SUMMARIZE THE EXPERIENCES

 


 

This document purposefully focuses on creating a list of mixed-species exhibits with family Otariidae, Odobenidae and Phocidae, for further and detailed information it is worth contacting the institutions mentioned above. Only a short summary of the general experiences is given here. Many of the listed coexistences are still ongoing at present; many of them are not anymore.

 

A good advice is to base the combination on the one existing in the wild: this is also very important to respect coherence between the zoological representation of the natural environment (GILI & MEIJER & LACAVE 2018).

In the wild many otariids share haul-out areas with other pinniped species, including species of phocids. In the Southern Ocean, multiple species of fur seals haul-out at the same sites, as do sea lions and fur seals, and many locations support colonies of Southern Elephant Seals and small number of species of Antarctic seals. In the North Pacific Ocean, Steller Sea Lions and Northern Fur Seals haul-out together, as do Steller Sea Lions and California Sea Lions. Six species – two sea lions, two fur seals and two phocids – co-occur, often in close proximity to each other on several central and southern California islands (WEBBER 2014).

Further example is that California Sea Lions, Harbor Seals and Sea Otters share the same habitat in the wild. The most frequent association with pinnipeds is the California Sea Lion & Harbor Seal combination, especially in the North American institutions, but the Harbor Seal & Sea Otter combination has also tried out at least in one zoological garden.

Tiergarten Nürnberg keeps California Sea Lion breeding group together with two female Harbor Seals which combination works without problem. In the enclosure by natural choice some bird species can be observed as well, like Grey Heron, Canada Goose and Mallard. The ducks bred an raised chicks. The young Sea Lions took the chicks under water and let them plop up to the surface – just for playing. The chicks survived this regular mistreatment (MÄGDEFRAU 2018, pers. comm.).

Parque da Cabarceno in Spain keeps together California Sea Lions (2.2) and South American Sea Lions (0.2) without any problems but it is worth mentioning that male Sea Lions are castrated (GALLEGO ALDAMA 2018, pers. comm.).

Zoo Dortmund kept their California Sea Lions (3.5) together with Afro-Australian Fur Seals (4.7) many years ago. Interspecific play was observed between young animals which is also a general experience of keeping different seal species together (HAMMER 2002).

Faunia in Madrid had California Sea Lions, Afro-Australian Fur Seals and Harbor Seals together three years ago. They were living all together without any problem. The staff did all the exhibitions with all of them together in the same pool and made training sessions as well. Even the reproduction with these species together was fine, the institution had calfs of Harbor Seals and Fur Seals, too (BARRIO 2018, pers, comm.).

Los Angeles Zoo kept their California Sea Lions (1.2) together with Capybaras some decades ago. The species swam and basked together. One adult female Capybara behaved aggressively against a newly naturalized young male Sea Lion which was taken out of the group (CROTTY 1981, HAMMER 2002).

An unknown institution has had a very complex combination with California Sea Lions, Northern Elephant Seal, Celebes Crested Macaques, Geladas and Capybaras. All the species kept in breeding group except the elephant seal (one female only). There was a pool with two islands on it, Macaques one one and Geladas on the other (THOMAS & MARUSKA 1996).

Tiergarten Nürnberg combined their California Sea Lion group (1.4) with Common Bottlenose Dolphin group (1.4) many years ago (HAMMER 2002). The association of the two species started in 1991 and the initial group structure was one juvenile male of sea lion with one juvenile male and two adult females of dolphins, later on changed to an abovementioned group. The volume of the pool was 1500 m³ with an adjoining 100 m² dry and roofed area for the sea lions. The enclosure was equipped with several toys and animals took part in a training program several times a day. Frequent interspecific interactions including physical contacts and simple interspecific communication between certain individuals of both species. Close sociopositive relationships were observed between the adult male sea lion and a certain female dolphin (partly resembling mating behaviour) as well as between a female sea lion and another female dolphin (playful behaviours). The other individuals sporadically join these "interspecific couples" but they are predominantly involved in intraspecific interactions. Newborn sea lions have to be separated from dolphins to prevent them from being maltreated as playmates. Sea lions and dolphins were trained and fed separately (ZIEGLER 2002). The Sea Lions had opportunity for retreat. The species were separated during feeding and Sea Lions for rearing of young, too. Afro-Australian Fur Seals were also combined with the dolpins in Nürnberg but no interspecific interactions were observed (HAMMER 2002).

