Kaloplocamus peludo

Kaloplocamus peludo is a sea slug, specifically a nudibranch and a shell-less marine gastropod mollusk belonging to the family Polyceridae.

The living animal is generally orange. Its entire back is covered with regularly spaced brown dots of similar size, except at the tips of the side appendages, which are pale yellow. An opaque white line runs irregularly from the front of the head to the rear of the back; this line splits around the gill leaves, encircles them, and then rejoins behind them. The rear tip of the foot is thin and pointed, colored yellow like the tips of the side appendages.

The body has two types of appendages. The first type is longer and wider, with three pairs positioned along the sides. These have branched tips, where each branch has a rounded base and a long, thin, sharp extension.

The entire length of these appendages is covered with small, sharp outgrowths. The second type is thin and long, with many small, sharp, simple branches. These appear on the sides, foot, back, and oral veil—15 to 17 per side, with six on the oral veil.

The rhinophores have a lamellate club and a stalk with small, thin, sharp branches. Each rhinophoral sheath edge has three branches: the middle one resembles the large side appendages, while the other two match the smaller body appendages. The oral tentacles are simple, cylindrical folds of the mantle. There are three tripinnate gill leaves, which bear long, simple, thin branches like the smaller appendages.

The type locality is Batangas, Luzon Island, Philippines. The original description also reports the species across a wide area of the Indo-Pacific, from the Philippines, Papua New Guinea, Palau, the Marshall Islands, and Japan to Tanzania. It has since been recorded from Heron Island, Australia.
