Behavior
Judging by strandings, the whales occur in small groups. They probably feed on squid.
A sighting made in 1998, west of the island of Tenerife, involved three whales swimming over waters 1500 meters deep. Another small group was seen south of the island of Gran Canaria. Although timid, the whales allowed close photos. They surfaced for a short time, and their dives lasted for around an hour.
In September 2008, northeast of the island of Lanzarote, some Gervais' beaked whales were photographed breaching out of the water.
On May 5, 2011, one juvenile female specimen was found dead and beached at Playa Larga of Maunabo on the southeast corner of Puerto Rico (Caribbean Sea). The juvenile had her stomach filled with (10 pounds) of plastic bags. On July 10 of the same year, one specimen was found dead in the Yucatán Peninsula, México, further investigation is being performed to confirm the species in this case.

Famous quotes containing the word behavior:
“If you are willing to inconvenience yourself in the name of discipline, the battle is half over. Leave Grandma’s early if the children are acting impossible. Depart the ballpark in the sixth inning if you’ve warned the kids and their behavior is still poor. If we do something like this once, our kids will remember it for a long time.”
—Fred G. Gosman (20th century)
“Fatalism, whose solving word in all crises of behavior is “All striving is vain,” will never reign supreme, for the impulse to take life strivingly is indestructible in the race. Moral creeds which speak to that impulse will be widely successful in spite of inconsistency, vagueness, and shadowy determination of expectancy. Man needs a rule for his will, and will invent one if one be not given him.”
—William James (1842–1910)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