Although Sea Lions get on well with dolphins and it is a very attractive mixed exhibit, leading dolphin trainers recommend that for the Sea Lions enough exits off the water should be available. These ways of flight are necessary because dolphins are sometimes very rude while playing. In addition it is recommended that leading female Sea Lions with their offspring should be separated that long till the youngsters are quick enough to escape from the dolphins (HAMMER 2002).

Riyadh Zoo in Saudi Arabia combined two species of otariids with two species of phocids – South American Sea Lions (1.1), Australian Sea Lion (0.1), Grey Seals (1.2) and Harbor Seals (1.1) – together. The male South American Sea Lion was the dominant, but not aggressive during feeding time (HAMMER 2002).

 

Even the Walrus can be kept together with smaller species of seals, although it is known from the wild that Walruses chase seals (HAMMER 2002). The Walrus’s main source of food is benthic invertebrates, in large part, bivalve mollusks found in the sediment in high-density beds. Their diets are variously supplemented with amphipods, snails and soft-shelled crabs. It is worth mentioning that occasionally, Walruses hunt and eat Northern Fur Seals, Bearded Seals, Ringed Seals and Spotted Seals (STEWART 2014).

Zoo Hannover kept Walrus and Southern Elephant Seal together in the 1960s but both of the animals were young and sexually immature (MÜLLER-SCHILLING 2018, pers. comm.).

PUSCHMANN (1983) quotes examples of associations of a six years old Walrus with Sea Lions and Grey Seal as well.

 

According to Best Practice Guidelines for Otariidae and Phocidae Earless Seals can be better accommodated in a mixed exhibit than Eared Seals (GILI & MEIJER & LACAVE 2018).

Los Angeles Zoo kept their female Grey Seals (0.3) together with Nort American River Otters (2.2) some decades ago. First the otters avoided water but in the meantime they swam around the seals (CROTTY 1981, HAMMER 2002).

Harbor Seals have been maintained in some instances with female or young Grey Seals as males might be very aggressive towards the individuals of the smaller species. A strong attention should always pay to the dominance that can emerge during feeding time. For this reason it might be easier to base the combination on differences in dominance and combine aggressive with non-aggressive species (GILI & MEIJER & LACAVE 2018).

København Zoo kept their female Harbor Seals (0.3) together with a herd of Reindeer. The species were always together: it was possible for reindeer to cross stone barrier and drank from the seal pool. Reindeer sometimes swam in the seal pool (HAMMER 2002).

Dierenrijk in the Netherlands have kept together Harbor Seals and White-tailed Sea-eagles in a walk-through aviary for more than six years without problems. When the staff fed the seals the eagles stayed in the sitting tree. As the birds started to breed and with visitors in the same enclosure this was to dangerous the institution sent them away to an other zoo (RIJNEN 2018, pers. comm.).

 

In mixed-species exhibits with different species of pinnipeds together it should be thought of a danger of hybridisations. Scattered crossings already occured between Arctocephalus pusillus x Zalophus californianus, Halichoerus grypus x Pusa hispida (HAMMER 2002), Zalophus californianus x Otaria byronia (BRUNNER 2002), Callorhinus ursinus x Zalophus californianus (DUFFIELD 1999, MILLER et al. 1996), Eumetopias jubatus x Zalophus californianus (GORODEZKY 1995, MILLER et al. 1996), Arctocephalus australis x Otaria byronia (MILLER et al. 1996), Arctocephalus forsteri x Arctocephalus gazella (GOLDSWORTHY 1999, GOLDSWORTHY et al. 1998, 1999, SHAUGHNESSY et al. 1998.), Arctocephalus forsteri x Arctocephalus tropicalis (GALES et al. 1992, SHAUGHNESSY 1992), Arctocephalus gazella x Arctocephalus tropicalis (GALES et al. 1992, GOLDSWORTHY et al. 1998, 1999, GUINET et al. 1994, St. CLAIR HILL et al. 2001, WYNEN et al. 2001), Arctocephalus townsendi x Callorhinus ursinus (JAMEYSON et al. 1981), Pagophilus groenlandicus x Cystophora cristata (KOVACS et al. 1997), Halichoerus grypus x Pusa hispida (LÖNNBERG 1929, MOHR 1940), Phoca largha x Phoca vitulina (KATSUMATA et al. 2003).
