Fish

A diver filmed a pair of young ocean sunfish off Canada's coast and experts estimated them to measure 24 inches across — five times smaller than the size they reach as adults.

Researchers recorded the movements of ocean predators and found many diving to depths of over 3,200 feet for reasons that are currently unclear.

MBARI researchers came across a rarely seen dreamer anglerfish off California's coast. Video footage of the alien-looking fish only shows its silhouette because its skin is so dark it absorbs almost all of the light that hits it.

An epaulette shark pup born in August at Brookfield Zoo hatched from an egg that was not fertilized by a male shark. It's the second time this species has undergone a virgin birth in captivity.

Astonishing footage from Planet Earth III, which premieres Nov. 4 on BBC America and AMC+, shows a herd of seals fending off an attack by the world's most notorious predator off the southern coast of Africa.

A deep-sea Pacific footballfish found on Moro Beach in Crystal Cove State Park is the second of this species to wash up in recent years, but the reason behind the strandings remains a mystery.

Scientists have performed a necropsy on a great white shark that washed up in Nova Scotia — the fifth unexplained stranding of its kind in a year — but were unable to determine the cause of death.

Orcas have been feasting on sharks' livers off the coast of South Africa for several years and could now be doing the same in Australia, the carcass of a great white suggests.

Fish smell is from degrading lipids and bacterial reactions that increase in potency over time.

In the 1990s, a group of juvenile bull sharks were left stranded in a golf course pond in Australia, where they thrived for decades. Now scientists are trying to understand why.
