Lamprey eels are parasitic and feed on the blood and tissues of other fish by attaching to them with their suction-cup mouths. In contrast, hagfish are scavengers that primarily feed on dead or dying fish, as they lack jaws and instead use their slime-producing capabilities to access the insides of carcasses. While both have unique feeding strategies, neither actively hunts healthy fish like many other predators do.
Hagfish and lampreys are apart of Agnatha which means jawless fish. Hagfish are a parasite fish but can be free swimming. Both jawless fish will feed on carcasses on the bottom of the seafloor.
Yes, a lamprey does not have a jaw. Instead, it has a circular mouth with sharp teeth that it uses to latch onto and feed on the blood of other fish.
Lampreys are not decomposers. They are consumers.
Most fish are not jawless. There is a small group of very primitive fish called Jawless fish (Agnatha). However, they make up a very small proportion (<1%) of the fish species on earth. Jawless fish are things like lamprey and hagfish. All other fish, like trout, salmon, tuna, sharks, rays, cichlids, goldfish, etc, etc, have jaws. See the related link for more information on the primitive jawless fish.
fish and plant
They feed off of other fish in the Great Lakes And anywhere else the sea lamprey is located.
Barracuda, Grouper and Giant Trevally feed on moray eels.
Pacific lamprey are not typically known to kill fish. They are parasitic feeders that attach themselves to other fish to feed on their bodily fluids. While this parasitic behavior may weaken the host fish, it is not common for the lamprey to directly kill the host fish.
Hagfish are jawless marine fish, and generally feed on dead animals.
Lampreys attach themselves to fish and feed off the blood of fish. The Lamprey has an indirect lifestyle lasting between five and nine years.
Electric eels primarily feed on fish, but they also consume other small aquatic animals like shrimp and crabs. They use their powerful electrical discharge to stun or kill their prey before consuming it.
Yes, there have been rare reports of lamprey attacking humans, but such incidents are extremely uncommon. Lampreys are typically not aggressive towards humans and are more likely to feed on fish and other aquatic animals.
