Oceanic Heat Wave
Tropical fish from off northeastern Australia have been spotted around parts of New Zealand, lured across the Tasman Sea by a record-breaking hot summer season.
The country’s unusual warmth was largely generated by what meteorologists term a “marine heat wave,” which has seen water temperatures nearly 10 degrees Fahrenheit above normal.
The rare appearance of the Queensland groper, also known as the giant grouper, has startled New Zealand divers, who fear the fish won’t survive once temperatures cool to near normal.
Happy Captives?
A controversial study suggests captive dolphins can be as “happy” as those swimming free in the wild, and also appear to look forward to human interaction.
French researchers played specific sounds before offering the dolphins different things to do, such as playing with new toys, interacting with a human or being left to do as they pleased. The marine mammals would clearly bob their heads out of the water when they anticipated a human was coming.
The scientists conclude this means the dolphins become excited when offered the chance to connect with their human trainers.
