Why in news
CMFRI researchers documented the first evidence of both heterosexual and homosexual mating behavior in the Indian squid (Uroteuthis duvaucelii) in the Arabian Sea.
Background
The study analyzed 232 female squids from the Arabian Sea off Kochi. Researchers identified active mating throughout the year with peak activity in October and found spermatangia on a male squid, indicating same-sex sexual behavior.
