Big fish show a marked preference for sheltering under large, flat table corals, as opposed to branching corals or massive corals, Australian scientists have found.

Australia’s sea snakes may be more in danger of extinction than previously thought, marine scientists say.

Researc­hers have long thought of males as the lone dancers in courtship display, leaving females to judge, but in one species of cichlid fish, the opposite occurs, according to new research.

A new study has found that it is more important for marine life how that prey is distributed rather than the abundance of prey.
