Archive for the ‘RI37’ Category

The first main Hawaiian Island pup for 2015 was born last week to R5AY on Oahu. She’s a Kauai and Oahu seal, but mostly an Oahu seal these days. You may remember R5AY suffered from a severely hooked tongue in 2013 that required surgical removal of a portion of it. Here’s a snapshot of her life:
Background: Tagged in 2002 as an adult on Kauai – so currently at least 18 years old (assuming 5 yrs old when first seen – min age of sexual maturity)

Has mostly spent her time since between Kauai and Oahu

Pupping History

2005 – Kauai  RI37 (female)

2006 – Oahu  (female)

2008 – Oahu  (male)

2009 – Kauai  RA20 (female)

2011 – Oahu  (female)

2012 – Oahu  (female)

Interesting facts/incidents with her other pups:

– Two females died from entangling in gillnets in the Bellows/Waimanalo area on Oahu.

– RI37 has some large scars on her back – potentially from a propeller. Possibly because of the scars or other related internal injuries, she has had a history of miscarriages/abortions and stillborn pups. As of now, she has not yet had a live birth.

Hooking/Entanglement Summary for R5AY

– First reports from kite surfers near Malaekahana State Recreation Area of a seal floating entangled/dead.

– 19 November – Surgery at Honolulu Zoo w/Drs. Gregg Levine, Michelle Barbieri, and Miles Yoshioka (soft tissue surgeon). Removed ~2/3rds of her tongue

– Recovery at Waikiki Aquarium. Progressed from eating dead fish to capturing live fish in pool.

– 29 November – Released near Turtle Bay. Was fitted with satellite transmitter to track movements.

– Continued surveys by volunteers after release to track location and body condition.

– 12 December – Captured by PIFSC staff to give antibiotics, take blood sample, assess body condition. Appeared to be continuing recovery.

– Mid-January 2013 – Satellite tag stopped transmitting or fell off.

Other interesting info regarding monk seal reproduction:

– Gestation length of monk seals is unknown. Period between pup birth dates is ~381 days (on average). After 6 weeks of nursing, females are usually seen ~19 days later with scratches & injuries that imply mating. So the assumption is that gestation is somewhere around 10-11 months. But other seals have delayed implantation – so who knows?
