In this paper, 47 specimens of dragonflies and damselflies collected by H. Lindberg and his assistant S. Panelius in the Cape Verde Islands in 1953-1954 and identified by K.J. Valle and K.F. Buchholz, are presented. The damselfly Agriocnemis exilis Selys, 1872, collected in Boa Vista Island in February 1954, is added to the list of Odonata known from the archipelago. The collection also includes specimens from another damselfly, Ischnura senegalensis (Rambur, 1842), which was previously recorded in Cape Verde on only two occasions, in 1898 and 2000.
On 15 May 2013, on the beach near Calheta de Baixo, Maio Island, Cape Verde Islands (15º13ʹ20ʺN, 23º13ʹ12ʺW), the remains of a stranded cetacean were found. The animal had been butchered by local inhabitants and most of the flesh and blubber, as well as the intestines, had been removed, while the tail fluke had been chopped off. However, with the skull still present, it was immediately clear that it concerned a beaked whale Mesoplodon sp. The single pair of teeth (one of which was broken) placed back from the apex in the lower jaw allowed the animal to be identified as a male Gervais' beaked whale M. europaeus (Gervais, 1855).
Arthropoda is the most diverse phylum of the animal kingdom. The majority of bloodsucking arthropods of public health concern are found in two classes, Arachnida and Insecta. Mosquitoes, ticks, cattle flies, horseflies and biting midges are the main hematophagous groups occurring in the Cape Verde Islands and whose role in infectious disease transmission has been established. In this literature review, the main morphological and biological characters and their role in the cycle of disease transmission are summarized.
On 12 July 2013, an adult female loggerhead sea turtle Caretta caretta with an almost complete longitudinal carapace fracture was observed nesting and returning to sea at João Barrosa beach, Boa Vista, Cape Verde Islands. Due to the evident fracture instability and the likelihood of subsequent system infection development, an intervention was planned to prevent further health decline and eventual death. Beach surveillance was increased to raise recapture possibilities, based on the most likely nesting days for this individual. After 53 days, the animal hauled out again and was allowed to lay eggs before taken away for wound cleaning, stabilization, medication administration and surgery. An orthopaedic surgical intervention for shell repair was performed under field injectable general anaesthesia. The fracture was stabilised in six places by means of four marine resistant stainless steel plates and two orthopaedic wires screwed to the carapace. Finally, all implanted material was covered and protected with epoxy resin to maintain a smooth carapace surface and prevent potential entanglement.
