The anemone shrimp Periclimenes rathbunae Schmitt, 1924 (family Palaemonidae), is a
common associate of shallow-water anthozoans in the tropical western Atlantic. It has been
reported from several sea anemone species, an octocoral, a corallimorpharian, and a
scleractinian coral (Brinkmann and Fransen 2016).During a coral reef survey in Curaçao (1
April 2014), a previously unknown association was found between an individual of P.
rathbunae and a lettuce slug, Elysia crispata Mörch, 1863 (Fig. 1). It occurred on the reef …
The anemone shrimp Periclimenes rathbunae Schmitt, 1924 (family Palaemonidae), is a common associate of shallow-water anthozoans in the tropical western Atlantic. It has been reported from several sea anemone species, an octocoral, a corallimorpharian, and a scleractinian coral (Brinkmann and Fransen 2016).
During a coral reef survey in Curaçao (1 April 2014), a previously unknown association was found between an individual of P. rathbunae and a lettuce slug, Elysia crispata Mörch, 1863 (Fig. 1). It occurred on the reef slope (6–8 m deep) of Playa Kalki on the island’s northwestern tip (12 22′ 30 ″N, 69 09′ 28 ″W), where this slug appeared to be abundant (ca. 40 observed individuals per 1-h dive). The shrimp’s blue coloration matched that of its host, but it is usually dark red-brown (see, eg, Brinkmann and Fransen 2016; Horká et al. 2016).
