Urocaridella is a small genus of shrimps with currently seven species although many researchers claim that there are many more left to be discovered and described. Some of these tiny mosquito-like shrimps clean the mouths and bodies of moray eels and various other cave dwelling fish that share its habitat. Unlike Lysmata and Periclemenes, Urocaridella are capable of prolonged hovering and free swimming, and prefer doing so than perching (Tyk, 2013; Steinke, 2015; Khalaf, January 2018).

One of the neatest things about Urocaridella is their comical way of swimming. When swimming or hovering, they hold their claws downward and buzz around in an almost mosquito-meets-hovercraft fashion (Tyk, 2013; Steinke, 2015; Khalaf, January 2018).

They commonly swim by vigorously beating their pleopods when moving towards their fish clients. This behaviour gives them the strange appearance of hovering in midwater (Calado, 2008; Khalaf, January 2018). Sometimes they are called the Helicopter Shrimps (Khalaf, January 2018).

Urocaridella renatekhalafae is a species of cave clear cleaner shrimp in the family Palaemonidae. It was identified as a species new to science in 2018, and was named in honour of the discoverer's mother, Renate Khalaf (Wikipedia, 2018).

Description and Distinctive Features Urocaridella renatekhalafae grows up to 3cm in length. The body is transparent with white and red dots on the cephalothorax and abdomen. The inner organs can be seen clearly.

The eyes are normally stalked. Legs are slim and long with white and red bands and rings. The red antennas and antennules are long. The very long rostrum is white in colour. Telson and uropod are transparent with white and red rings and dots (Wikipedia, 2018).

Urocaridella renatekhalafae Khalaf, 2018 reach a length of 3.00 cm. The large adult female is almost transparent with white and red dots on the cephalothorax and abdomen. The legs have red and white rings and bands. The first and second pair of legs (pereopods) Gazelle : The Palestinian Biological Bulletin – Number 169 – January 2019

has white and red small claws, the first pair being smaller than the second pair. Small individuals are less pigmented than large ones, and the overall colour is probably less noticeable at night than during the day. The internal parts and organs like the cephalothorax, stomach, digestive gland and ovary are often observed due to transparency; the ovary has an orange or light green color depending on the development of vitellogenesis (Khalaf, January 2018).

The cephalothorax has a very long white coloured rostrum bent upwards and largely exceeds the antennal scales. The eyes are normally stalked. The antennas and antennules are long and red, with some white dots at the base (Khalaf, January 2018).

Pereopods (walking legs) are long and slender. The pleopods (swimming feet under the abdomen) are effective and allow the animal to remain immobile in open water. When swimming, only the pleopods are in action, the pereopods hang under the animal (Khalaf, January 2018).

The abdomen forms a characteristic right angle at the level of which is a red spot preceded by a white spot. The red spot may widen to form a band that runs laterally through the abdomen. At the base of the telson, there is red and white bands; followed by red and white dots and rings on the uropod (Khalaf, January 2018).

Size Urocaridella renatekhalafae grows to about 3.00 cm long (Khalaf, January 2018).

Diet Renate Khalaf‟s cleaner shrimp feeds on parasites living on fish and moray eels, mouth mucous, copepods and food leftovers. It attracts its host by laterally vibrating its red antennas and antennules; and when the fish is ready, it approaches the shrimp, which begins its cleaning service in the so called “cleaning stations” (Wikipedia, 2018). It sometimes enters the fish‟s mouth and gill cavities (Khalaf, January 2018).

Habitat It lives in small crevices and caves in rocky and coral reefs to a depth of 25 meters (Wikipedia, 2018).

Biology Transparent colouration in Urocaridella renatekhalafae is seen as a first line defence against predation. In its natural environment, the Renate Khalaf‟s Cave Clear Cleaner Shrimp lives in groups in small caves and crevices on the reef in locations called "cleaning stations”. It attracts its host by a lateral vibratory movement of its red antennas and antennules. When the fish is set, it lands on the bottom near the shrimp.

Then, the shrimp swims towards the fish and begins the cleaning. It sometimes enters the fish‟s mouth and gill cavities (Khalaf, January 2018).

These shrimps are regularly observed in the company of the moray eels and fish which they clean. They can change host easily, including a diver, while swimming in open water (Khalaf, January 2018).

The biology of this unusual shrimp does not appear to have been researched by scientists. This shrimp forms groups of a few individuals in small caves or in the immediate vicinity; they have their cleaning station there and constitute a “guild” (solidarity association) (Khalaf, January 2018).

Reproduction The eggs are fixed on the pleopods. As this shrimp occurs in warm waters in its distribution range, it is likely to reproduce all year round (Khalaf, January 2018).

Distribution Urocaridella renatekhalafae was described and scientifically named from the Fujairah and Khorfakkan Sea, East Coast of the United Arab Emirates, Gulf of Oman, Arabian Sea. It is distributed in the Red Sea, through the Indian Ocean and the Western Pacific Ocean (Wikipedia, 2018; Khalaf, January 2018).

Etymology / Derivation of the Scientific Name The genus name Urocaridella derives from Greek Oura meaning tail, and Latin Carid meaning marine crustacean; and the species name renatekhalafae is Latin for “Renate Khalaf” (Mother of the Taxonomist, born in 1941) (Khalaf, January 2018).

This new Cave Clear Cleaner Shrimp species was classified and named by the Palestinian-German Zoologist Prof. Dr. Sc. Norman Ali Bassam Khalaf-von Jaffa in January 2018, and the specific name „renatekhalafae‟ was named in honor of his beloved mother “Renate Margarete Khalaf geb. Weber” (born in Saarbrücken, Germany in 1941) (Khalaf, January 2018).
