Beaks of all birds are used as tools to eat, build, and preen feathers. Beaks are made of keratin; as are their feathers and toenails.
Salmon sharks are primarily piscivorous, meaning they eat fish, but they have also been known to eat squid, shrimp, and crabs. I would not classify them as omnivores.

Spinosaurus was mainly piscivorous, as you probably know, but fish were certainly not the only food source for Spinosaurus. It was probably capable of taking down small-medium sized prey like the Iguanodont, Ouranosaurus. However, larger animals like Paralititan or Aegyptosaurus, were probably too large for Spinosaurus too take down. Even Carcharodontosaurus, which was specifically adapted for taking down large sauropods, would need help from several other members of the same species. When hunting other dinosaurs, Spinosaurus may have grappled the prey with it's huge arms then bit into the prey and thrashed it's head back and forth, using it's long neck.
A piscivorous animal is one that primarily feeds on fish. These animals have adapted to hunting and consuming fish as their main source of food in their diet. Examples of piscivorous animals include penguins, ospreys, and some species of fish.
Any fish-eating eagle could be simply known as a piscivorous eagle. This just means "fish eating eagle"
An animal that eats fish is called a piscivore. Some animals, like bears or alligators, only eat some fish, and are therefor partially piscivorous. Other animals live exclusively on fish, like seals, and are completely piscivorous.

Puffins are piscivorous (fish eating) birds. They catch and eat (and bring back to their nests for their young) any type of small fish. This would include herring.
Piscivorous mammals are mammals which primarily eat fish. They are not clearly defined by morphological features, but more often share similar tooth structure. These teeth are strongly recurved towards the back of the throat, to prevent fish from escaping. Some marine mammals have piscivorous teeth (such as the seal and some sea lions). Other marine mammals such as dolphins and porpoises have homodont teeth. These are comprised of many identical peg-like structures.
Synonyms: halieutic, ichthyic, ichthyoid, ichthyological, ichthyophagous, piscatorial, piscatory, piscine, piscivorous any of various cold-blooded, aquatic vertebrates, having gills, commonly fins, and typically an elongated body covered with scales.
Sheepshead fish are preyed upon by larger predators such as sharks, bottlenose dolphins, and larger predatory fish like groupers and barracudas. Additionally, humans also consume sheepshead fish as part of their diet.
Pteranodon lived on the coast of the Western Interior Seaway. The Western Interior Seaway was a subtropical, shallow sea that stretched from what is now the Gulf of Mexico to Hudson Bay, splitting North America in half. Pteranodon were piscivorous, or fish eating, and would have depended on the abundant waters of the shallow sea for food.

Spinosaurus lived in North Africa from Morocco to Egypt between 112 and 97 million years ago. The climate there was tropical, and the landscape was a coastal tidal plain with mangrove swamps. Spinosaurus was adapted for a piscivorous, or fish eating, lifestyle because of its long, narrow jaws filled with narrow, interlocking teeth.
Human trophic level varies. If the individual in question ate only moray eels (who are independently about a trophic level of 4, on account of being mostly piscivorous) then I imagine the human would be at a similar level. If the eel made up a part of an otherwise omnivorous diet, then I expect the person's trophic level to be closer to 2.5-3.0
