans can make better choices regarding our impact on wildlife,” the whale watch posted.

Much of the attention has been on white sharks along the Cape in recent years, as they search for seals close to shore.

The white sharks coming near public beaches continues to lead to many shark alerts, like on Tuesday along the Outer Cape.

“Two sharks spotted by spotter pilot off of Coast Guard Beach (Eastham) close to shore,” reads the shark alert on the Atlantic White Shark Conservancy’s Sharktivity app.

“White sharks spotted north of Nauset Light Beach, 50 yards offshore heading north,” reads another shark alert.

Cape shark alerts are issued when a great white shark sighting is confirmed close to a public beach. A notification goes out with each alert.

Meanwhile, there has been an increase in ocean sunfish being reported as great white sharks.

Although they look nothing alike, the sunfish’s large dorsal fin causes the confusion. Unlike sharks, they use their fin like a paddle, moving it back and forth to swim.

“Sunfish can also breach which results in a large splash which leads people to believe they’re a shark,” shark researcher John Chisholm posted. “If you do see a fin you can’t identify, always err on the side of caution! Exit the water and notify lifeguards/local authorities. You can also report on the Sharktivity app.”
