Abstract / Introduction / Summary:
A single female specimen of the Horrid elbow crab Daldorfia horrida (Linnaeus, 1758) (carapace width 72.7 mm) was collected using a lobster gill net at a depth of 15 m from off Nakagi, Minami-Izu Town, Izu Peninsula, Shizuoka Prefecture, Japan. This species is widely distributed in Indo-West Pacific, but the northernmost location at which it had previously been recorded was from Kihoku Town, Mie Prefecture. This specimen is the first record of D. horrida in Shizuoka Prefecture, which extends the species known northern distribution limit. The crab’s presence suggests that juveniles were transported along the Izu Peninsula coast and established themselves due to the prolonged Kuroshio Current meander, which is expected to last until April 2025.
