This is a mesopelagic species occurring mainly within the tropical
regions of the Atlantic, Pacific, and Indian Oceans and extending over
a wider geographical range (Fig. 10) than T . cristata or T . tricuspidata
(Figs. 10, 11). Atlantic: present in the west and in the east between
40"N and 40"s. Pacific: from about 36"N to about 38"s but not
present in the cooler water of the California Current nor in the Peru
Current. Indian : present between 1O"N and about 40"s. Adults below
700 m during the day; performs diurnal vertical migration. Attains a
length of 25 to 32 mm. (Ortmann, 1893; Hansen, 1905a, 1912, 1915,

Boden et ul., 1955 : 300-301, fig. 7. T. biproducta Ortmann, 1893 : 8, Taf. 1, fig. 1.
Occurs in tropical and subtropical waters of the Atlantic and
Pacific (Fig. 10). Atlantic: recorded from Sargasso Sea and near
Bermuda. Pacific: between 30"N and 35"s in warmer central water
masses. Indian: found east of Natal near 30"s 32"E. Has extensive
vertical distribution having been taken from about 500 m to below
1000 m depth.

Attains a length of about 40 to 55 mm.
