Are fish fins sharp?
Many fish species evolved parts of their fins into sharp, spiny, needle-like elements — called fin spines — that function to protect the fish against predators. Such spines have evolved independently in different lineages and are considered evolutionary drivers of fish diversity.
How do you not get finned by a fish?
Holding the fish near the head helps avoid the dorsal, tail, pectoral, pelvic and anal fins. Remove the hook by grabbing the eyelet or small hole that’s connected to the line. Pull the hook back out in the same direction it went in. You can also use needle-nose pliers or a hook remover to flatten the barb.

Do fishes feel pain?

Hook wounds may appear minor to anglers, but damage to the gills, eyes, or internal organs can be fatal.

Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Can you hold all fish by the mouth?
Fish with teeth shouldn’t be lipped at all (duh), but you can still support their belly with one hand and their tail with another. Holding fish by gill covers should be avoided as this can damage their gills. Many also fish have sharp gill covers, like snook, and can badly cut your hand if you hold them like that.
What happens if you touch a fish?

Can I hold my fish?
If the fish is big enough that it can be held with 2 hands, it’s best to do so. This will keep the weight of the fish from damaging its bones or internal organs. Holding a large fish with 1 hand can put dangerous amounts of pressure on its jaw or gill plate.
