Lithophaga nigra (d’Orbigny, 1853) is an uncommon boring bivalve that inhabits dead coral skeletons and occurs in the Caribbean Sea and the Indopacific region. One specimen of this species was collected within a dead head of the coral Montastraea sp. in Playa Blanca, (bahía de Gaira) near Santa Marta at 10 m of depth, and it is recorded for the first time in the Colombian Caribbean.

Three species of the genus Heterodinium Kofoid are reported for the first time in coastal waters of the Colombian Caribbean. The identified species are Heterodinium rigdenae Kofoid, 1906, Heterodinium agassizii Kofoid, 1907 and Heterodinium angulatum Kofoid y Michener, 1911. Information about distribution of these species in the Caribbean Sea and the Gulf of Mexico is given.

The bivalve Corbicula fluminea Müller is recorded for the first time in Colombia, in the National Park Isla de Salamanca. This protected area includes freshwater channels and mixohaline lagoons influenced by waters of both the Magdalena River and the Caribbean Sea. This exotic bivalve occurs locally in freshwater channels close to the Magdalena River as well as in the latter, whereas another corbiculid native species, Polymesoda solida, is commonly found in the mixohaline lagoons. Densities of C. fluminea ranged from 10 to 100 ind/m2 along with low numbers of P. solida. Lengths ranged form 10 to 43 mm in a predominant muddy substrate. Local fishermen have stated that C. fluminea was established approximately in 1992; this clam is being artisanally exploited for human consumption along with P. solida, although fishery is mainly focused on the latter, due to its larger size.

We report the occurrence of the sponge-dwelling snapping shrimpSynalpheus dardeaui(Decapoda: Alpheidae) for the first time from Porto Seguro (Bahia, Brazil) and record an additional sponge host for the species,Irciniacf.strobilina. Synalpheus dardeauiwas previously known from Florida and some localities in the Caribbean Sea. Therefore, the present finding represents the first record of the species in the south-western Atlantic, extending its southern distribution limit by a latitude of 28° from Curaçao (12°N) to Porto Seguro (16°S). Variations between the Brazilian and Florida–Caribbean materials are discussed and illustrated.

Porites colonensis is a coral from the Caribbean Sea; colonies are foliaceous, undulated, and plate-like. Polyps are dark brown or red with small bright white or green centers; pali are present in corallites and the septal plan is bisymmetrical, conformed by three fused ventral septa, a dorsal solitary septum, and two pairs of lateral septa at each side of the dorso-ventral axis. P. colonensis is similar and can be confused with the smooth varieties of Porites astreoides and Porites branneri. There are three specimens collected from Colombia and previously identified as P. colonensis: one from Golfo de Urabá (Darién ecoregion), other from Islas del Rosario (Coralline Archipelagos ecoregion), and another from an unspecified locality, in addition to one published observation from the Golfo de Urabá without collected specimens. A recent finding of other specimens in the Tayrona National Natural Park (TNNP, Tayrona ecoregion) and the absence of a rigorous taxonomic revision for all specimens collected from Colombia showed that it was necessary to review the presence and distribution of P. colonensis in the Colombian Caribbean. A taxonomic review was done for all specimens collected from Colombia and previously identified as P. colonensis. Then, the morphologic variability of specimens that were confirmed as P. colonensis was described. Only the specimens from TNNP agreed with the holotype description of P. colonensis, while others agreed with flat varieties of P. astreoides. Thus, the presence of P. colonensis is confirmed for the first time for Colombia, but its presence in other Colombian localities outside Tayrona ecoregion could not be demonstrated. This is the only confirmed record of this species for the South American continental shelf. Furthermore, the skeletal characteristics of Colombian P. colonensis corallites showed large variability, exceeding the ranges previously described for the species.

Mass Stranding

The pygmy killer whale (Feresa attenuata) is an offshore, tropical and subtropical delphinid found in the Atlantic, Indian and Pacific Oceans. The species has only recently been studied, mostly from specimens collected from strandings. While over 52 reports exist for the Atlantic Ocean, only one record exists for the Caribbean Sea. A new record of a mass stranding of pygmy killer whales from the British Virgin Islands is documented and the pathology and life history of the specimens is described, associating the stranding process with the meteorological and oceanographic disturbance of Hurricane Marilyn, which devastated the Virgin Islands a day prior to the stranding. This stranding event constitutes the sixth known mass stranding for the species worldwide, the first record for pygmy killer whales for the northeastern Caribbean and the second for the entire Caribbean Sea.

Sipunculans represent a discrete component of the coral reef ecosystem, since they live inside the calcareous structure. They are an important component in terms of biomass and number of organisms. The present study describes the diversity of sipunculans living inside massive coral skeletons. A total of 43 blocks of dead coral skeletons from Montastraea cavernosa, Montastraea annularis and Diploria strigosa were collected from nearby coral reef areas off Santa Marta, on the Colombian Caribbean coast. Using hammer and chisel, blocks of approximately 1 dm3 were broken into small pieces, from which the sipunculans were extracted. A total of 381 organisms were obtained from the coral blocks comprising four families and 10 species. All the species found have been widely reported in different studies from the Caribbean region. Aspidosiphon fischeri and Phascolosoma perlucens were the two most abundant species comprising more than 60% of the total organisms with a mean density of 18.52 ± 4.64 organisms dm−3. Dead coral substrate from M. cavernosa had the greatest abundance (N = 148), followed by D. strigosa (N = 121) and M. annularis (N = 112). There were no significant differences in the abundance, richness, and diversity of sipunculans between coral skeletons; and within samples there was high variability suggesting that the skeletal substrates analysed came from coral skeletons of different unknown ages of succession. These results describe the sipunculan community structure that live inside three important massive coral skeletons, and contributes to the knowledge of the cryptobiota diversity of the Santa Marta area of Colombia.

The coccolithophorid Scyphosphaera apsteinii is here reported for the first time from waters off the west coast of the Baja California Peninsula. Scypho­sphaera apsteinii is the type species of the genus Scyphosphaera and had hitherto been recorded only in the Atlantic and Indian Oceans, the Gulf of Mexico, the Mediterranean, and the Caribbean Seas. Specimens were found in samples collected in nets off Isla de Guadalupe in January 2013. This recording thus extends the geographical distribution of S. apsteinii from the Central Pacific (Hawaii) to the Eastern Pacific (NW Mexico).

Abstract The minute red alga Crouania pumila (Callithamniaceae: Rhodophyta), recently described from the Caribbean Sea, is reported for the first time from the Red Sea, approximately 12,000 km from the type locality, based on microscope slide specimens collected 40 years ago by Dr. Yaacov Lipkin. These samples contribute new information regarding the reproduction of this algal species.
