KOMPAS.com - Seperti jenis hewan pada umumnya, laba-laba serigala jantan yang masuk dalam keluarga Lycosidae menerapkan beberapa teknik rayuan untuk mencari perhatian betina yang akan dikawini. Laba-laba jantan melakukan gerakan-gerakan khas dan petunjuk visual di musim kawin saat bertemu laba-laba betina.
Laba-laba jantan mengetuk-ketukkan kaki atau menggerakan badan mereka untuk menciptakan getaran pada daun, batu, kayu, atau tanah. Sinyal rayuan yang dikirim oleh jantan, menurut penelitian University of Cincinnati, berubah tergantung pada lingkungan di sekitarnya.
Tujuan perubahan itu adalah untuk memaksimalkan rayuan untuk menarik teman kawin. Sinyal paling efektif ketika dikirimkan lewat daun. Jantan berhasil menarik perhatian betina 85 persen.
"Temuan ini menunjukkan kalau invertebrata punya kemampuan lebih untuk mengubah tingkah laku," kata Profesor Biologi George Uetz yang memimpin studi. "Mereka bisa mengimbangi perubahan lingkungan agar tetap berkomunikasi," tambahnya.
Tidak hanya menarik perhatian, rayuan itu juga diperkirakan kadang merupakan sinyal dari jantan agar betina tidak memakan mereka. Asal tahu saja, serigala laba-laba betina kadang-kadang bersifat kanibal begitu selesai kawin.(National Geographic Indonesia/Alex Pangestu)
