- Seals and sea lions are mostly fish-eaters, although most of the species also eat squid, mollusks, crustaceans, marine worms, sea birds, and other seals. The ones that eat mostly fish specialize in oil-bearing species like eels, herrings, and anchovies because they swim in shoals and are easy to catch, and are good energy sources.

Sea lions are carnivores, which means they only eat meat. They feed on a variety of marine animals, including fish, squid, octopus, clams, and other shellfish. Their diet varies depending on their location and the availability of prey.
Seal vs. Sea Lion: Diet and Hunting Prey. Seals and sea lions have diverse diets, but there are some general trends in what they prefer to eat. Seals typically feed on fish, squid, and crustaceans. Some larger seal species, like the leopard seal, also feed on other seals or penguins. Sea lions, on the other hand, primarily eat fish and squid.

California sea lions are predators that obtain all their food from the sea. They feed on more than 50 species of fishes and cephalopods, feeding primarily on squids, octopuses, hake, northern anchovy, opaleye, and herring. They are opportunistic predators of salmon, lamprey, and some bottom-dwelling fishes. California sea lions on the Washington co...
A Galápagos sea lion may spend an average of 15.7 hours foraging at sea. A foraging trip may entail 85 to 198 dives. A sea lion may use its sensitive vibrissae to explore and locate food. California sea lions don't chew their food. They swallow it whole or tear it into chunks.
California sea lions generally obtain the water they need from their food. Most research indicates that California sea lions don't drink water, though males have been observed apparently drinking seawater while fasting.
During the breeding season, adult males fast when defending their territories. Leaving their territories to feed would necessitate re-establishing territorial boundaries and would result in lost mating opportunities. This fasting usually lasts a few weeks.
Scientists have found stones in the stomachs of various species of sea lions, including California sea lions. One specimen was found to have 27.2 kg (60 lb.) of stones in its stomach. Experts don't know why sea lions swallow stones. Some theories include the following: adding extra weight for ballast while swimming, helping to stop irritation from ...
Seals and sea lions are both carnivorous, feeding on a variety of marine life. However, their hunting techniques and prey preferences differ. Seals are efficient swimmers and can dive deeper and for longer periods. They primarily feed on fish, squid, and crustaceans, using their whiskers to detect prey in murky waters.
Sea lions are predators. They consume large amounts of fish and help to regulate prey species populations. They are also prey, however, and serve as an important food source for large animals like great white sharks, hammerhead sharks, blue sharks, and killer whales.
Nov 23, 2021 · What eats a sea lion? Sea lions are in the same taxonomic group as walruses and seals, known as pinnipeds. Aquatic predators target seals and sea lions as they are high in fat content and relatively easy to catch. Walruses are much heavier than other pinnipeds and have large tusks they protect themselves with, thus they are predated on much less.
In their captivity, they have a diet based on fish, where the presence of capelin, mackerel, herring, and pompano stands out. This fish-based diet is supplemented by squid, which is almost always given sporadically as rewards when the sea lions perform tricks.
